[Batter]

Sevral days ago, I bought a battery charger which I want from [banned]. In order to buy what I need , the suitable product, I collected a lot of information, Now I post it here, hope it is useful for you.
Use the correct charger for battery chemistry. Most chargers serve one chemistry only.

The battery voltage must agree with the charger. Do not charge if different.

Within reasons, the Ah rating of a battery can be higher or lower than specified. A larger battery will take longer to charge than a smaller one and vice versa.

The higher the amperage of the charger, the shorter the charge time will be. There are limitations as to how fast a battery can be charged.

Accurate charge termination and correct trickle charge prolong battery life.

When fully saturated, a lead acid charger should switch to a lower voltage; a nickel-based charger should have a trickle charge NiMH; a Li-ion charger provides no trickle charge.

Chargers should have a temperature override to end charge on a malfunctioning battery.

Observe the temperature of the charger and battery. Lead acid batteries stay cool during charge; nickel-based batteries elevate the temperature towards the end of charge and should cool down after charge; Li-ion batteries should stay cool throughout charge.
