I'm not sure if my 12V 12Ah batteries are any good. I pulled them out of the case and put them individually on a 12V charger. They seemed to take a charge like normal, high rate at first and then drop to a trickle after a while. I then put them on a 100A load tester. Turned it on for 10 seconds and the voltage never dropped below 10. This tells me they are good, but when I put them in the bike I get only one light out of five and when I use the power it will not last for more then a minute.
Do you guys have any idea what could be happening?
