Reconditioning a cheap 9 year old battery

Actually, the OPs Battery Minder 1500 (wall wart) maintainer has temperature compensation, you can see the pig tail coming out of the bottom and off to the right. I believe all Battery Minders have this feature.
The cheaper Battery Minders that look like a large power cube and the cube plugs into an outlet (no cord) do not have temp compensation.

But in a basement they would be fine.

Check post #9 above....

Here is their website, they no longer offer anything without temperature compensation (they did in years past, I had one, but that was a long time ago)

That could be. I have 4 Battery Minders and one is one of the old ones without temp compensation. Have not looked at their website recently.

Wife says any more than 4 and I would be hoarding Battery Minders.
