Digital camera Li-ion battery

triplemacs · Jul 4, 2009

I own a Nikon D70s which came with one rechargeable Li-ion battery (rated @ 7.4V & 1500mAh). Extra batteries run about $50 US. Nikon also sells a battery holder which takes 3 CR2's for about $13 US. If I put 2 RCR123a's & 1 CR123 spacer in the battery holder shouldn't I be good to go? Of course I don't want to fry my camera but I already have the RCR123a's & the charger, so for the cost of a spacer and the battery holder isn't this the same as the $50 battery?

I picked up a few extra batteries on ebay. These are not Nikon, but for Nikon. If I remember correctly, they were less than $10..

How are you going to put 123's in a holder designed for CR2's? The CR123's (or R123's) are longer and fatter than CR2's. If the diameter of the 123's fit then you shouldn't even need the spacer or dummer cell, two 123's is very close to the length of three CR2's (68mm vs 75mm).
If you manage to make two R123's fit you will still only have half of the original batteries capacity but two primary CR123's should have close to the same.

The two R123's will be a voltage match for the original but primaries may be a little low and you may get the low battery warning.

First, I don't own a Nikon- I own Canon.

Back in, oh, 2004 / 2003 I bought a whole slew of LI-ION batteries off ebay for my camera. Today marks the first time I've started having problems with them (And even then it might be the charger).

I own 6 clones and 3 originals. I have 3 digital cameras. In the first year alone I took over 15000 (15k!) digital images.

What am I saying? Buy the clones. They're worth it. Buy more than you need and keep them charged- toss'em in the bag.

I was actually about to look for rebuilding these or possibly finding a way to validate that they're charged appropriately- but all in all I paid about 9$ for 2 batteries + shipping- I've seen better deals since then.

Don't wait for spare batteries. Nothing is more annoying than missing a shot because your camera shut down.

(Look into that dual grip for 2x batteries too)
