Battery Shut off and Storage Question.
Hi everyone. I store my trailer in the drive way. Therefor I can leave it hooked up to shore power 24/7. I have two 6v in series. I just got them yesterday and want to make the most of them. Sh...

An alternative: I have a box full of wall transformers that are cast-offs from broken devices or I've grabbed them when available. I chose a nominal 12V wall transformer. It's rating is 500ma. When unloaded, it's voltage is 16.2 DCV. I maintain a few auto batteries with this. If the battery has a voltage of 12.4 or 12.5, etc., I connect the wall transformer with a set of alligator clips. I monitor the battery until it reaches a voltage of 14 or so DCV. Disconnect, and the battery is charged. The length of charge procedure described varies by age, size of battery, and starting voltage. Typical duration is three or four days.
If I had more time on my hands, I'd break out a piece of perf board, interrupt the circuit with an appropriate IC, a few resistors and capacitor or two to make what essentially is a Battery Tender.
