Hi I recently got a old style dilda from user Alexizupinhea. The laser is working very well, he gave me 2 cr2 "juice" batteries. They are 3.6v. They look like this: http://www.onlybatteries.com/webimages/images/15139.jpg

I didn't have the right charger so now I am using them with a "Since" 3v charger: Genuine SINCE Battery Charger for CR2-3V Lithium Battery (Silver)


How bad is this for the batteries, what are the effects? The only thing I have noticed is the battery's only last 10 minutes after charging. I have charged them with it about 4 times. Is this bad for the laser in any way?

Thanks for the help!

It's not bad for the laser, but it's simple common sense that it's really bad for the batteries.

There's a reason people selling this stuff always exclamate the point "Don't charge batteries with wrong charger". And it's not just to sell you an extra charger.

You're pouring gasoline in a diesel engine, practically.

Just get a proper charger and problem solved.

What voltage does it end up with after charging?

I have those batteries, but the CR123 type.

Ok I will, I know its bad for the batteries I just really wanted to make sure it wasn't bad for the laser.

Im not sure, i don't have a multimeter. Are the batteries lasting like 10 minutes because im using the wrong charger, or is this normal?

You won't be able to fully charge those batteries. 3.6 Volts are fully charged around 4.2 V. Those 3.0 volts are fully charged at 3.6 volts or so. It's only giving out 3.6 volts in the charger. You need a charger for a 3.7 volt, which gives out 4.2 volts.

Well, it's not really bad for the batteries or the laser. That is the correct type charger, but wrong voltage charge. Just as joeyss said.

Sorry Eud...
in this case that is not true...

His 3.6 volt batteries will never fully charge to 4.2Volts
with a charger designed to charge 3.0V batteries (which
will be fully charged at only 3.6V)..

If he was charging 3.0V batteries with a charger designed
for 3.6V batteries (which can be dangerous) I would agree
with you...

Oh ok, so you guys are saying it will just never fully charge. Thanks, ill probably get a 3.6v charger soon.

Still, Jerry, he's reducing the capacity of his batteries charging them that way. It can't be good for them. Right?

I'd advise against that and getting the correct charger as soon as possible.

Well, not really. If it was undercharged at just 3V then it could dangerous because the cells internals start to suffer damage and Li-ion cells doesn't suffer from the memory effect.

Those 3V chargers will charge up to the nominal voltage @ 3.6V so its still ok to use and the capacity will not suffer.

I have some Sanyo 18650s that require a 4.35V charge but I only charge them to 4.2V so I'm not getting the complete capacity they can hold.

at 3.6V resting, a li-ion cell is pretty much spent. You're trying to "run on fumes," (to continue the petrol analogy). overdischarging Li-Ions isn't healthy either, and you shouldn't assume that your driver will cut out at 2.6V loaded.
