Before I buy a new battery...

    I just wanted to make sure I'm getting the best one! I have a Dell XPS M1330, and the battery life is tragic. It would literally last about 5 mins if I plugged it out right now.

    I thought I may as well get as high a capacity replacement as possible. So a quick Google shows that the 7200mah seems to offer the highest capacity. Besides the extra price, the main disadvantage is that this battery doesn't sit flush with the back of the laptop. The 6600mah also extends out, but the 4400mah shown on the same page is flush.

    Do the higher capacity batteries offer a significantly higher charge time, and will that same high charge time generally reduce at the same ratio-rate as a lower capacity?

    The 7200 is on ebay for only ~€40, so I'm probably going to go for that unless you guys would advise otherwise?

    Thanks very much for any help!

    Get a legit battery. I saw one of those aftermarket Dell batteries split open at the seams after the first charge. Li-ion cell swelled right up from overheating.

    Now im sure they don't ALL do that, but considering that you may at some stage leave your laptop plugged in overnight etc, its just not a good idea to be going with aftermarket batteries, they're a hazard. A Dell battery will have to pass CE regulations and have various safety features etc....with these aftermarket yokes, they can just shove a couple of big li-ion cells into it and call it a day. Ive seen the circuitry on some of them and its pretty dodgy.

    I agree, i took a part a fake dell charger bought on ebay from china and it looked like it had been soldered together by a four year old. Shockingly bad, despite looking the part from the outside.

    Thanks for the replies. Given that the ebay seller has close to 100% feedback after around 17,000 sales I would have thought the product would be up to scratch?

    Average person buying something on ebay doesnt know anything about electrical safety, and most would just give positive feedback as soon as they get the item anyway. You'd never know if it gave trouble later down the line.

    Its your call. I love a bargain as much as the next person, but there's some things that I wouldn't skimp on, and laptop batteries would be one of them. I got my Dell battery off an ebay seller called black-cat2, and while it was expensive (~£80), it was cheaper than buying from Dell and was a legit battery.
