Ended up going to Wally World and picking up a new one for ~$80.  I'll make sure to disconnect it when storing the pod.

If a lead acid battery is completely or nearly drained and left that way for a few months, it is dead beyond any hope of reviving. After 'charging' such a battery, it might seem like it's okay because the voltage of the battery might be good, but it's capacity is almost completely gone.

Rather than plug up the unit periodically, I simply remove my batteries when we aren't using the Pod and place them on a Battery Minder #1500 all the time. It's temperature sensitive, so it doesn't matter that I leave them in my uninsulated garage. This way, I never have to worry whether my batteries are alright.

The other key to battery maintenance is checking the water level periodically, at the beginning and end of the camping season is good. The cells must be topped off with distilled water and nothing else.

The load test is good to find out how well it will hold up, but you won't do that test often.  The test at rest you'll do often to find the SOC.

Yeah I didn't think the interior meter was accurate, it was one light before and now it's 4.  I can take a meter out and check the voltage but the best way is to test the battery under load.  I'll probably end up in the battery section at the local Wally World soon... Cry

I'd go for the cheapest deep cycle battery, you just won't get your money out of the more expensive stuff unless you boondock all the time.

John, don't rely on the LED meter for anything other than the fresh water tank and the gray tank.  You need to take the resting voltage (3 hours disconnected) of the battery to figure out its true SOC.  Look up the Wind Sun Battery FAQ for a voltage chart and lots of other good info.

Back to my original question.  I left the pod plugged in on a 120vac 15amp circuit for two days and then disconnected external power.  Interior LED battery/tank meter showed 4 LEDs (full), not sure how reliable that is.  Then I pulled the positive lead from the battery and tucked the cable in the back of the box.  Will let it sit for a few days, reconnect the cable, and check to see if the charge holds.

As you know biggest bang and quality don't always coincide. Ref. China Bombs.

The Trojan T-105 is the gold standard. However, the Interstate GC2-XHD is also very good and may be more available. Sam's Club sells a couple of batteries at lower cost, but I'm skeptical. You get what you pay for.

Although Trojan are very popular, I chose to go this route and have been very happy:
