DeWalt DC9091 XRP 14 4 Volt 2 4 Amp Hour NiCad Pod Style Battery

Step up to the extra power of the DeWALT14.4-volt XRP battery pack. This high-capacity NiCad (nickel cadmium) battery delivers 40 percent more run time than standard NiCads. That means you can work longer—drive more screws, bore more holes—and spend less time swapping out and recharging batteries.

The XRP pack, which stands for eXtended Run-time Performance, will fit all of DeWALT’s 14.4-volt cordless tools and chargers, except its Univolt tools. Finally, remember to recycle your old batteries. –Joseph Truini

What’s in the Box
One rechargeable 14.4-volt XRP NiCad (nickel-cadmium) battery

4 Stars Dewalt 14.4 volt battery
The price for these batteries was very reasonable compared to the full price. I would recommend these to anyone needing new 14.4 volt Dewalt batteries.

5 Stars Vince
These XRP batteries are a lot better than the original battery if your drill was made after about 1999. My original batteries only lasted about 3-4 years on my new drill (purchased 2004). I have a Dewalt 14.4V I bought in 1994 and still use the original batteries. One word of caution, the XRP batteries will not fit in the older drill case whether on or off the drill because they are larger. The older case has a more molded appearance on the inside and is double wall plastic.

5 Stars DeWalt 14.4v NiCad replacement battery
I was disappointed in the DeWalt 14.4 volt batteries that came with my drill/driver. When one totally died during a project I sent my wife out to get a replacement battery. She returned with a NiCad version which I loved. It holds a charge extremely well and lasts much, much longer between charges. I was so impressed that I got a second one and recycled my remaining (operable) original battery. It makes using the drill much more practicle.

5 Stars DeWalt Battery
There’s not much to say it’s a battery, but so far it seems to be working great

5 Stars Great power, high output
Bought a set of DeWalt tools, which included two XRP 14.4v batteries and a charger over four years ago. I didn’t really use the set much until the last two years, when I suddenly had a couple of backyard projects. These batteries pack quite a charge, and provides plenty of power and duration, especially for the reciprocating saw and trim saw. Unfortunately, last weekend one of the batteries died out and wouldn’t take a charge anymore (it’s been on the wane for a couple months before that). I’m hoping the other one will continue to work, but now I’m stuck with only one working battery. I came nowhere near the advertised 1,200 charge/discharge cycles, so that was disappointing.

I’ve had these units for more than four years, so I can’t complain about one dying. While I agree that these batteries are excellent, and should be priced accordingly, I’m not sure they need to be quite that expensive. There are companies that’ll rebuild the battery pack, typically with longer-lasting sub-C cells, for less than the cost of a new one (but admittedly not by much). Based on trade reviews, the rebuilds either meet or exceed specifications, and I’m leaning that way not so much for the cost savings, but for the extended runtime.

So, in summary, these are absolutely great batteries. The NiCad technology is proven, dependable, and is suited well for high drain devices such as power tools. However, given the relative cost and simplicity of manufacturing a unit, you should be able to get more performance for less from a reputable battery rebuilder.

EDIT (12/04/2009): Bought a DeWalt DC9310 charger DeWalt DC9310 Heavy-Duty 7.2 Volt – 18 Volt 1 Hour Charger to replace DC9116 charger. The DC9310 was able to charge the dead DC9091 to ~12 volts consistently, indicating two dead cells. Battery is now usable again, but at 12 volts. While not ideal, it was good enough for me to effectively operate all the tools, thus extending the life of the battery.

5 Stars Breathing life into a old phone
I had this same battery for the past 3 years on my 6 year old phone. When the old one didn’t hold enough charge, I just ordered the exact same replacement. Its been working flawlessly since I installed this new battery.

1 Star Disappointed
bought this a few days ago, installed the battery (ER-P511) last night so it could get a full charge, and nothing, does not hold a charge at all. bought for a KX-TG2730 Cordless phone. Put the old battery back in and phone works fine, but of course the old NiCad battery GE 86400 is quick to lose the charge. I never return anything, but I have to return this, hope they dont give me any problems, I have been saying good things about Amazon. I will post a update on any problems.

UPDATE, I returned the battery and received a refund with no problems, not sure why the battery did not work for me. This update is being written well after the return was finished, today’s date 7/30/09.

1 Star Caution: Shipping Rip Off
Price is attractive, battery is excellent. BUT shipping charge is per battery. If you only need one battery, fine, but when the shipping charge at checkout is needlessly excessive, it tells me to Never buy from this seller — and to take the time to do this write up.

5 Stars Excellent replacement battary
I have used similar battary for more than a year and it is very long lasting. It doesnot have any memory effect like NiCd battery so lasts very long in every charge. I am very happy with this battery.

5 Stars Outstanding replacement batteries
I replaced the batteries twice in my phones previously. The new batteries lasted a while but still intermittently dropped the connection. I replaced the batteries with these Lithium Ion replacements (old ones were NICAD) and all the connection problems disappeared. The batteries life has increased quite a bit with the stronger battery (more amperage). I’m extremely satisfied with these batteries.
