questionswhere's the best deal for laptop replacement…

My best real suggestion is to crack it open and identify the cells in it. Then replace the cells yourself. Any deal you get on a batter will probably be a used and non-refurbed battery that's as good as trash anyway. DIY with brand spanking new cells.

The only third-party batteries I have ever bought that were worth anything were for a couple of Powerbook G4s I had in the past. The batteries were actually marketed as superior to the Apple ones. Don't waste your time with a third party battery. I have yet to find a decent Dell-compatible one. One we bought felt funny when we got it, and barely held a charge. The other, it worked OK, but not as good as the original. Neither were worth what we paid, but both were less than Dell wanted for a new battery.

If you can't afford that (or don't want to!) @vinithehat gives the best recommendation. That being said, it looks potentially difficult, one thing I read suggested that you must maintain power to the circuitry if it is a "smart" battery to keep data from being wiped. Whether or not that was fearmongering by a greedy company, I don't know. An alternative might be somewhere like Batteries Plus. I think they might rebuild batteries, though I don't know if they do laptop ones.

Well! I guess I haven't missed much then! Thank you both for your responses.

No, you don't pop a battery open to replace the cells. In fact that's exactly what you're NOT supposed to do. The battery is NOT a servicable unit and playing inside it can only lead to unfortunate events.

Like another person posted, third-party batteries or refurbs aren't worth it. On occassion you can get a good one but more often than not you'll be looking for a replacement within a year. Do your best to buy an original battery from the manufacturer. It'll cost more but it'll last you (and come with) the original warranty.

Or stick it in the freezer over night and see if that helps. I've brought a number of LT batteries back to life (the ones that only hold 5-10% charger) this way. I make sure they are uncharged, wrap them in a plastic bag and toss them in a freezer overnight. Let them drop down to room temperature for a good number of hours (condensation is not your friend) and plug it back in. All of mine charge back to 100%.

I bought an extended life battery off ebay a couple years ago. It is still going strong. SunValley sticks out in my mind. Anywho, I paid $60 for it. An official Sony battery, non-extended was $150.

@perlgoodies: Hey, now there's something I'd never heard before! Interesting suggestion!

A USA based company

www.batterypower.co

offers warranty, free shipping and free returns.

average price circa 60US$

@vinithehat: I feel compelled to state why this should probably be avoided in a general sense for the masses.

1.) The Li-Ion gell in cells are very temperature sensitive and can vent highly flammable gases around if the soldering iron used bleeds too much heat into cell. Basically start worrying somewhere around 145-160 degrees.

2.) Accidently shorting the batteries will likely result in a fire at a minimum.

3.)Prying open a battery pack that is not designed to ever be opened can result in damage to the power management, safe circuitry, or temperature probe resulting in a probable fire or explosion.

4.) Huge fraud and counter fitting goes on with Li-Ion cells. China basically pumps out tons of counter fit batteries every month that are flat out unsafe to use.

5.) Also, some cells will deactivate themselves just with the heat from a soldering Iron thinking that a short has occurred because of the temperature.

I'll stop here ... but there are more.

@rlapid2112: There are also few US based producers offering "Better than OEM" replacements as well. MaxCapacity.co has some very high capacity 6 cell and extended packs and are also cheaper then OEM. Defiantly worth a peek especially if you looking to extend/upgrade the run time of an existing laptop.

15 month warranty ect...

can be bough at www.SafeBatteries.Com

@perlgoodies: The freezer trick can also be dangerous as well. By attempting "clean off" the anode/cathode inside the battery, one can cause some "derby" to dislodge into the gell and cause an internal short. Not saying that this is probable, but it is certainly a risk as well. In the end its basically just not worth the dangers for the 60 to 100 bucks.

There are a two US based companies that offer branded batteries that last about 2-3 years and pound for pound outperform oem in terms of safety and capacity. BTW sony batteries are some of the worst performers. They are safe, but just so over priced for what you get. I have a 2006 vaio and got maybe 1h 30 minutes using their 6 cell stock battery 4400mAh I beleive. I upgraded to 6 cell 5800 mAh/62.6WH battery and it jumped to 2hr 58 minutes! Ahhh finally I could last the whole trip to Florida without running out :)

@apfrehm: Apple flat out has the best mouse trap and builds some of the best batteries. That said better batteries do exist and generally fall into these categories....

4400 mAh batteries = very old technology/capacity... yes they are cheap, but who wants a battery that powers a laptop around 1:15 minutes and needs another replacement after 11 months

5200 mAh Batteries = Used by many OEM's and last about 2 hr with replacement needed around 2 years with light use (300 charges)

5800 mAh Batteries = State of the art advanced Li-Ion as of 2012. good for 500 charges with 3 hr run time between charges common. Check out http://www.safebatteries.com for some examples

@mazzman0: Thanks for the tip, I bough one of these batteries and I'm impressed. I got the 6 cell standard battery for my dell Latitude E6400 and get 3 hrs of run time in "Balanced Power" mode. "Extended Battery Life" mode estimates 4h 30min of run time which is much better then the Dell battery that came with it.

I would recommend this battery. I only wish I bough the extended 9 cell battery now I know they are good!
