Windows 7: Question on buying a new Battery...

Question on buying a new Battery...

Hey everyone I am buying a new battery for my Hp Compaq 6735s Laptop.

The standard battery I got with the laptop is: 10.8V - 47 Wh - 4200mAh
The one I am looking at buying is: 10.8V - 5200mAh
Battery for Hp Compaq 6720s 6730s 6735s 6820s 6830s NEW - eBay (item 230508215312 end time Aug-08-10 20:52:22 PDT)

They don't specify the Wh (Watt Hours).


The model code I have on my battery is: HSTNN-OB51 451086-3632

Can anyone tell me if that would work with my Laptop? Like will it hurt my laptop if it's a 5200mAh instead of a 4200mAh?

The battery looks exactly the same as mine but mine weighs 339g that one is 479g. Mine is dead so I guess it should be less right?

Thanks heaps for any help!

4200mAh means 4200 milliampere hours (or 4.2 ampere hours). 4.2 X 10.8 gives about 45 Wh. I can't answer why it's not 47.

The 5200 mAh should give you 56 wH. It's not unsual for third-party batteries to have higher ratings than the manufacturer's battery, as well as being cheaper.

The eBay battery weighs more than the OEM one because it has more stuff in it. Batteries may not lose weight when they die.

It should work OK with the laptop. Some people shy away from third-party batteries because they are afraid that their compatibility claims will be false.

Should be OK, but the choice is yours. You may not get a reliability report from someone else who bought exactly the same battery.

I'm sure it will work, but I tend to shy away from ebay these days. I would recommend buying one from Amazon. I found the exact battery you have now for about the same price after shipping as the one on ebay, but it comes with a 1 year warranty and (for some unknown reason) a free USB extension cable.

Petey,
When it comes to hardware I always buy locally so if something goes wrong I can take it back and get the issue resolved quickly.
Software is another story as I will buy that from Ebay or wherever.

That's pretty much why I don't buy anything from amazon. I'm not from America. Or I would possibly buy everything from Amazon because it's usually cheaper than Ebay. Unfortunately for me I'm from Australia.

If you guys are pretty sure that the one I will get from China on Ebay will work then I am more or less happy to get that one. I messaged the seller and he said that they work for HP in China and they sell replacement batteries which are the same as the ones you get with your laptop. If it doesn't fit or work he said that I could send it back and specify which one would work and they would send me the right one.

I think that's good enough for me. Hopefully it will work first time, and for $40 and free shipping it's not much money.

Thanks to everyone for your suggestions. I just wanted to know if this battery would potentially burn out my machine. Other's told me that more powerful 14.4 V and 87 Wh batteries would cook my laptop even if they fit my machine.

Yeah. I think that using a battery that doesn't match the original voltage might kill the laptop.

With any luck, it couldn't arise. I hope that a battery with a different voltage wouldn't fit, physically.

I think Amazon has a New Zealand site. My main point was that batteries should last at least 12 months. The battery on ebay has no warranty, so what are you going to do if it konks out 3 months from now? But then again, compared to what OEMs charge for new batteries, 3 months for $40 sounds worth it.
