In general, this is something that must be considered when replacing cells on high-powered devices, like drills. These draw a lot of current and cells must be chosen which are capable of delivering the power required.

It may, therefore, be necessary to pick cells capable of drawing high currents. Note that a high Ah capacity is not necessarily a guide to how much current A it can deliver. You could do with a bit more discussion over voltage.

For instance a lot of Li-ion cells are 3. A nice help-oriented tutorial! Thanks a lot! I regret that I did not see it when my old electric beard trimmer went dead. To be more precise, its lithium ion battery went dead. But now I know how to deal with such battery mishaps.

There are little sets of pry bars that are readily available e. Very informative and handy tutorial. It helped me fix a defective power drill battery pack - when I disassembled to change the batteries I noticed that a soldering point was broken.

Fixed that and now works like new. Thank you! Could you even go for Li-ion? Reply 10 years ago on Introduction. It's definitely not so obvious I have to go back and reference info from time to time. I think there's also some misinformation out there. In most but not all situations, if the same type and all specs are the same just with a higher capacity ie, greater mAh then you can sleep at night and will have the added benefit of longer run times.

For example, if your drill lasts for an hour using mAh batteries, the same spec'd batteries with mAh will last 2 hours They take a beating and keep on going, and they're cheap. If I used the drill more or for heavy duty use I'd have went with these, but I didn't want to loose another good battery pack to dendrite crystals.

I was willing to give up a little 'ooomph' for longer runtimes. NiMH - Not ideal for most power tools. Still, I made an educated decision and selected these because I wanted a lighter duty drill that will last longer with a full charge. With that said, your application may differ and if I used this drill more I would have went with NiCd.

Probably the biggest thing to watch out for is your charger I have a trickle charger so it wasn't an issue, but not all NiCd chargers will work!

Although I infrequently miss the extra punch in the NiCd's had, the NiMh's still get my small jobs done. LiIon -I would not use these as a power tool battery. Great for low voltage and long term items With that said, there are exceptions ie, LiFePO4 which are more ideal for power tools, but for the price they just don't hold much juice. I'm not sure offhand how much of a punch they pack but my hunch is that they're less than NiMh It's an "experiment at your own risk" situation unless you are fairly certain about the details.

As always, Google can tell you more than you ever dreamed possible it's the ultimate rabbit hole. Too much heat directly on the cell will certainly limit capacity, and stands a minimal but not negligible chance to actually explode. This is an adequate step-by-step for using the "with Tabs" cells the writer referred to. If you just have the cells sans tabs, here are a couple tips: 1. Use the lowest possible setting for your soldering iron Try using non-braided wire around 16ga instead of tabs to connect each cell to one another.

Use a rotary tool to lightly scuff the surface of the cells and also the surface of your connecting material. Don't mix old cells with new cells; your battery is only as good as its weakest cell!
