  2. Peukert's law - Wikipedia

    en.wikipedia.org/wiki/Peukert's_law

    For a real battery the exponent is greater than unity, and capacity decreases as discharge rate increases. For a lead–acid battery k {\displaystyle k} is typically between 1.1 and 1.3. For different lead–acid rechargeable battery technologies it generally ranges from 1.05 to 1.15 for VRSLAB AGM batteries , from 1.1 to 1.25 for gel , and ...

  3. Depth of discharge - Wikipedia

    en.wikipedia.org/wiki/Depth_of_discharge

    While the state of charge is usually expressed using percentage points (0 % = empty; 100 % = full), depth of discharge is either expressed using units of Ah (e.g. for a 50 Ah battery, 0 Ah is full and 50 Ah is empty) or percentage points (100 % is empty and 0 % is full). The capacity of a battery may also be higher than its nominal rating.

  4. Cutoff voltage - Wikipedia

    en.wikipedia.org/wiki/Cutoff_voltage

    A high cut-off voltage is more widespread than perhaps assumed. For example, a certain brand of mobile phone that is powered with a single-cell Lithium-ion battery cuts off at 3.3 V. The Li‑ion can be discharged to 3 V and lower; however, with a discharge to 3.3 V (at room temperature), about 92–98% of the capacity is used. [2]

  6. State of charge - Wikipedia

    en.wikipedia.org/wiki/State_of_charge

    State of charge (SoC) quantifies the remaining capacity available in a battery at a given time and in relation to a given state of ageing. [1] It is usually expressed as percentage (0% = empty; 100% = full). An alternative form of the same measure is the depth of discharge , calculated as 1 −

  7. Lithium-ion battery - Wikipedia

    en.wikipedia.org/wiki/Lithium-ion_battery

    The lifespan of a lithium-ion battery is typically defined as the number of full charge-discharge cycles to reach a failure threshold in terms of capacity loss or impedance rise. Manufacturers' datasheet typically uses the word "cycle life" to specify lifespan in terms of the number of cycles to reach 80% of the rated battery capacity. [158]
