Customer Reviews

This is one of those things where if you want something cheap that works well, and don't mind the size or old technology, it is OK.
To qualify that, it is 9" long, 3" thick, and 4" wide. That is a MONSTER for the features this thing has.
It should also be noted that this charger works on a timer circuit. With the switch set to "NiCd" it charges for 5 hours, and with it set to NiMH it charges for 8 hours. The charging is at a set rate, so that means in a given time, it can only put out so many mAh. (it varies by cell size, using different contacts at the center point of different sizes of cells)
Here's a quick example: If you have a AA rechargeable, and you set this charger to "NiMM" it will charge at 250 mA for 8 hours. That is a total charge of 2000 mAh. The problem is that modern AA rechargeables are rated 2400-2650 mAh. So this charger will not give a full charge. A 2650 mAh AA will only end up 76% charged, if it is fully discharged. You can start another charge cycle, but if you don't remember to pull the batteries out part-way into it, you will be overcharging them.
As a simple charger, it works. But battery technology marches on. Capacities get higher. My recommendation is to invest in a peak detecting charger.
I use a Multiplex LN5014, with a battery holder from Radio Shack. Of course that is a $75 charger, and requires a separate power supply. But I'm sure there are other options available in an inexpensive charger.

You don't want this charger, you want a "smart" charger. This is based on a steady charge rate and a timer. Maybe it's OK for AAs and AAAs (but even those take eight hours), but if you want to charge 10,000mAh D-cells, you get to unplug and restart this charger FOUR times over the course of THIRTY-TWO HOURS! 100% my fault for not paying more attention to the product I was buying, don't make my mistake though.
