True, but OP must be planning to flatten the next battery as well
(otherwise he wouldn't need the charger).

You use the charger before the battery is flat?

An ordinary charger can do this, surely?

My understanding is that OP is looking for a special charger that can
recharge flat battery (.Requirement #1 is to be able to charge flat
batteries').
