Hobie Bait Tank 6Volt Battery Question

Which leads me to believe it is the battery.
When fully charged and allowed to rest for a day, the standing voltage is 6.2volts. I believe this is too low.
If you have a few minutes, could you check the standing voltage on your fully charged 6volt battery with a meter and let me know what the reading is? Trying not to waste $$ on a battery if that's not the issue, but your findings will confirm or debunk my theory. Thanks so much.

I had the same problem, started using my newer XL tank battery(same size) in my regular hobie live well and the problem went away, ie the older battery does not hold a charge for as long. Answering your question, I just put the volt meter on the old, new and charger with the following results:

7.0 Volts for the old battery that only lasts 5 hours
7.0 volts for the charger
6.8 volts for the newer battery that lasts all day

Conclusion - just because a battery will charge to a higher voltage does not mean it will last longer. The older battery must have some kind of memory damage, thus it discharges faster.
