1. Battery Technology Overview — Four Core Platforms
We manufacture across four lead-acid battery platforms. Each serves a distinct market segment and vehicle type. Understanding the differences helps you select the right products for your market.
1.1 SLI Starting Batteries — Standard Flooded
The foundational automotive battery technology. SLI (Starting, Lighting, Ignition) batteries deliver a short, high-current burst to crank the engine, then recharge from the alternator. This category represents the largest share of the global automotive aftermarket — an estimated 400 million units annually according to industry estimates from the International Lead Association.
Construction & Chemistry
A standard SLI battery contains six 2V cells connected in series to produce 12V. Each cell holds positive plates (lead dioxide, PbO₂), negative plates (sponge lead, Pb), and separators, immersed in dilute sulfuric acid electrolyte (typically 1.260–1.280 specific gravity at full charge).
Our SLI batteries use:
- Calcium-calcium (Ca-Ca) alloy grids — reduces water loss by approximately 80% compared to traditional lead-antimony grids. Self-discharge rate is approximately 3–5% per month at 25°C, enabling maintenance-free designs.
- Calcium-silver (Ca-Ag) alloy grids — added silver (0.03–0.05%) improves corrosion resistance at elevated temperatures. Recommended for hot-climate markets where under-hood temperatures regularly exceed 60°C.
- Envelope polyethylene (PE) separators — ribbed, low-resistance separators wrapped around each positive or negative plate. PE envelope design prevents internal shorting from active material shedding and improves vibration resistance.
| SLI Technical Parameters | Typical Range |
|---|---|
| Nominal voltage | 12V (6 cells × 2V) |
| CCA rating (SAE) | 300–950 A |
| Reserve capacity (RC) | 60–180 min |
| 20-hour capacity (C20) | 35–100 Ah |
| Self-discharge (25°C) | 3–5% per month (Ca-Ca) |
| Water loss (60°C overcharge) | ≤ 4 g/Ah (maintenance-free) |
| Design life (normal use) | 3–5 years |
| Operating temperature | -30°C to +60°C |
Market Applications
Passenger cars, SUVs, light commercial vehicles (LCV), motorcycles (small-frame), and marine starting applications where the alternator provides the primary electrical supply after starting. Not recommended for deep-cycling applications — repeated discharge below 50% state of charge significantly reduces service life.
Available as OEM: Standard or maintenance-free. Custom case, terminal, handle, and label configurations.
1.2 AGM Batteries — Absorbent Glass Mat (VRLA)
AGM technology represents the premium tier of lead-acid starting batteries. The electrolyte is absorbed in a fiberglass mat separator rather than flowing freely. This design enables higher performance, longer cycle life, and spill-proof operation — critical for modern vehicles with aggressive fuel-saving technologies.
How AGM Works
In an AGM battery, micro-glass fiber separators hold the sulfuric acid electrolyte in suspension between the plates. The cell operates under slight pressure with a recombinant design: oxygen generated at the positive plate during charging recombines at the negative plate, converting back to water. This closed-loop system eliminates the need for watering and prevents acid leakage.
