Lenmar 2700 mAh rechargeable 1.2 V battery
After using these batteries on light use for about 1 year on my Pentax 6 MP SLR, the batteries have started to be useless for the camera, not even providing enough power to turn on the camera. Testing the batteries on a La Crosse BC-700 battery charger gives an average mAh of 2400 mAh - measurably below the advertised capacity of 2700 mAh. In Lenmar’s defence, the batteries were not initially tested on the La Crosse and also a usage history was not recorded for these batteries. Also, the advertised voltage of 1.2 V for these batteries is probably too low for the Pentax’s power requirements.
Potentially, these batteries are probably more suitable for use on Wii Remotes.
