A friend with an old irobot roomba mopping robot, come to me with his damaged battery.
He left home for an hollyday, disconnecting all his electric stuff,
When he came back the roomba robot charges no more.
Quite shure some of the cells of the battery (old nimh cells) where gone down and the irobot chared triggers an alarm.
No way to open it up and replace single cells. Better buy a new compatible cell , but i'll try to recover it with my imax b6 charger and seems with big success :D
Have fun.
if you prefere, that's a replacement battery: amzn.to/40NkW10 (batteria di ricambio compatibile)
If you wanna try, that's the charger (comes with the power supply): amzn.to/3lmOFxm (caricabatterie professionale imax b6)
Do you need a multimeter? amzn.to/3I9AIvJ (ottimo multimetro digitale)
