True/False

I've alway's heard, that if you leave you're 12 volt marine battery or any battery on a concrete garage floor it damages or at least brings the charge down? Is this true? and if so why? Just wondering...Chuck

I heard that was true of older batteries years back, but with the newer ones, we don't need to worry about it anymore. I'm sure someone on here knows the real "poop" and will jump in soon.

Here's some reading. The trojan battery website says that it's o.k. to store or operate on concrete.

I don't store or sit mine on concrete either. Everytime I have to sit one down I go huntin a piece of wood. "They" told me a long time ago not to sit a battery on concrete and bygosh I don't. I've always wondered who "they" is, they seem to know an awful lot. But, I have read with the newer batteries it's okay.

For every thing you always wanted to know about batteries, go to this site:

See #10 for the specific answer:

10. WHAT ARE SOME OF THE MYTHS ABOUT BATTERIES?

10.1. Storing a battery on a concrete floor will discharge them.
A hundred years ago when battery cases were made of porous materials, such as wood, storing batteries on concrete floors would accelerate their discharge. Modern battery cases, made of polypropylene or hard rubber, which are better sealed, so external leakage, causing discharge, is no longer a problem. However, the top of the battery must be clean and dry. Temperature stratification within large batteries could accelerate the internal leakage or self-discharge if the battery is sitting on a cold floor in a warm room or is installed in a submarine.

Hope this clears it up,

Thanks again guy's I new I could count on you, I was gettin ready to call myth busters...and even though I do have several leaks in my boat it's not classified as a submarine yet...lol...Chuck

AndyG, that is the college course--YOU NEED TO STUDY HARDER!!

for those that dont or wont sit it on the concrete floor, curious do you keep a spare gotter key and shear pen in your tackel box, thanks

They need to offer a college course on batteries. That stuff is greek to me.

No more Greek than this : http://www.windsun.com/Batteries/Battery_FAQ.htm

(but, they all say the same thing ... no, sitting your battery on a concrete floor will not discharge it. But, leaving it sit for over a month, without topping it off with a recharge, will lead to a short lifespan !! )
