Title: Compatibility problem with Canon SD870 IS
Review: I recently bought 3 of these batteries believing that they were truly equivalent to Canon's NB-5L for my Canon SD870 IS camera. All of the 3 batteries exhibit the same symptom: Even right after being fully charged, it will cause a "Change battery pack" message on the camera. After re-inserting the battery, the message will go away. This has not happened to my Canon NB-5L battery, just these Lenmar batteries. Another problem: they don't last as long as the Canon battery.
Is the review positive or negative?
