These were replacements for previous batteries of about the same age....bought both sets from Walmart......what am I doing wrong..when not in use I turn the battery switch off..perhaps a new brand of batteries is in order
Your disconnect switch may not be totally disconnecting the bank from all draws. A simple test is to pull the neg cable(s) the next time and monitor the resting voltages daily or weekly.
Running the engine is not usually done long enough to provide sufficient charging so that the batteries can hold a charge for a whole day, even if disconnected. You will need to do the disconnect test to observe this.