Key Advantages Over Standard Flooded
| Performance Metric | Standard Flooded | AGM | Advantage |
|---|---|---|---|
| Cycle life (50% DoD) | 150–200 cycles | 400–600 cycles | 2–3× longer |
| Charge acceptance | 0.2–0.3 C | 0.5–1.0 C | 2–3× faster recharge |
| Internal resistance | 4–8 mΩ | 2–4 mΩ | Lower voltage drop |
| Vibration resistance | Moderate | High | Compressed element stack |
| Cold cranking performance | Standard | Superior | Lower internal resistance at -18°C |
| Deep discharge recovery | Poor | Good | Recombinant chemistry |
| Mounting orientation | Upright only | Any angle (spill-proof) | Flexible installation |
Technical Specifications
- Plate technology: Thin-plate pure lead (TPPL) or high-purity lead-calcium-tin alloy grids for reduced gassing and grid corrosion
- Separator: Compressed micro-glass fiber mat (AGM) with 90–95% porosity for acid retention and oxygen transport
- Pressure relief valve: Opens at 7–14 kPa (1–2 psi) to prevent excessive internal pressure during overcharge events
- Electrolyte: 1.300–1.320 specific gravity, starved-electrolyte design (acid volume limited to what the glass mat can absorb)
- Recombination efficiency: ≥ 99% under controlled charging — no water loss over service life
Application Requirements
AGM batteries are specified (not optional) for most vehicles with start-stop systems, regenerative braking, and advanced energy management. These vehicles demand:
- Rapid charge acceptance during braking energy recovery
- Repeated engine-off restarts without voltage sag
- Stable power delivery to sensitive electronics during engine stop phases
- Deep partial-state-of-charge cycling (typically 70–85% SoC in start-stop mode)
Vehicles with advanced start-stop and brake energy recuperation — such as many European models from 2015 onward and North American models from 2018 onward — require AGM or EFB technology. Installing a standard flooded battery in these vehicles results in premature failure, typically within 6–12 months of normal driving.
1.3 EFB Batteries — Enhanced Flooded Battery
EFB technology bridges the gap between standard flooded SLI batteries and premium AGM. It is the cost-effective entry point for start-stop vehicles with moderate electrical demands.
Construction Differences from Standard SLI
| Component | Standard Flooded | EFB |
|---|---|---|
| Positive plate grid | Lead-calcium alloy | Lead-calcium-tin with higher tin content (1.2–1.8%) for corrosion resistance |
| Positive active material | Standard lead dioxide paste | Carbon-enhanced paste with polyester scrim reinforcement |
| Negative active material | Standard sponge lead | Carbon additive (0.2–2.0%) for improved charge acceptance |
| Separator | PE envelope | PE envelope with enhanced pore structure |
| Electrolyte | Standard 1.260–1.280 SG | Higher-density 1.280–1.290 SG with additives |
| Cycle life (50% DoD) | 150–200 cycles | 300–400 cycles |
| Water consumption | Standard | Reduced — approximately 1 g/Ah lower than standard |
Where EFB Fits
EFB is the correct choice when:
- The vehicle has entry-level start-stop (engine-off at traffic lights only, no regenerative braking)
- The original battery was specified as EFB (common in Japanese and some European compact cars)
- Budget constraints make AGM unfeasible, but standard flooded will not survive start-stop duty
EFB should NOT be used in vehicles requiring AGM as specified by the manufacturer. Installing EFB where AGM is required typically results in failure within 12–18 months due to insufficient charge acceptance under regenerative braking conditions.
1.4 Heavy Duty Batteries — Commercial Vehicle & Equipment
Heavy-duty batteries power trucks, buses, construction machinery, agricultural equipment, marine applications, and stationary engines. The operating environment is severe: high vibration, wide temperature swings, deep cycling, and extended idle periods.
Design Features
- Thicker positive grids — 2.0–3.5 mm grid thickness vs. 1.2–1.8 mm in passenger car batteries. Thicker grids resist corrosion over longer service lives and tolerate deeper cycling.
- Reinforced element construction — plates are anchored with epoxy or hot-melt bonding to the case floor, preventing internal movement under vibration. Element compression maintained through the full service life.
- High-density active material — positive paste density of 4.0–4.2 g/cm³ (vs. 3.8–4.0 for standard SLI) for improved cycling endurance.
- Heavy-duty terminals — cast lead terminals with brass inserts on stud-type configurations. Threaded connections resist loosening under vibration better than tapered post terminals.
