Great price. Fast shipping. Works like the original battery. Thanks for a great replacement battery

Replacement battery fit perfect into my Acer A515-54 laptop. It charged up really fast. Easy to install.

Way better than the OEM version for this laptop. Unless you are watching a DVD movie it should last close to 3+ hours on a charge. The motor to turn disks can suck up a lot of juice.. Be very meticulous about following the instructions for conditioning the battery. Afterward, it lasts longer on a charge and should have a long lifetime as well. Of course the original battery the 1545 came with survived over a dozen years, most of it doing presentations. The main issue is that the laptops it's designed for are mostly obsolete. FYI- you can install a Widows 10 upgrade on the Inspiron, but it will slow down the system unless you have 8GB of RAM.

Battery works, but my laptop still not working on battery power. 😭 It was easy to install. Seems like it holds the charge well, not sure because my screen stays dark in battery mode. I left it on battery power over night and it was still around 65%.

Battery arrived as described. Battery fit into the laptop as expected. Laptop is working again without being plugged in. Satisfied Customer. :D

Needed to replace my battery in my Asus X555LA. The shop wanted to charge 69.00 and my son isn't home from college yet. With the old battery starting to expand inside the laptop and the top of keyboard starting to rise I had to make a move early. So I called Asus up. Being that this Laptop has no more warranty, Asus wanted to charge a $69.00 diagnostic fee. They wouldn't even give me the part number. Very sad after you purchase something from a company and just because the warranty has run out they want to charge you these outrageous prices to work on, but most of all not willing to give me batteries party number. Sad!!! I knew this wouldn't be a hard job, but wanted to double-check on battery out number. This is where Amazon customers helped with various questions I had from former purchasers of this battery. Thank God good people still exist that are willing to help others. Once confirmed that this battery was an exact replacement just made by a different company, I had went on and purchased this battery through Amazon. The battery was delivered fast, and the Amazon driver was very kind and considerate and made sure I was the one to recieve such purchase. This battery was very inexpensive as well compared to others. Hopefully this pays off for me in the long run. Back to the battery. Install was easy, except for the ribbon cables for keyboard and mouse. One thing to remember. Once you remove the keyboard cover, Do Not, if you can, pull up the keyboard cover all the way. Just pull it up easy just enough to get old battery out and new battery back in. Once you flip laptop over and you remove the screws, and then you flip laptop back over to remove the keyboard, the battery for this particular laptop will be in the front left corner, it's really easy to get it out and get a new one in. That's why I said I was able to do this without dealing with the ribbon cables that much. see Tutorial on YouTube!! You'll know why I didn't want to remove them. It's not hard, it's just tedious to get them back in place. I went and purchased the same size screwdriver tip that fit the battery screws which are 3, and it's just about 4 inches tall. Tall enough to replace screws without having to deal with ribbon cables for mouse and keyboard. Again see tutorial on YouTube. You will see why I purchased a shorter screwdriver, although the battery comes with the screwdrivers. So far battery is charging and will update how well it holds charge later. Other than that, battery fits for X555LA Install was easy if you have steady hands and able to deal with the ribbon cables then disconnect them but they are an SOB to reinstall back. I have big hands so it was a little difficult for me I just found the easier way by not having to disconnect them. When I received the battery all I had to do was put battery in, put the three screws back in the same spot. Snap back in keyboard. Turn over laptop, close and make sure everything is snapped back into place before you screw all the screws in the bottom. Please make sure you make a diagram as you're unscrewing each screw, stick it in like a piece of paper and just make a little diagram of the bottom of the computer because some screws are longer than the others. Again I will update how this battery works later thank you. Battery I received would not charge. Amazon sent another out and that one did work. Remember to always unplug laptop from computer before working on anything. Once new battery is installed, turn computer on and let battery run down to 2%. This will take some time so just let something like an internet radio station play. Please do not fool with battery while charging. Double check screws that are put in the right place and do not tight down hard, just snug is all. Once battery is at 2% then plug laptop up and leave it be for about 24 hours. Constantly check for any unusual odors. Battery may be leaking and if so, stop immediately and unplug laptop from wall. Wear gloves and safety glasses and throw laptop away. better to be safe than sorry. Remember before you start any project like this wear safety glasses and gloves. Remember to work in a well lighted area. Remember to unplug Laptop from computer before removing and installing anything hardware like a battery. If battery hasn't charged in 24 hours then the battery is most likely bad. And finally communicate with Amazon on any issues if exchanges are needed, Update: AC Doctor Inc truly is a stand up company. I had my battery fail after 10 months or so and they replaced it with a new one. These batteries are great because they come with a warranty. No questions asked! Update: Reduced review to 1 star. second battery from is company will not last past 88%. I tried to get answers. All they said is they refunded my money and replaced the other one under warranty. That's all fine and great but if these batteries aren't able to hold a charge hen they are useless. 88% and laptop screen shuts off. This battery last only 20 minutes unplugged from 100%-88% and then screen shuts off. Totally unacceptable. No wonder they warranty them for so long. STAY AWAY FROM THIS BATTERY. I have spent hours upon hours of trying to get answers from manufacturer. All they say is we refunded you and replaced battery. Again if they can't last past 20 minutes unplugged why bother. Please use another SELLER!!!!

Bigger than original but supposedly last longer. Sticks out rear of computer about an inch but other than that is working great. We don’t move laptop much so it doesn’t really matter to me. I wish I had known I could buy a new battery sooner. The original has been bad for many years. I will purchase again when this one stops charging. Cheap. We get about 4 hrs from a full battery

Well, almost. It's pretty good. Fitment was odd at first, but a a little jiggle, and it locked in. No need to force it, just alignment. Battery life is much better than the original; I get anywhere from 4-5 hours of life out of it. Very happy with it.

Arrived faster than guarantee. The OEM battery was in 3 plastic bags and swelled 2 twice it's size, distorting the keyboard so the touchpad was unusable. This battery is sealed within a metal box and cannot cause distortion. The battery comes with kit containing a snap-open tool and 3 screwdrivers. The battery fit perfectly within my laptop. I used UTube for a battery replacement video and the battery was easy to replace. Frankly, I was impressed with the whole kit! Unfortunately it lasted less than 2 months. The battery shows charged; but, the display dies when the power is unplugged and it cannot be started until the power cord is reinserted. i.e. the battery is defective. The warranty says 24 months; but, return was cancelled after 30 days with no option to return as defective. Stay away from this one!!!

Overall its good, i needed two of them so i can have one act as a spare while i have my laptop in the field or when i travel. It fits perfectly, and way cheaper then getting one from hp directly Two things though, first the lock switches are a bit tricky but they do lock in place when the battery is installed, and second thing the battery shows that its charged at 99%? I hope its a error from the computer and not the actual battery, I will be testing it using a volt meter to be on the safe side.

Well made battery, with instructions and tools to ensure a good installation process. Worked as expected in this laptop.

Battery works great, long battery life aswell. Easy to install into my laptop.

The battery works well. I would recommend.
