Great Batteries! [Posted on 2008-03-13]
I am a professional photographer and my digital cameras and flashes swallow battery power, especially at weddings. I recently purchased a box of these Sunpak batteries and discovered that they fed my equipment completely and had leftover power to spare! I liked them so much that I bought a second box.
Here's a tip: Get a decent recharger. Most problems people encounter with rechargeable batteries is an inferior charger. Those "quickie" rechargers are junk.
Poor quality [Posted on 2008-04-02]
I've charged most of this package and none of the batteries charges to more than 2000Mah. The 2,650Mah claim is false on its face. These batteries are cheap and I'm not sure they're worth the price.
Really just 1900 mah cells??? [Posted on 2008-05-22]
These batteries seem to be rated rather enthusiastically. My LaCrosse BC-700 (set at 700ma charge / 350ma discharge) shows them to be a smidgen over 1900 mah. At around $30 / 20 cells they may still be a good value, but don't expect to see the stated capacity.
A second weirdness with these batteries is that they take 4 charge/discharg cycles to get anywhere near even the 1900mah capacity. The cells did all get an initial out of the box top-off charge and were then put into service in a handheld GPS that turned off in under an hour. I'd estimate <200mah for cycle #1. The rest of the cycles were on my BC-700 set to the above test test mode.

Low quality [Posted on 2008-08-21]
I bought these batteries from Amazon and they are very poor quality. Supposedly 2650mAh, the first four were broken in and tested. Three came in between 1850-1900 mAh, about 70% of advertised. The other one came in at 938mAh, 35%. I got Ebay quality from Amazon, which really surprised me. PS, I then tested four Energizers rated at 2500 maH and they came in at 2450. I used the La Crosse Technology BC-900 AlphaPower Battery Charger, purchased from Amazon too. It seems to be high quality. Not worth $31, not worth $3.10. Buyer beware!
Never Again Will I buy These [Posted on 2008-09-06]
Bought these for my Olympus digital camera. Not only did I get the least amount of use time with them, but they also do not hold a charge well.
After many attempts to discharge them totally and then recharge, I finally gave up and threw them away since they were worthless. Just before they died completely they were totally dead out of the charger and I hadn't even used them that much.
