Question: what dewalt batteries will this charger charge?
Document: Value for the price. Great for small workshop when space is at a premium. It is really great to have one charger to be able to charge all your dewalt batteries.
Ordered this charger in an attempt to revive 2 12volt PS130's I had sitting in my garage for almost 2 years. The Dewalt charger with it's conditioning charge worked wonders!! Batteries charge in less than 1 hour! Great buy!
This charger will not charge some Dewalt batteries that have L shape connectors. The Dewalt DC9310 charger has all the great features of this charger plus it charges both types of batteries (L shaped connections and straight connections).I hope this helps every one in their search for a great Dewalt Battery Charger.
Charges Black and Decker PS140 14.4 Volt Firestorm batteries. Much better than the stock Black and Decker charger as the tune-up feature of the DeWalt charger breathes new life into old batteries. Plus, the 1 Hour quick charge time is an outstanding feature.
Turns out this is a regular problem with the B&D charger. That's when I picked up this DeWalt charger. It couldn't revive my dead battery, but it certainly breathed new life into my other battery. It now holds a longer charge and seems to provide more power to my drill. I recommend you get this charger if you have the older pod-style tool batteries!
Not Your Average Wall-Wart Junk Charger:This charger actually has a line cord and plugs into a standard 120V wall outlet! It will charge Dewalt and Black and Decker batteries in the range of 7.2 to 18 volts. It also has a battery "rejuvinating" mode. It works and at the same price as a low-quality OEM replacement charger.
The charger for my Black and Decker 14.4 volt cordless drill failed, so I went to the internet to order a replacement. I found recommendations to purchase this Dewalt charger instead - it would charge the Black and Decker batteries quicker, and to a higher voltage, and had the capability to "condition" the batteries to prevent artificial voltage thresholds from limiting the capacity of the battery.
My old charger was broken. I looked on the DeWalt web site and also Batteries.com for a new charger. I tried Amazon. I found the same charger at a much more reasonable price and shipping was free. The price I paid was $30 to $40 cheaper. The charger worked as advertized, it took 1 hour to charge and it helped condition a battery that had a short use time. I now have full use of both my batteries.
I purchased this charger when I bought two new 14.4 volt XRP batteries for my Dewalt Cordless Drill. I was not sure if my old batteries would no longer hold a charge or if the charger was malfunctioning. The price was very reasonable and its ability to trickle charge after full charging as well as reconditioning rundown batteries is a plus. My old charger did not have these features. I used this charger to check my original batteries and learned they were beyond recovery.
I bought this over-priced Dewalt charger to charge my Black & Decker Firestorm 14.4v batteries, since all three of my Firestorm chargers failed after only a few months of use (one of them after 2 weeks (and can't seem to buy just the charger). Hopefully this one will hold up. The Dewalt charger is working like a champ for now. I would have given it 5 stars, but I'm a little angery at Black & Decker (who also makes Dewalt). So only 4 stars.
Answer: yes
