Ex-Pro CRV3, CR-V3, CRV-3 High Power Plus+ 2 Year Warranty Replacement Lithium RECHARGABLE - Li-on Digital Camera Battery for Pentax K100D, K100D Super, K110D

This is a bit pointless. How can you review a battery? So far it has performed satisfactorily but I will only know if it is good after several months or years.

Bought these for an older Pentax K100. works well.

Just fine

What a fantastic product. I've been guddling about with rechargeable AA NI-MH batteries for the past couple of years and they're almost impossible to get to retain a charge. The CR-V3 are absolutely brilliant. I've taken over 600 photographs and the cells still do not need recharging. Buying these has transformed my photography. I can now go to a commissioned shoot or out on a wildlife trek with real confidence that my camera will still be operational hours later. I bought a further set for back up but so far haven't needed to use them. Highly recommend this product and this seller, really pain free transaction with very fast delivery.  Ex-Pro CRV3, CR-V3, CRV-3 High Power Plus+ 2 Year Warranty Replacement Lithium RECHARGABLE - Li-on Digital Camera Battery for Pentax K100D, K100D Super, K110D

After years of rechargable batteries letting me down I decided to go for the Lithium Ironoption, this product comes with a car charger as an added plus, so you need never be without power, Highly Recomended.
