. . .Regarding the damaged batteries. I would use a hydrometer and check for any material floating in the acid. If none or not a lot I would give them a 2 amp charge for about 24 to 48 hours. Let them set for about 8 hours and then use a hydrometer. Again, this time checking to see if they are fully charged and about the same weight for each cell. If OK but not fully charged, again slow charge for another 8-24 hours and repeat the testing.
Thing about new batteries is that you are not to load test them until they have seen some use, (like around 3 months for starting use).
I feel Interstate make a good battery, for starter use. For hydro use you should never drain them, and should always slow charge them. You see a car battery is made to start the car, provide a small amount of amps to help the ignition system and they always have a charge going to them
If you drain your batteries and over charge them repeatedly, they will never last. You also need to rotate the batteries. Commercial grade batteries for golf carts, fork lifts, etc. are made to repeatedly charge and discharge.
Stay away from any battery you can't add water to. Never add extra acid (electrolyte). Buy a well known brand and never rebuilds. Of course the saying goes that the chain is only as strong as the weakest leak, so try to buy them all new at the same time, meaning this is the best you can do.
