Hi,
I have an e-bike with 7 x 12v 20ah batteries and an 84v charger. I stored the bike for the winter in a heated basement although forgot to charge the batteries throughout. Now I plugged them in overnight but nothing charged. When I measure the voltage using a multi meter, I get a 4.87v measurement on each battery. Does that mean they are no longer good or could it be my charger as it was sometimes finiky?
Thanks
