I don't seem much different except for one big battery compared to regular batteries. I like the one I have.

No, they are not the same. The voltage is the same, but the batteries are intentionally designed to NOT be interchangeable.

As I recall this battery did not fit my T400i because of the shape where it connected with my lap top. They sent me the correct replacement and I had to send this one back. From what i remember, it was not that much larger than my other battery though. I hope this helps. Good luck. Donn

I noticed too the short battery life reviews, but then realized that these were mostly quite old reviews. Apparently the old model used the LR44 battery which had that problem. You'll see the current model uses a CR2032 battery, with a better life span. Also, the new reviews of this don't mention a problem that I see. I just received mine, and it is the newer model.

This battery will probably work for the T400. Am Amazon search for T400 replacement battery came up with the same battery from a different manufacturer. The great thing about Amazon, if it doesn't you can return it.

I believe the only difference is the color. The TRO480bs is silver. Try the Black and Decker website. You may find more info there.

helllo, not sure of all the differences, but I noted that 840638 charges in 3-5 hours, while 840045 charges in around 8-10 hours. That is on the product description section of each battery. Hope it helps!

I believe you are quoting the "Field Replacement Unit" number and not the battery part number. If your old battery is original lenovo, it should list two numbers. One is listed as "FRU P/N" and the Other is listed as "ASM P/N". Image brand lists the ASM part number. Some other manufacturers selling on amazon do list the FRU part number. If you go to the lenovo site you may be able to get the necessary ASM number (http://shop.lenovo.com/us/en/landing_pages/accessories/battery-selectors). You will need to know the model number of your computer (T400 in my case) and the "type" which is found in the middle of along number on the bottom (2764CTO in my case). JB

They are exactly the same with the exception of the bag on wheels provided with the LB6800prw. If you don't want the bag, the SE400 is the one you want.

I don't know the difference, but I can tell you to check the back of your battery for the serial numbers and codes and look for those code on a new battery. That is what I did and it works well and fitted perfect with my laptop 14R (N4010).

They both use the same replacement foils, so they shave the same. However, the BG2040 charges much faster than the BG2028 (1 hr to fully charge vs 8 hrs to fully charge). The BG2040 has a better battery life too.

Basically the LR44 is thicker than the LR1130. They both have the same voltage but the LR44 has more capacity. As far as capacity is concerned you can view it like a D size battery to a C size battery. Same voltage more capacity

Cannot imagine any difference at all. They are after market batteries and I have had pretty good luck with them. Just make sure the specs are correct.

Yes that's the only difference and you should go with the t- r42 because the price differential is not that great.

Are the the same size? Is there any numbering on the batteries in the laptop?

as long as the battery fits your model, you should be good upgrade. all you are getting is a larger battery storage, but the battery will still fit your model. no need to stay at 4400

Louis, DOES the pictured battery look like the one in your model 400? Not very scientific, BUT manufacturer does not share as much info as we would like!
