Pros: Basic accessory
Cons: Poor, but very expensive

K-30 accessory. But I use the bh109-aa battery holder with Sanyo Eneloop 2000mAh AA batteries - which it is unfortunate that it can not be used for newer cameras.

Pros: Lasts through many recharges
Cons: Massively overpriced

The mere existence of this item puzzles me. I have some of the AA battery adapters for my K-r and I get a much better life from a set of good AA rechargeables, so why didn't Pentax just make the K-r so it took those AA batteries directly? Very odd.

OK, it exists, so is it any good? Well I've been using mine for years and it it still takes a full charge, powering the camera for pretty much the same number of shots that it did when it was new. If it's capacity has dropped, it hasn't dropped much. In addition, I can charge it and leave the camera in the cupboard for a few weeks and it will still pack a charge when I get it out, and that's not true of all rechargeable batteries. All in all, it seems like a quality item.

The price, however, is outrageous. In the UK at the time of writing it's 59.99, which is over $93 US at today's rates. I can buy a lot of low-self-discharge AA batteries for that money, and a set of 4 of those lasts longer. Lower the price to 10.00 or so and it might be reasonable, but 59.99? Pentax can keep it, when mine dies I'll just use AA batteries.

Pros: Long life

Battery often holds charge beyond its posted rating. After over a year of use I haven't noticed a significant drop-off in performance.

Part of K-r kit. Battery life is good, often exceeding the CIPA rating, but had wore down somewhat after 18 months of use.