- Double lid / labyrinth lid — flame arrestor vents and spill-resistant designs for commercial vehicle safety compliance (compliant with European standard EN 50342-2 for heavy-duty batteries).
| Heavy Duty Category | Typical CCA Range | Typical C20 Range | Vehicle Types | Terminal Standard |
|---|---|---|---|---|
| Group 31 | 900–1,150 A | 100–120 Ah | Trucks, buses, off-road | SAE post / stud |
| 4D | 900–1,350 A | 150–200 Ah | Heavy trucks, marine | SAE post / stud / flag |
| 8D | 1,300–1,600 A | 220–260 Ah | Large marine, stationary | SAE post / stud / flag |
| DIN HD | 600–900 A (EN) | 100–225 Ah | European trucks, buses | DIN taper |
| JIS HD | 500–900 A (JIS) | 70–200 Ah | Japanese trucks, construction | JIS taper |
2. Battery Technology Selection Guide
Choosing the right battery technology depends on the vehicles in your target market. Use this table to match battery type to application.
| Vehicle / Application | Recommended Battery | Notes |
|---|---|---|
| Standard gasoline/diesel without start-stop | SLI (standard flooded) | Most cost-effective. Maintenance-free recommended for aftermarket. |

| Start-stop with regenerative braking | AGM | Required. EFB will not provide sufficient charge acceptance. |
| Luxury / high-spec vehicles | AGM | Higher electrical loads and multiple ECUs demand stable voltage. |
| Hybrid (non-plug-in) auxiliary battery | AGM | AGM handles partial-state-of-charge cycling in 12V auxiliary role. |
| Trucks, buses, off-road (24V system) | Heavy Duty × 2 (series) | Two 12V HD batteries wired in series. Match age and capacity. |
| Marine starting | HD or AGM | AGM for deep-cycle tolerance; HD for pure cranking. |
| Agricultural / construction | Heavy Duty | High vibration resistance required. Maintenance-free HD with stud terminals preferred. |
| UPS / standby power | VRLA (AGM or gel) | Deep-cycle design. Contact us for UPS-specific product range. |
3. Regional Standards — Cross-Reference Matrix
The same battery chemistry ships to 70+ countries — but the case dimensions, terminal types, and performance rating methods change by region. This table maps our manufacturing standards to target markets with typical battery models.
| Standard | Primary Markets | Case Reference System | Terminal Types | CCA Rating Method | Common Models Produced |
|---|---|---|---|---|---|
| JIS | Japan, Southeast Asia, Middle East, Africa, Oceania | B/D series (B19–D31, G51–F51) | JIS taper (T1 thin / T2 thick), bolt-through | JIS D5301 (-18°C) | 40B19L, 55D23L, 65D26L, 75D26L, 80D26L, 95D31L, 115D31L, 130D31L, 145G51, 150F51, 170F51, N40, NS60, NS70 |
| DIN / EN | Europe, Russia, CIS, South America | LN series (LN1–LN5) and H/T series (540–680) | DIN taper, SAE post, bolt-through | EN 50342-1 (-18°C) | LN1, LN2, LN3, LN4, LN5, 540 126 033, 560 130 053, 585 200 080, 600 138 074, 610 170 090, 620 190 100, 630 210 110, 640 230 125 |
| BCI | USA, Canada, Mexico, Central America, Caribbean | Group numbers (24–96R, 4D, 8D) | SAE post (top and/or side), dual terminal | SAE J537 (-18°C) | Group 24, 24F, 27, 27F, 34, 34/78, 35, 51R, 58, 65, 75, 78, 86, 94R / H7, 96R, 48 / H6, 49 / H8, 31, 4D, 8D |
| AS | Australia, New Zealand, Pacific Islands | Australian model numbers (N-series, century-equivalent) | SAE post, JIS taper | AS 2149 (-18°C) | NS40ZL, N50ZL, N70ZL, N70ZZL, N150, 55D23L, 75D23L, 80D26L |
| SA | South Africa, neighboring markets | SA model numbers (600-series) | SAE post, DIN taper, bolt-through | SANS 2 (-18°C) | 638, 640, 646, 647, 652, 654, 657, 658, 668, 671 |
Note: CCA ratings are not directly comparable across standards. SAE J537 CCA is typically 10–20% higher than EN 50342-1 CCA for the same battery, and JIS D5301 uses a different test procedure entirely. When specifying battery requirements, always indicate the test standard. We cross-reference ratings during engineering to ensure the battery meets your market’s labeling requirements.

9. Frequently Asked Questions
Q1. Can I see your technical specification sheets before ordering?
