Hi, I have a big Kinetik battery. Recently I took it out of the car to charge at home, I've charged it a few times doing trickle charge and all that, when the charger says it's completely charged I measure the voltage with the DMM and it reads high 13's v and after a while the voltage starts dropping fast and then stays at 10.64v .
1- Why is this happening?
2- Is there any way to fix this problem?
3- If there's no solution, Can I get money for this battery as is?
