I read the reviews & some say replacements don't have the power & run time as originals. Is this true?

I am VERY happy with the performance of this battery. It's like having a new drill. It holds a charge for a long time and had plenty of power. Glad I bought it.

I never did comparisons re: measuring output time vs. Torque vs. Voltage retention. Net assessment is good value for the price. Exact fit for drill and charger. Does what I need it to do, which includes getting additional performance frommy yellow drill.

I am an occasional user with a deWalt drill and both DW9106 and DW9118 chargers. I got a battery in July of 2014, and another in January of 2015. The first one lasted at least 6 months (or I would not have gotten the second one). However during the summer of 2015, they stopped holding charges very long, and now neither of the batteries will run the drill at full speed for more than 2 seconds. I am hoping that Power extra is reading this and can tell me what I am doing wrong.Given this experience, my answer to your question is, "Yes, there is a big problem."

Not in my experience. The replacement I bought was actually better than my original - especially @ the price.

They are the same. I compared the original with the replacement and found no difference.

I believe the specs for the product determine the watts. All the replacements should be the same wattage.

yes, I purchased one and it actually works fine. It has more cells than the original one so will be able to run your laptop for at least 1.5 times the original battery. Hope this helps. I bought this one for a relative at least a year ago and he's still satisfied with it.

Mine seemed to be an actual replacement. I didn't notice any significant differences, and it's worked fine ever since I installed it several months ago.

The original batteries installed with the phones were not holding a charge. Have hadno issues with these batteries at all (so far). Actually ordered more for a friend.She was frustrated and was going to buy new phones, and I told her I would order moreof these replacement batteries because they worked for me. Upon receipt, and installation,she has been completely satisfied, also. Hope this helps. Of course, you have to putthem on the base chargers from time to time to keep them fully charged...

Good question. I bought this battery replacement because it was considerably cheaper. Unfortunately, I must report that you most often get what you pay for. This battery did NOT hold a charge for more than 1/2 of the day, and has been replaced with the $40 version. The $40 version gives me a day and a half - A great improvement! I should note that I'm a pretty heavy data user and I'm sure that affects battery life considerably. In short, this battery is ok as a spare in an emergency, but not so great as a primary for moderate to heavy usage.

I am told no and the replacements are not rechargeable. They do have several years of life prior to failure.

Not replacable? Bummer! My unit is 2-3 years old and battery life is down to about 10 hours or less now. I had no idea I was expected to throw away a perfectly well functioning device for lack of a battery. This seems crazy!

Wattage not shown . Many customer reviews mention "not as bright as original" and several noted immediate or early failure.

Absolutely yes. I had somewhere hundreds hours of use and they working so good. It took me triple time to work with them then the originals.I positively recommend it.

I bought this one as the original didn't hold up. It is doing well for me. That is why they make replacements. If they really held up there would be no need to replace it.

Read the reviews and they should help you. They are supposed to be better than regular batteries.

When I was looking for replacements, I googled the exact model, for the battery and this can up as an option. I have had no problems. They worked perfdectly.

Hi. The replacement batteres are Li-ion rechargeable 18650. These are 3.6v, should be 3000mA.These are readily available with a charger through Amazon- I bought several sets and have had good luck.

the original adapter works for me. so it is able to charge this battery upto 100%, but the battery does not last more than 3 hours (almost like the original battery with 6 cells, with the 9 cells i was expecting longer charge time, now i wonder if it was due to the need for a new adaptor? or just that the battery was not of high quality, i'll need to cross check the voltage and amperage numbers before spending more on this)

I bought a replacement battery for my 18" Sony laptop some time ago and have been happy. I am not sure the replacement battery is the same as my model number is different. Even with setting the laptop for high performance I can get about an hour usage, when I could hardly get 10 minutes from the original battery. I hope this helps.
