NiMH batteries can be fast charged (on high current for several hours, at the risk of overheating), slow charged (for about 12–16 hours using a lower current), or briefly trickle charged (with a much lower current than nicad), but they should really be charged only with an NiMH charger: a rapid nicad charger may overcharge NiMH batteries.
Older rechargeable batteries would wear out completely after around 1,000 charges, but more modern rechargeable batteries have a higher capacity and can be fully charged for 1,000 cycles before they even start to lose overall capacity. There are essentially three types of rechargeable batteries: 1. Nickel-Cadmium (NiCd)
In theory, a 6 volt 5 Ah battery and a 12 volt 5 Ah battery connected in series will give a supply of 18 volts (6 volts + 12 volts) and 5 Ah. A 6 volt battery is often three 2 volt cells and a 12 volt battery is usually six 2 volt cells. Therefore, all you have done is connected nine 2 volt cells together to get 18 volts … so what''s the ...
At this point the capacitor is said to be "fully charged" with electrons. The strength or rate of this charging current is at its maximum value when the plates are fully discharged (initial condition) and slowly reduces in value to zero as the plates charge up to a potential difference across the capacitors plates equal to the source voltage.

Yes, cycling can help extend your battery life. When a fully charged lithium battery is drained to 25% SoC (black), the capacity loss is the greatest; if entirely depleted, the capacity loss would be even more. Charging to 100% and draining to 50% results in a shorter lifespan than cycling between 85 and 25% (green or dark …

The time it takes for the rechargeable batteries to be fully charged depends on the type of charger. However, if you use a regular charger for your AA batteries, you can expect one battery to be fully charged in six hours. So, simultaneously charging two batteries takes 7–13 hours. Meanwhile, AAA batteries take up to 6–9 hours to be 100% full.
