0 Stars!!! This battery is NOT for the all the laptops listed, my Acer 6920 has a 10v battery this one is a 14v! so i payed 32.25 then think the battery was bad send it back they send another 14v battery still doesn't work then it cost 10.51 to send it back again,I asked them to send a me 10v and they just send a email back and gave me a RMA slip to return it AND then they charge a 20% fee for returning items, plus shipping costs.([...]) so i only get back 25.76 and i'm out 27.51 dollars and still dont have a battery which is B.S. O and afterwords the item is still here on amazon with the wrong information after i informed them of the misleading information.

I have an Acer Aspire 5920-6864 laptop computer (BTW- I love it!) and have tried in vain to find a replacement battery. FINALLY success! I previously purchased 2 batteries that were supposed to be compatible with my computer. Not only would they not work the computer didn't even recognize they were installed so I had to return them. I was beginning to think I would never be completely cordless again but this battery works! yay! On a full charge I can get a good 3 hours. I know we want more but we always want more, don't we?

Well my daughters Acer Aspire Laptop died as hundreds of others ACER LAPTOPS HAVE DONE ONCE PURCHASED in the USA have according to all the blogs, help pages, help lines, Tech Pages, Product Reviews and Complaint Posts I found....We thought it needed a new battery, so we ordered this....then still no power, so we ordered a new AC Adapter....still no power, so we tried another brand AC Adapter, still nothing...so now after reading thousands of complaints on the net about Acers dying for no reason...I have found out that I need to charge the battery separately from the laptop and THEN put the battery in the laptop. Apparently there are default internal power settings that change on their own back and forth at random from AC to Battery until the battery is totally dead without any chance of turning on the PC to change the setting back to AC...Just ordered EXTERNAL BATTERY CHARGER - should have this week, and hopefully my poor kid will finally be able to use this POS that ACER calls a computer....lol Final Cost of HardKnocksLearning about $175.00. Oh that does not include the initial $548.00 price of the Laptop 18 Months Ago. Could have bought her another ACER POS for $248.00 @ Walmart...geesh..lol

After only 5 months of fairly careful and life-extending use, this thing has started to go from 55% to shutoff in about ten seconds. I have done everything a person can do to preserve the life of this battery since purchasing, and this just started happening out of nowhere. We have avoided overcharging it, it has been fully discharged regularly, it has not been exposed to temperature extremes.

It's a great price, and the delivery was quick, but I guess you get what you pay for.

I have an Acer 6930 whose original battery sizzled out for some reason and would only hold a charge lasting 5 minutes. After looking at some replacements, I bought this for an amazing $25 but wasn't expecting much. However, it appears to be working even better than when it came in new.

Should a new defect arise within a year, I'll update this review.

There is generally a one year warranty on these batteries. Mine stopped working after 7 months. It will not charge and my laptop shuts right off if I unplug it. I'm looking for the Vendor now to see what heis willing to do.

Delivery was great but thats it after reading the instructions on charging beforing useing and for the first 3 or so times you use it I went ahead. THE NEW BATTERY WORKED GREAT FOR ONE CHARGE THEN IT NEVER HELD A CHARGE AGAIN. THE RETURN POLICY WAS A PAIN AFTER YOU PAY FOR THE RETURN ITS NOT REALLY WORTH THE LONG HASSEL. AVOID YOU GET WHAT YOU PAY FOR AN AMAZON DOES NOT SEND THIS SO THEY DO NOT REFUND THIS.

Not as described. Did not work on my laptop. It fit into my computer but it might as well have been dead. My laptop recognized the battery but it did not charge. It had a 0 percent battery. Useless. Want my money back.

Needed a replacement for my Acer Aspire 6920. This was cheaper than buying name brand, and had decent reviews, so I gave it a shot. Very glad I did. On my 2 month of using this and it does great for what I use it for. The battery life doesn't seem to last as long as the Acer did new, but only by about 20 minutes or so. For the price, you can always grab two of these and not have to worry.

Product was exactly as described. Sometimes it seems to take a long time to charge but lasts just as long as the original battery. Great buy for the price.