Yes. Specification sheets for our standard battery models are available on request. These include dimensional drawings, terminal configurations, CCA/RC/C20 ratings, and performance curves. For custom OEM specifications, our engineering team provides a detailed specification sheet with your first quotation.
Q2. How do you ensure quality consistency between production batches?
We operate under IATF 16949 quality management, which mandates statistical process control (SPC) at every production stage. Key parameters — grid thickness, paste density, plate weight, COS weld strength, formation charge profiles, and CCA output — are monitored continuously. Test data is retained for every production lot. You can request batch-specific test reports with any order.
Q3. Can you match the specifications of a battery I am currently importing from another factory?
Yes. Send us the battery model number, case dimensions (L×W×H), terminal type and position, CCA rating (and the test standard used), reserve capacity, and capacity (C20). Our engineering team will produce a cross-reference specification and a pre-production sample for your approval. We match or exceed your current specifications — not as a claim, but as a documented test result.
Q4. How do CCA ratings differ between JIS, DIN, and BCI?
CCA test methods differ. SAE J537 CCA (USA) tests at -18°C for 30 seconds, requiring voltage ≥ 7.2V. EN 50342-1 (Europe) also tests at -18°C but requires voltage ≥ 7.5V after 10 seconds and ≥ 7.2V after 30 seconds — a stricter standard. JIS D5301 uses a different test procedure and cannot be directly compared. Our engineering team handles the cross-referencing. Tell us the standard your market uses and the CCA number you want on the label — we engineer to that target.
Q5. What happens if a battery fails your in-house testing before shipment?
Batteries that do not pass 100% testing (OCV, CCA, RC, leak test) are rejected and recycled through our in-house recovery system. Lead is reclaimed and returned to the smelting process. No battery leaves our factory without passing every required test. This is not a sampling check — it is a 100% test on every unit for the critical parameters listed in Section 5.2.
Q6. How long do your batteries last in real-world conditions?
Service life depends on the battery type, vehicle, climate, and driving pattern. Based on field data from our distribution partners:
- SLI (standard flooded) in moderate climates: 3–5 years
- SLI in hot climates (Middle East, North Africa): 2–3.5 years
- AGM in start-stop vehicles: 4–7 years
- EFB in entry-level start-stop: 3–5 years
- Heavy duty in truck fleet service: 2–4 years (high vibration, high cycle demand)
These are field-observed ranges, not warranty periods. Actual performance varies by usage.
Q7. Do you offer warranties on OEM batteries?
Warranty terms are agreed per order and per market. As a factory-direct OEM supplier, we stand behind our manufacturing quality. Typical OEM warranty approaches: pro-rata replacement credit for manufacturing defects confirmed by root cause analysis; or a negotiated warranty reserve built into the purchase price. Terms are finalized at the purchase agreement stage.
Q8. Can you ship samples before I commit to a full container?
Yes. We produce pre-production samples — typically 5–10 batteries per model — on the same production lines used for your bulk order. Sample cost: unit price plus shipping. Sample cost is credited back against your first bulk order if the order proceeds. Sample lead time: 7–15 working days from specification confirmation.
Q9. How do you handle battery transport? Are there DG (dangerous goods) complications?
Yes — flooded lead-acid batteries with free electrolyte are classified as UN 2794, Class 8 dangerous goods for sea transport. We provide the required MSDS, DG declaration, and packaging certification. AGM and VRLA batteries classified as UN 2800 (non-spillable) ship under reduced requirements. We manage all DG documentation as part of our standard export service.
Q10. How do I get started if I have never imported batteries from China before?
Contact our sales team with your target market, vehicle types, and estimated volumes. We walk you through the process:
- Specification matching (tell us what you need or what you currently buy)
- Quotation (FOB/CIF pricing, lead time, payment terms)
- Sample production and approval
- Production scheduling
- Our export team handles documentation and coordinates with your freight forwarder
- Container ships to your port
We work with first-time importers regularly. Our export documentation package is complete and carrier-compliant — we have never had a container held at destination for paperwork issues.
