This looks like a good deal!!!

The reason outlets near sinks have ground fault interrupters on them is because water conducts electricity to ground. Similar thing with water in dirt between battery terminals.

Thanks for making feel better about my battery maintenance or lack thereof.
I infrequently check my no-maintenance batteries and find the acid level low because they are no maintenance right?
We have all gotten sloppy with battery care compared to 40 years ago and we should not be.
Thanks for the reminder

That is why there really is no such thing as a maintenance free battery. Charging breaks down the water and produces H2 and O2. (why there is that warning about charging batteries). You don't lose the acid just the water, so add distilled water to maintenance free batteries and they will last even longer.

Looks like a really good deal.Thanks for pointing it out.

I just ordered one to hold a spare battery for my emergency generator.

The battery is going to sit on a concrete floor, and the advice is always to never put a battery on a concrete floor. For less than $9 the problem is solved.

I always love it when you guys in the more temperate climes say its cold it when its +30F

Ha! I love it when you guys up north call 80 degrees with 30% humidity hot!

It ain't hot until it it's at least 90 deg + with 70 % humidity and sweat is just dripping...:laughing:

Even when it's 90, a good shade tree feels like air conditioning when I'm mowing down front. I laugh when I hear the guys talk about cabs and heaters. I want a cab but it's not for winter. I want AC if I can find a place to mount the compressor. When we want more heat in winter down here, we open a door.

Sorry, the myth of not putting a battery on a concrete floor is just that. The battery case is plastic, and so is the battery box you're buying. Batteries do NOT lose charge through the case to the concrete floor/ground.
When I had my foreign auto shop I sold Interstate batteries for many years.

From homepower.com, concrete floors are a good place to store a modern battery:

--------
However, this legend is historically based in fact. The first lead-acid batteries consisted of glass cells that were enclosed in tar-lined wooden boxes. A damp concrete floor could cause the wood to swell, breaking the glass inside.

The Edison cell (i.e. the nickel-iron battery) that preceded the rubber-cased battery was encased in steel. Those that weren't isolated in crates would discharge into concrete quite easily. Later battery cases used primitive hardened rubber, which was somewhat porous and could contain lots of carbon. A moist concrete floor combined with the carbon in the battery cases could create electrical current between the cells, discharging them.

None of this is a problem with modern batteries — safe in their hard plastic shells. In fact, concrete is generally an excellent surface on which to place a battery bank. The electrolyte in a battery sitting on an extremely cold floor with very hot air around it could stratify, causing damage from sulfation; whereas concrete provides good thermal mass to buffer any temporarily extreme temperatures in the battery compartment.

Should have said, ever since history began it was true, then came plastics, and everything changed. So since about the 20th century, roughly, and the invention of plastics, the world of batteries changed.

Plastic cases don't allow discharge of the battery through a concrete floor.

I guess you don't know about AGM (Absorbed Glass Mat) batteries. I have been using them for many years.
