Why does this battery read 56Wh and the titled information reads 48Wh?

I couldn't tell you why the titled information and the battery pic have different info. The battery I received is the one pictured with 56Wh. I have had it for a few months now and it works great, no issues whatsoever. I am using it for a Toshiba C655.

don't think so you old battery is 6am, this battery is 5am. probably wouldn't last as long

My new battery says exactly the same as you have described: Dell, J1KND, 11.1v, 48WH. Have had it for 3 months- fully charged is 3 hours.Happy with my purchase.Pat

I don't see a mAh capacity stated on the unit. I do see battery capacity stated as 44.4Wh which when converted to mAh is 12,000mAh.

It could be labeled as 2AH. Smaller batteries such as these are traditionally labeled in mAh.

The label says 1W. I plugged one into a kill-a-watt meter and it shows .02 Amp. (20Ma). Problem is it show this regardless of the switch setting or whether the LED's are on or off.... This unis has not been plugged in so the battery may be charging. I will leave it plugged in and update this info after the battery has had time to fully charge.

Since there are so many sellers, I can only confirm that the battery I received says 7800 mAh. Battery life was about what I had been getting from the 5200 mAh 6 cell that the thing came with (before that battery started to die).

Our battery has a number that ends in 54 - but is otherwise the same. From looking at our older battery my guess is that this is a lot number and the important thing is P100 since our other battery has a different number as well.

The writing on the battery does not indicate the number of cells in the battery. It states DC 11.1V, 48 Wh(400mAh)

Hi Matt, the new method for describing battery capacity has trended toward using Wh instead of Ah. To figure out the capacity in Ah, simply divide the Watt-hour rating by the Voltage. And even though these say 40V, remember this, straight from the B&D; web site: "*Maximum initial battery voltage (measured without a workload) is 40 volts. Nominal voltage is 36." So, 54Wh / 36V = 1.5 Ah (which is/was a common rating). I hope that's helpful. :-)

It is rated at 9.5Ah. which I believe stands for amp hours. The battery works very well.

These are 12 volt 35ah batteries. (Volts x amps = watts) So 12vx35ah = 420 watts max capacity per battery and 840w for the pair. If you want your batteries to last, do not discharge below 50% -- Therefore, with (2) batteries at 420 watts each, there is a usable 420w if you want your batteries to last a reasonable amount of time (500 cycles) - Your application may already have a low voltage limiter which won't let you drain below 11.9-12 volts which is about 50%

That is a dc rating for the power supply, not the battery. The battery is 10.8v 4400mah.

I noticed it doing this on my 75AH battery. But on my 35AH battery it does not do this, or it hasn't yet. I think it has to do with the battery size confusing the voltage reading. Batteries are still tricky to master. It's better that it's cautious during charging rather than brute forcing the battery into oblivion is my guess as to why it's quirky. What size battery are you charging? There is a range specified in the owner manual. I think 75AH is the upper limit. Maybe that's why it's doing that on the larger battery.

The battery I bought started off with 1185, not 1181. I have one word - don't.

my old battery has 10.8v, 4.7wh and 5200ma on it. I ordered by the HP part number and received a 'replacement' that has 10.8v and 5200mAH on it.

The one with 400W in the name is 400W. They make a 600W, maybe they copy/pasted the description without updating.
