When charging batteries, remember to keep an eye on all batteries every half hour, otherwise set an alarm based on time less than the estimated full charge time. I'm finding that the recharge rates vary and the battery charger light is not an accurate indication of the full charge or charging status. It seems these batteries reach a full charge and if not removed, will become warm to the touch. They will also give off a significant battery chemical odor, more noticeable when the charger lid is slid open. If any of these conditions happen, immediately remove the batteries because they're usually fully charged! I've tested three brands, metering each brand at various stages, both under load and not, and at various charging times.
