What is the model number of the battery and can it be be easily replaced and upgraded?

The battery appears to similar to the ones used in a cell phone. It also comes with a charging cord, i just keep it plugged it all the time. It shows in the instructions you can leave it plugged in and it will charge to its capacity, then-not charge again until its needed. As far as easily replaced or upgraded? Easy to replace, yes. Easy to find that battery, i don't know. Upgradeable, not sure either. Sorry, this may be more info then you wanted and not the answer you were looking for. Hope it helps..

Not sure - ordered it for my sister 'a laptop and just ordered the same model number that was printed on the old battery.

Sorry to say I have never changed the battery. Its not written in the instruction sheet nor can it be found on the web. It just says battery is for back up.

Sorry, I don't remember my computer model number info. We have been happy with the battery though.

I´ve replaced the battery without any problem and it worked like a charm. I´ve never upgraded firmware versión before or after the change so I cannot confirm if there´s any issue with that. Good luck!

I forget the number, but just open it up and you can find the number, you can find the battery at anystore, I bought my at Walgreens, it is a easy battery to get.

I really don't know I don't think you can actually replace the internal battery or even if they actually sell it, I'm sorry I could not be of any help

You can always verify the battery via APC's battery selector - you need the exact model number - http://www.apc.com/tools/upgrade_selector/index.cfm

Several replacement numbers are listed on the battery I recvd, and hstnn-lb42 is not one of them. Hope that helps -

The battery is removable, so as long as you can find a similar version of it, you can replace it.

I am not the seller for this battery. I have purchased this battery once before in the past. I will be getting a larger battery as I already need to replace mine. Sorry I couldn't help much more than that!

The item has a built in rechargeable battery. No need to replace battery, but I do not know the model. That would be a question for the seller.

There are some guides online to tell you how to replace the battery. It involved de-soldering and soldering, so really only do-able for advanced DIYers. I tried and failed (but learned a lot about soldering on the way, so the $15 I invested was not completely wasted). Of course doing so will also void any warranty, so it's really only something that you will want to attempt if you have nothing to lose.

you may want to check with the vendor, I cannot remember but battery has been working fine.

It's an internal battery. Doesn't seem like it's one that you can swap out. I have had no issue with the battery and it seems to have a decent life.

I don't have an answer. Nothing in the instruction book tells anything about a replacement. Sorry.

Unfortunately I'm not an expert in these things but what I did is I looked at the sticker of of the backup, wrote down the full model number and did a search for a replacement battery for that specific model - took a risk and it works..
