[papercreters] Batteries on concrete (was: Re: just wondering)

We're getting away from discussing papercrete, but I'll join in the discussion anyway.

The biggest reason a lead acid battery discharges when sitting on concrete is because almost always whenever such a battery is sitting on concrete, it is sitting idle. People pull a battery out of a vehicle or some equipment, set it on the floor, and there it sits.

When a battery sits idle, on the concrete floor of a garage, on a shelf, in a shed, or buried underneath junk in the back of a pickup truck, most people tend to forget about it for weeks/months/ or even years. Neglect is very hard on batteries. You think concrete is hard? It's soft compared to Neglect. Neglect is harder than diamonds.

That's why Diamonds soften a woman's heart. Therefore Diamonds are softer than Neglecting her. It all seems so obvious now doesn't it? It's science!

Mohs' scale of hardness.

1 Talc
2 Gypsum
3 Calcite
4 Flourite
5 Apatite
6 Feldspar
7 Quartz
8 Topaz
9 Corundum
10 Diamond
11 Neglect

What? You don't believe that there is an 11 on the Mohs scale? Oh there is. There is. I think it was explained in a movie... Spinal Tap. ;)

Prove it to yourself by conducting the following experiment:
Find a person who neglects feeding their brain... and then see if they are hard headed.

You will find with a near 100% accuracy that hard headed people neglect feeding their brains.

What... uh... ahem... what were we talking about again? Oh yeah, batteries...


Getting back to the topic...




The best way to keep a lead acid battery in good condition is to follow several important rules.

1. Keep it charged.
2. Don't overcharge.
3. Avoid deep discharges.
4. Keep it filled with water.
5. KEEP IT CLEAN.

Number 5 is probably the one people neglect the most. Even a small amount of what appears to be dust on a battery can often be acidic residue. Acidic residue on the battery is conductive and provides an electrical path to discharge the battery.


By the way... those same 5 rules for taking care of lead acid batteries also apply to raising children. Think about it. :)
