Li-ion will be a problem as Owatta mentioned. Its a cool Idea though.

I am an employee and not a boss but I own 6 3.3 Hiltis and if one dies I just switch to the other and at the end of the day take the dead batteries home and charge them then.

I take care of my tools but even I do abuse them, batteries on the other hand are little girls though. You play to rough and they wont work again.

So if you want to be cordless invest in a couple more batteries.

Sometimes you can't charge batteries when they are hot/warm.. Like going directly from tool to charger.

Try fans in shade for a few minutes.............I think a ice bath is a bit extreme.

Good luck

With the ni-cad, the batteries will last longer if stored cool, i generally load 4 into a small cooler in the morning with a gel-ice bag. When one is low It goes back into the cooler and a fresh one grabbed out. Throwing a hot one on the charger is hard on them

Lith-ion are basically the same when it comes to storage and heat issues.

Since i started this system the batteries seem to last 3x longer

I had some DeWalt NiCad's that were failing. Places them in the freezer over night, and them thaw for a day. Worked line new again! Well, I got another year or so out of them. After that they were toast, and the freezer trick didn't work. This does not work with Li-Ion.

We keep the new Dewalt batteries in the shade, and let them air cool for awhile before charging.....now the XRP batteries, that was another tale. They would not ever take a charge when the battery was hot, and in the heat of summer, we indeed placed them in the top of the ice chest for half an hour to cool them so they would charge. The charger had a light that indicated "hot cell".

The Li batteries are a great improvement over the NiCads.

Opposite problem in the winter.

So, I live in Florida. It has been known to get a little warm here. :whistling
Been using Dewalt XRP's for about ever. I have at least a dozen charged and ready as we speak. Never really had any issues to speak of.

But if you are having issues, and putting them in a cooler helps, then go for it. It sounds like a logical thing to do.

I've got a dead one now. Gonna give it a try.
Even if I get another month, it's better than the paper weight it is now.:laughing:
Thanks.

Ya, I kinda abused my batteries last week- had to let them cool off before they would charge. An Ice chest is good, it will cool them faster, but just remember that the core is way hotter than the surface. Give them time to equalize in temp.
