I would like to charge a pair of 3.7V, 1500mAh Li-ion cells but I do not have a charger for them. I would like to use a normal power supply to chrage them I just dont know what voltage and current i should put across and through the cells and for how long I charge them. Also I am not even sure if they are charged (I assume not because they are brand new) is there an easy way to check this? Failing an answer does anyone know what charger I could buy to do the job? Thanks
