2. Battery regenerator - Wikipedia

   en.wikipedia.org/wiki/Battery_regenerator

   As the battery fills, its internal voltage rises towards the fixed voltage being supplied to it, and the rate of current flow slows. Eventually the charger will turn off when the current drops below a pre-set threshold. [4] A sulfated battery has higher electrical resistance than an unsulfated battery of identical construction.

3. Charge cycle - Wikipedia

   en.wikipedia.org/wiki/Charge_cycle

   A "charge cycle" is not a unit of time; the length of time spent charging or discharging does not affect the number of charge cycles. [1] Each battery is affected differently by charge cycles. [2] [3] In general, number of cycles for a rechargeable battery (the cycle life) indicates how many times it can undergo the process of complete charging ...

4. Self-discharge - Wikipedia

   en.wikipedia.org/wiki/Self-discharge

   How fast self-discharge in a battery occurs is dependent on the type of battery, state of charge, charging current, ambient temperature and other factors. [2] Primary batteries are not designed for recharging between manufacturing and use, and thus to be practical they must have much lower self-discharge rates than older types of secondary cells.

5. 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 ...

6. Lead–acid battery - Wikipedia

   en.wikipedia.org/wiki/Lead–acid_battery

   The sum of the molecular masses of the reactants is 642.6 g/mole, so theoretically a cell can produce two faradays of charge (192,971 coulombs) from 642.6 g of reactants, or 83.4 ampere-hours per kilogram for a 2-volt cell (or 13.9 ampere-hours per kilogram for a 12-volt battery).

7. Capacity loss - Wikipedia

   en.wikipedia.org/wiki/Capacity_loss

   Capacity loss or capacity fading is a phenomenon observed in rechargeable battery usage where the amount of charge a battery can deliver at the rated voltage decreases with use. [ 1 ] [ 2 ] In 2003 it was reported the typical range of capacity loss in lithium-ion batteries after 500 charging and discharging cycles varied from 12.4% to 24.1% ...
