Question: Has anyone charged a 12v Ni-MH  (nickel metal hydride) battery in this charger?
Document: The charger works as promised, with all the optional batteries. I purchased this along with a replacement lithium-ion battery. The new battery charged in less than an hour and the Ni-cad battery also did a 'quick' recharge. Very happy with the results.
Was given a Dewalt Drill and battery (18 Volt) so we needed the charger for the battery. Got this and although we've used it only once so far it seems to be great. Charged quickly with no problems. Now we have a complete set and the fact that it charges other voltages will help in the future should we purchase a smaller drill as it can charge a smaller voltage as well.
I ordered this charger to charge my new 18V batteries as the original charger melted after not shutting off after only 4 months use. The charged charges a battery in 45 minutes, and it even charges my old 14.4 volt batteries, so I still use them and the old drill. This is a GREAT product!
There's a tune-up function on the charger if you leave it plugged in (for 8 hours) which I might try sometime, but for now I tried out my fully-charged battery and it works great with the drill! The cheap charger that came with the B&D; drill used to take 16 HOURS and you had to be "on the ball" to unplug it for fear of overcharging.
I was hoping for a charger that keeps the battery charged all the time by leaving the battery in the charger so it is always ready to go. I'm not sure if this charger senses when the battery charge drops to come back on to keep the battery charged, but so far seems to be doing the job. My batteries are new and not sure if they are holding the charge because they are new or if the charger is doing what I wanted it to do, or maybe a combination of both.
My old charger, the one that came with my DeWalt drill, would kill a new battery every two years if the battery was left on the charger all the time to keep it charged. When ever I would feel the battery when in the charger, the battery was always warm, always. After a battery was about two years old, it would not hold a charge anymore, the charger just cooked it to death.
If it didn't work, I can always use it as an extra charger, and it'll handle NiMh packs too. To make a long story short, the DC9310 was actually able to charge my dead DC9091. A test with a voltmeter showed that it charged to approximately 12 volts, indicating there were probably two dead cells inside the unit, but the battery was now usable again (albeit with less voltage).
by looking at the flashing LED red light you an tell if the battery is charged, there is a problem with your power supply, the battery pack is no good and one very intelligent feature if the battery is too hot or too cold the charger will let you know that it is not charging till the temperature of the battery is optimal for obtaining a good charge.As an added bonus this charger charges both types of batteries (L shaped connections and straight connections).
After checking B&D website, I noticed that DeWalt was affiliated. My theory? B&D 18v Firestorm cordless drill with post battery was really manufactured by DeWalt, but sales numbers were small. Just a thought, because my B&D 18v post batteries fit perfectly into the DeWalt charger and were charged up without problems in 1 hour. "Charging" and "Charging Complete" indicator light works well.
I had not used my B & D multi-use tool for months, and when I went to charge the batteries in the charger, the charger light never came on. Looking up a replacement charger I read the reviews on Dewalt's and decided to spend the $50 and hoped it worked. When I inserted the first battery the red light keep flashing, even overnight, but the battery was too dead. The second battery charged up successfully in a few hours and I was able to use the tools again.
Answer: yes
