2016 BMW 535i Car Battery BCI Group 49 / H8 Replacement Lithium LiFePO4 Automotive Battery

MORE POWER - The rated voltage of our batteries is about 0.8V higher than a lead-acid battery, meaning the battery has more discharge power. As a result, it can improve the combustion efficiency of the fuel in the engine cylinder. So when using this battery you may feel the car start faster, has lower fuel consumption, lighter throttle, more responsive engine and more power! LIGHTWEIGHT – Powertex’s LiFePO4 BCI Group 49 / H8 battery weighs in at 21.2 lbs compared to the standard lead acid equivalent which weighs a whopping 58.6 lbs. BATTERY MANAGEMENT SYSTEM - PowerTex LiFePO4 Lithium Iron Phosphate Batteries come standard with a built-in BMS (Battery Management System) that protects it from the most common causes of battery failure. GRADE A CELLS - Powertex LiFePO4 Lithium Iron Phosphate car batteries provide the highest level of Grade and reliability. Don't be fooled by the competition, our cells are UL certified. Our batteries UN38.3 & RoHs certified. LONGEVITY – Powertex LiFePO4 automotive batteries provide more than 2,000 cycles at 80% DOD (depth of discharge). This is compared to a lead acid battery that only offers 200 ~ 500 cycles. As a result, our lithium iron phosphate batteries have a lifespan of about 5 to 10 years. WARRANTY - We stand by and believe in our products and think you should too! That's why we test all batteries bee shipping and offer a 2 Year warranty. CHARGING - A LiFePO4 charger is highly recommended since SLA chargers might not reach the optimal 14.4V-15V LiFePO4 charging voltage. This might result in the LFP battery never reaching it's full charge and thus lowering the permance.
