Need some explanations on batterys

Postby KennyTheKangaroo on Sat Apr 13, 2013 11:59 pm

So kenny the kangaroo's new camera uses CR-2 batteries

So does it make a difference if its a 3.0 volt battery versus a 3.7 volt battery

kenny the kangaroo does not want to waste a camera by using a crap batter

First question i have to ask is... Does your camera use batterys, batteries or batter? Because that will let me give you the correct answer... :pop:

its the 3v. but the issue is that there are not a lot regargeable 3 volt CR-2 batters, but there seem to be more 3.7v batters with the rechargeable feature

If you use the wrong voltage you will break your camera. It is that simple. Now if you wanted expanded capacity, mAh measures that.

in that case, its going to be 3v batters nor not batters at all. thats pretty much what kenny the kangaroo was seeking to confirm. thanks

You can try the 3.7 volts. Most electronics have tolerance far greater than 0.7 volts.

A tolerance is built around the fact that it was built to fluctuate around its specified voltage. When you change that, you could fluctuate much higher than originally designed.

Also microprocessors expect certain input voltages and to skew that even slightly could cause it to malfunction.

No one is going to hook up a battery to a CMOS device wtihout going through a voltage regulator. There is too much variance on the battery over temperature and amount of charge.

Also, it appears that they are the same exact battery:

"Fully charged cell is 3.7V, but once battery is under load it will provide 3.0V (same voltage as regular non-rechargeable CR2 Litium battery). User should understand how Li-ion cell chemistry works."
