Battery pack life

How long does a battery pack last?

Battery Pack Lifespan: Due to the consistency issues of battery cells, the lifespan of the battery pack is determined by the worst-performing cell. For NMC packs, this means the cycle life is reduced by 80%, resulting in 1200–1600 cycles. For LFP packs, the reduced cycle life is approximately 3200 cycles.

How long do battery cells last?

Because battery cells have a characteristic that their lifespan varies when charged at different rates. For example, a battery cell with a cycle of 0.5C charging and 1C discharging has a lifespan of 2000 cycles. However, when the charging rate is increased to 1C, this lifespan will decrease to 1800 cycles.

How long do lithium batteries last?

Lithium batteries have transformed energy storage, but their lifespan varies dramatically – from 300 cycles for standard Li-ion to 7,000+ cycles for LiFePO4. As specialists in custom 18650, Li-ion, LiFePO4, and lithium polymer battery packs for global customers, we’ve compiled this data-driven guide to help you maximize your battery investments.

How long do EV batteries last?

The larger lithium-ion battery packs inside electric cars have cycle life ratings from 1,000 (Nissan Leaf) up to around 4,000 cycles (Tesla). Translating cycles to years depends on usage patterns, but most EV batteries should deliver 8-10 years or 150,000 – 200,000 miles before range capabilities drop below 70-80%.
