battery question

[rtwills]

I have a 24 volt trolling motor,and when I use it I notice when I get home that 1 battery is 75%-100% while the 2nd battery is like 25% or less....
Is this normal?
I just bought both batteries and even switched the cables on the charger so 1 is 2 and 2 is 1,and no difference
Also both batteries take a charge to 100%

RT- That doesnt sound normal to me, No offense but are you sure they are hooked up correctly? Are the fluid levels ok?

mine seem to drain at an even rate.

I'm pretty sure they are.
Pos of batt 1 to neg of batt 2
pos motor cable to pos batt2 neg to neg of batt 1
I have a 2 bank charger and when i switch charger cables the other batt. registers weak.
almost like it is taking batt. 1 power before batt 2

Yep thats the right connections. Not sure why it would do that.

When you switched battery 1 to battery 2 did the same battery location end up more drained? Is it the location or the battery?

I think you already aswered that.

I am sure you will get some others that will have more info shortly.

It could also be that one of your batteries is weaker than the other, just doesn't hold a charge as well.

I work with DC systems/batteries a lot and I can tell you this: Batteries are just like anything else, the are individually different and have their own characteristics to some degree. I have seen new batteries that will not charge well, or do not seem to carry much reserve capacity. To get 24volts, both batteries are connected in Parallel which is what you have therefore, the voltages will even out to 24volts (2 12volt batteries) What may not be the same is the current draw from each battery, it can be if both batteries are exactly even at 12volts, but more than likely they will not be exactly the same. This causes each battery to "cycle" different from one another...so in other words, one battery may be pulling more load than the other. If you have a multi-meter, I would check the voltage on each battery disconnected from one another. This will tell you which battery is holding the higher charge. There is not much to worry about unless the weak battery is so bad that is actually is causing a drain on the good battery. This will be noticable when you don't get much life out of either or the performance of your 24 volt trolling motor goes down. Hope this helps.

I said the batteries were connected in parallel above and I meant " in series" sorry. Hope you read this too
