My baterry dosen't charge

hi

try the classic electric jumpstart

take a source like an adapter or some which has an output voltage of atleast 3 times that of the battery like say if you have a AA size NIMH battery then try using a 5Volt adapter with atleast 500MA

now hold the positve wire to the +ve of the batter and negative wire to the - ve of the battery (BE SURE OF THE POLARITIES esle u'll destoy the batery completly) and hold it for not more than 10-15 secs and then quickly place for charging in the battery charger

do this in 2 - 3 charge discharge cycle

cheers
pls rate if it was any help
