Dell 1330/M1330 Compatible 4400mAh Replacement Battery for Dell XPS1330/M1330 + More

Pros: Considering the brand replacement battery costs 3 times more than this one, i'd say its a good deal.
Capacity is not as good as the original, but seems to be about 80% of the original battery. I get over 2 hours of usefull life out of this one, while the original got me just under 3 hours when it was new.
Batterybar shows 0% wear after 3 complete discharge cycles and some half cycles in between.

Cons: Fitting it is more difficult than the original - it takes some effort and tinkering to install, but once instaled it fits solid and doesnt protrude... seems to be an issue with the hinges.

Other: If you are willing to accept a little less battery life for a 70% price drop, get this battery.

Pros: Much cheaper than the genuine Dell replacement. Operating time around 3 hours in normal conditions with a balanced power profile on Windows Vista.

Cons: None so far. Only time will tell of this battery's longevity is up to that of the Sony-made Dell original.

Other: Recommended.

Pros: * The price is really good compared to other batteries at the same quality. * The battery can operate the laptop for2-2,5hours, (about 80% of the genuine one) which is great for this price! * Build quality is better than expected. All of the LEDs to check charge level works as it should * The battery weight is less than my old 9-cell. * Used it for two months now without any bigger problems.

Cons: * There are no other cons to this battery that the PC doesnt allways recognize this as a genuine battery, and therefore reduce its performance level, but if that happens, just take the charger in and out a few times, and it should be fixed! * I had to wait 2,5 months for mine, but they are probably restacked now, so should be alot faster for you guys.

Other: * If you need a new battery, and do not want to pay 3-4x this price for 20% more power in the genuine one, BUY THIS!
