Ownership verified by DX Overstated capacity
Posted by KreAture on 4/9/2009
Involvement: Expert (understands the inner workings) - Ownership: more than 1 month

Price: starstar
Ease of Use: starstarstar
Build Quality: starstarstarstar
Usefulness: starstarstarstar
Overall Rating: starstarstar

Pros: + 50mm long, very nice for fixing DSLR battery packs.

Cons: - Only 950-1050 mAh at 200mA discharge. Way under the rated 1600!
- High internal resistance, lousy at 2C discharge.

Other Thoughts: These cells would be ideal for fixing my old DSLR battery packs by fitting new cells in them. However, they are very poor on capacity vs what is rated so will be pretty much useless. I cycled all the ones I ordered multiple times on a Triton charger at low current and they still only deliver 950-1050 mAh. In fact, most of them are in the 880-area.

Bottomline: If DX comes with a new type of 18500 cell, get that instead.
