Possible battery for a long lasting mod...

[bzlytbeer]

I found these when I was at Home Depot the other day. The size is a little bigger than the 186500 3.6 volt batteries, but this outputs at 4.0 volts, and the mAh is well over 3000 from what I recall. It says it can take over 2000 charges too.

The battery was about $14 , and the charger was about $11.

Can't find any dimensions for it, have you found any that you can link to?

The slim size of the Tek’s batteries means they fit into tools that ordinary AA and AAA batteries do.

should be a good battery....but they look longer

I've seen these in Home Depot. Would like to find the specs on the battery. It looks very promising.

So far this is what I found on Homedepot website...

36hours to charge, hope that's a typo
and for as large as it is, it's only 1500mAh

Unfortunately, I cannot remember all the specs off the top of my head. When I saw it, I knew it would be a good battery, but I really want something smaller. It is just a bit larger than a magnum flashlight mod. dedmonwakin - I think that may be a typo. I don't know of any battery that small that would require a 36 hour charge. My guess is either 36 minutes (pretty low) or 3 hours. Most of the batteries I have for tools take about an hour or 90 minutes to charge. Next time I am a Home Depot, I will snap a few pics, or buy one.

It does have potential. But honestly, your better off going with a 18650 2600mAh PCB battery for a fraction of the cost for that. The 18650 is 2.5 inches in height .5 inches in width. and 1000 recharge cycles 4.2v peak and 3.7 working (aprox 6 bucks)

According to the data, it's only 1500 mAh and as far as I can tell, unprotected by itself. So a mod may need to have protection incorporated.

Yeah, I don't think it's 36hours to charge, but I do notice that they sell a rapid charger for it seperately from the standard which charges it in 36 minutes stated on the manufactuer website.

Standard charger states, 5 hours.

...The 18650 is 2.5 inches in height .5 inches in width...

The 18650's are 18mm in diameter...so closer to 3/4 than 1/2 inch in diameter.

The standard naming convention for cylindrical LI-Ions is XXYY0. XX is the diameter, YY is the length. Both dimensions are given in millimeters.

So a 18650 is 18mm in diameter, and 65mm long and a 14500 is 14mm in diameter and 50mm long.

The actual battery dimensions do vary though.

I apologize, you are correct. It is 3/4" in diameter. And a non PCB is 6.5 or 6.6cm or 65/66mm long, add .2 or .3 cm (depending on internal PCB if cap ending)

I would be willing to bet it's a standard li-ion battery and they are just rounding out the volt spec. As dedmonwakin mentioned these batteries peak at 4.2 with 3.7v being nominal under load. They are probably just a different form factor.

When I look at the DealExtreme website, I see
