Cycle Life Of Batteries

- Dec 13, 2018-

Cycle life of battery depends on several factors, some of which are as under—

  1. Temperature of battery

  2. Charging level

  3. Depth of discharge

  4. Rate of charge / discharge

  5. Battery type and storage conditions

Under standard conditions, and when discharge cycle is from fully charged condition to 80% DOD, Li ion battery has cycle life of about 1000 — 1500 cycles, as against that of 500 — 700 maximum for lead acid battery.

We can extend the usable life of battery by opting for lower DOD, meaning say, recharge after 30– 40 % DOD, and further increase possible by keeping battery temperature in the most favourable limits.
