Title: Versatile, but Not Smart
Product review: This unit is versatile as it will charge several sizes of batteries, BUT I was surprised to find out that it charges batteries for a fixed time of 3 hr or 5 hr for NiCd and NiMH, respectively (at 500mA)--a semi-rapid charger. The new NiMH and NiCd battery chargers (not this one) generally use some delta-voltage-current-somethingeruther and a few other newer techniques to charge batteries only up until they're full, then they trickle charge them. This Energizer model seems to use "old" technology to charge batteries. It doesn't matter what size/capacity/charge level, it charges them all for the same fixed amount of time. I found that it charged barely-discharged NiMH batteries for the same fixed 5 hours. To me, it should not run so much extra current through them unnecessarily. I guess it does the job, but I cannot find a "smart" battery charger that would charge the other sizes.
