User Ratings and Reviews
5 Stars N/A
Received the laptop battery very quickly. Put it in my laptop and it has worked perfect so far. It has a lot of charge time usuage without the power adapter plugged in. Great battery. Worth the money.
5 Stars Better than original battery
Original battery lasted about a year, it was a long life the same as replacement except not from Dell. The replacement was installed on 6-24-2007 today 5-6-2009 it only lasted about an hour so decided to order another from Power_Direct. This battery has worked twice as long as original and is still working. Ordering a new one today.
5 Stars Battery usage instructions
Just a little tidbit for everyone using laptop battaries(specifically LI-Ion)
Most battaries that favor a constant charge and recharge capacity work in two different forms. Your standard Ni-Cd or nickel cadmium battery is a slow drain slow charge type battery, a complete drain and recharge is a standard that most of us know. Not the case with Li-Ion, the lithium battery, and newer Metal Hydroxide batteries work better and last longer using the 100-40-100-20-100-40-100-40-100-20% recharge plans. On your initial charge of 100% charging you let the battery drain to 40% and then recharge to 100% and then the second depletion to 20% and back to a full recharge cycle. This helps maintain the battery condition and in some aspects the “Brain” of the battery so to speak is set in motion and maintains battery health througout time.
I myself thought the cycle was complete depleation of the battery on each recharge which actually shortens the life of the battery.(learn something new everyday)
Another item to remember is that when you plug in your laptop, and the indicator says fully charged, the battery is still being used in most cases and recharging. A good note is to remove the battery while in use of a power outlet and set aside until going mobile. This will also help prolong the battery. Hope this helps anyone who may be having to replace batteries often.
(P.S.) also good for cell phone usage (have had my phone for 4 years with no problems in keeping a full charge of battery life for at least 2 days, havent replaced the battery yet)
Enjoy 
4 Stars Solid Replacement
Although this is clearly not an OEM replacement, the battery worked fine and I got 4-5 hours of time on it mostly playing a video game. I can’t give it 5 stars because I have only had it for a month.
1 Star Useless product
Bought this battery 2 weeks back, worked fine for a week, now it’s completely drained off. Can’t recharge it at all. Will have to call Brainydeal for a replacement.
DONT Buy this product !!!!
