Rechargeable batteries

Special attention has been devoted to Rechargeable batteries. (The correct name is Rechargeable accumulators, but Rechargeable batteries is more popular). Typically we used 2 different chargers. If we had available the charger from the same manufacturer, we used dedicated charger. In other cases we used microprocessor controlled chargers. (We did not use 1 hour charger or any kind of quick charger). Rechargeable batteries do not keep capacity for the long time. That is why we fully charged the batteries, put them aside and re-tested after some months to see which capacity they lost.
There is a new generation of Rechargable battery called Ready to use Rechargeable battery or Low Self - Discharge (LSD) batteries. These batteries cumulate the advantage of Alkaline batteries (long duration of capacity) and Rechargeable accumulators (re-charge about 1000 times.
Rechargeable batteries in different capacities are produced by each munufacturer, such as Energizer, Duracell, Varta, Philips, Panasonic, Sanyo etc..
