Few days ago, I used one of my deep cycle battery
with a 400 watts inverter
to run the TV and small appliances
during a power outage. The battery
worked awesome as it was suposed to. When the power got restored, I hooked the battery to a motomaster 12 volt charger
on the 2 amps circuit and let it charge for about 12 hours. After that, I performed a volt test on the battery but it was dropping dramatically fast! It lost
about 0.01 volt by second and it stoped dropping after few days at about 6 volts... What is happening? I never had such a problem with a battery.
By the way, the battery is a pretty common model, an Interstate HD24-DP
