thanks Stuart.

I imagine i didn't kill it but after charging it to 100% as shown on the chargers' meter, with fridge running, I disconnected the charger from shore power, then reconnected it. Charger meter dropped to 75% charge. This led me to think that maybe my battery wasn't really charging to the 100% as indicated on charger. But maybe that's just a really sensitive meter I'm viewing. Like a very minor voltage drop in battery makes meter drop to 75% ?

Anyhow.....

Neil.
