I have a smaller (20Ah 16CL-B) flooded cell battery for a jet ski that seemingly died after being charged.
I pulled the battery out of my basement this spring to put in the jet ski and did an initial top up (about 4 hours) after the long winter. Battery charged up great and jet ski started fine. The jet ski then sat for 5-6 weeks, and I figured I'd top up the battery again to be sure before going on a trip. Hooked it up to my Noco charger/maintainer and let it go for a few days before we left. The charger said it was fully charged and good to go. To my surprise it wouldn't even crank the engine anymore. Put a meter on it and it read 12.5 volts resting, but as soon as I tried to start the engine the voltage would tank to 5-6v.
I am at a loss honestly. The battery isn't that old, 3-4 years. Always taken inside in the winter as well. I am a little lost as to how it could go from working fine to a literal lead weight in 5-6 weeks. The acid is at the correct level, the plates appear fine. I am getting a little tied of buying new batteries all the time. I just seem to be having bad luck with batteries in all my toys.
Any thoughts or ideas to prevent something like this in the future? Any way I can possible recover the battery?
