Terli
Product Feature
1. Safety Performance: safest Lithium Iron Phosphate battery, CE IEC UN38.3 approved, built-in BMS
2. Long Cycle Life: > 4000 times, 6-8 times life cycle compare to lead acid battery
3. Deep cycle, no memory effect, highly efficient
4. Compact size and light weight: 1/2 size & weight of lead acid battery
5. Good performance at high temperature
6. Low self-discharge rate: < 3% month
Switching from lead-acid to a LiFePO4 starting battery cuts replacement frequency by 6–8× while reducing battery weight by half. The comparison below uses verifiable specifications from both chemistries.
| Factor | LiFePO4 (TY-12-75) | Lead-Acid |
|---|---|---|
| Cold Cranking Amps | 800CCA at -20°C | 500CCA, fails below -10°C |
| Cycle Life | 4,000–6,000 cycles | 300–500 cycles |
| Service Life | 5 years (warranty-backed) | 1–2 years |
| Weight | 6.5 kg | ~13 kg equivalent |
| Usable Capacity | 100% DOD | ~50% usable |
| Safety | No acid leak, no thermal runaway | Acid leak risk |
| Eco Impact | Recyclable, no toxic materials | Lead and acid disposal required |
| Charger Compatibility | Works with standard lead-acid chargers | N/A |
No memory effect and zero maintenance requirements further extend the effective service interval between replacements.
The Terli 12V 75Ah LiFePO4 car starter battery uses aluminum-shell Grade A LiFePO4 cells — a chemistry that resists thermal runaway under overcharge or high-temperature conditions. An integrated BMS manages all cell units automatically to extend service life and prevent electrical faults.
BMS protection functions:
Overcharge protection: Disconnects the charge circuit when voltage exceeds the safe threshold
Over-discharge protection: Prevents cell damage from deep depletion
Overcurrent protection: Limits current draw to rated parameters
Short circuit protection: Instant cutoff on detected short
High/low temperature disconnect: Suspends operation outside the safe thermal range
Overvoltage protection: Guards against voltage spikes from the charging source
Overload protection: Prevents sustained power draw beyond rated output
Automatic cell balancing: Equalizes cell voltage across the pack continuously
Automatic fault recovery: Resets protection state after the fault clears
Flame-retardant electrolyte: Passive safety layer against ignition
Internal cell thermal safety fuse: Hardware-level thermal cutoff independent of BMS
Importing a 12V 75Ah LiFePO4 car starter battery into regulated markets requires full documentation across safety, transport, and environmental standards. Every unit ships with the following verified certifications:
CE: EU market access — confirms compliance with safety, health, and environmental protection requirements
IEC: International Electrotechnical Commission standard compliance
UN38.3: Authorizes safe air and sea transport of lithium batteries internationally
TUV: Third-party safety testing and certification
EN62619 / IEC62040: Battery safety and UPS standard compliance
CEC Accredited: California Energy Commission accreditation for the US market
RoHS: Confirms absence of restricted hazardous substances
ISO9001: Quality management system certification covering the full production process
Unit-level quality assurance:
100% pre-shipment electrical testing on every battery
Matched voltage and internal resistance verified per unit
Online video inspection available before shipment
Terli supports full private-label production of the 12V 75Ah LiFePO4 car starter battery — including custom logo, case color, dimensions, and retail packaging. Brand owners launching a lithium car battery product line can enter with a single sample unit and scale on their own timeline.
Sample orders ship in 3–7 days. Mass production delivers in 7–20 days depending on order volume. The standard TY-12-75 form factor (200×200×170 mm) can be modified; the full capacity range spans 45Ah to 120Ah within the 12V series.
Every OEM order includes a 5-year warranty, 100% pre-shipment electrical testing, and full after-sales technical support. A full refund applies if delivered units do not match the confirmed sample quality. Shipping options include air, sea, train, and DDP — supporting direct landed delivery to your warehouse.
The 12V 75Ah LiFePO4 car starter battery drops directly into any vehicle using a Group 24 AGM, GEL, or lead-acid battery — no wiring modification required. The 200×200×170 mm form factor and Anderson-compatible terminals allow installation across a wide range of platforms.
Compatible vehicle types:
Sedans, pick-up trucks, SUVs
Motorcycles
RVs and motorhomes
Extended industrial applications:
Forklifts
Communication base stations
Motor thrusters
Mountain power generation systems
This lithium car battery replacement supports series connection up to 51.2V and two-unit parallel configuration for higher-voltage applications. It charges with standard lead-acid chargers — eliminating charger replacement costs at the point of installation. A fitment guide is available to confirm model compatibility before ordering.
