hey guys i got a i1480 laptop and the battery is dead, it came like that with the computer, i was wondering what is the standard battery life for one of these, the battery is a FRU 02K6647 and are there any other batteries I can upgrade too, so it will have an even longer life.

The standard battery life of the battery that shipped with the computer should be listed somewhere in the hardware maintenance manual which can be found on the messageboard's FAQ.

i looked in that whole document and could not find it, anyone got a page number, or super sure its in there because i can find all the specs for everything else just not the battery life.

The average life on the original batteries, if you can't find the specs, can generally be assumed to be in the ballpark of 2 hours.

ok thanks, thats pretty long, one other question, anyone know of anything i could do to try to revive the battery, i found one thing on a web site that said and i quote

"Battery Revival:

The batteries on laptops are often a problem. Most people sit their laptop on a desk and use AC power, so the battery usually suffers, resulting in a chemical ‘memory’, which gives them a life of about 3 seconds under load. The batteries in my donor laptops were both made in 2000, so I had to try and revive them. If you have any NiCd or NiMH batteries that won’t hold their charge, you can often revive them. This is not a new concept, but here is my recipe for reviving rechargeable batteries:

1. Discharge the battery as much as you can.
2. Place in a sealed plastic bag.
3. Place the bag in your freezer for at least 24hours. Overnight is sometimes enough, but I leave it about a week.
4. Take the bag out of the freezer and leave the battery to return to room temperature. Make sure you wipe off any condensation from the battery contacts before you use it. I just leave them in the sun for a few hours.
5. Fully charge the battery, then run it down again, as low as you can get it. Repeat this charge-discharge cycle a few times, and see if you get a longer life.

Your mileage will vary, but two of my 5-year-old batteries are now useful. I get between 2 and 4 hours from one of them, depending on the load on my laptop. You can do this with cellphone batteries, or batteries from lots of other gear."

what do you guys think about this? i think i'll try it, my battery is 100% dead so i can't really hurt it anymore.

I have tried this method on over 2 dozen 600/600E batteries....I have yet to get it to work.

I think the method was designd for NiCD and NiMH batteries. If you leave a LiION in the freezer for a week, you might kill it.

I believe that you are right, but the article that I read (way back when) had said both NiCad and Li-IOn.
