Currently my batteries are not being chanrged anymore, I have replaced them and they work for awhile but then go dead. I have tunred everything off and still they do not seem to get charged when plugged into the shore power connection.

I can here my invertor huming when plugged into the shore power, so my question is, how do I know whether my invertor is working correctly or if that is actual problem.

It is an older 15amp power invertor, what should, I have a starter battery model 800(cranking amps) and an 110amp deep cycle battery from West Marine.

What invertor would you recommend...?

And how could I make sure that the invertor is the problem...?

thank you,
