This replacement battery pack is manufactured to OEM standards and works great. The actual batteries themselves are apparently Sanyo lithium ion. This is a fresh battery with a manufacture date of 6/2025, and 1 charge cycle. This was actually the second battery shipped; the first one also looked in perfect condition, but would not charge. They shipped out the replacement immediately and it arrived in a couple of days, without waiting for the return. The first one just has to be sent back at their expense within 30 days, e.g. dropped off at any Staples.

Came with everything I needed to replace my laptop battery myself. It worked the first time and has been working for many months exactly as expected. Well done product.

Do not buy this, it is a piece of trash, it has been 5 1/2 months since I installed, and the battery is dying. I get 8% before it loses all charge, so at "92%" my comp just shuts off automatically The OG battery that it replaced lasted 5 years before it died

My laptop battery was failing, and needed to be replaced. I spent less than $100 on it used/refurbished and couldn't see spending 1/2 that or more for a replacement so decided to go with the least expensive I could find. As of now it's holding a charge and gives as good performance as the OEM that it came with when I first got it 4 years ago. It's main issue is it's not as well finished and doesn't fit well as the OEM, but for the price it's good enough. If it starts to loose the ability to hold a full charge I'll do an update, but so far I'm pleasantly surprised.

Perfect fit

excellent construction, easy to install, ecellent charge rate, excellent heat range, exact replacement

My HP Elitebook is old but still going strong, but my battery quit charging. Well, after careful review and a little bit of luck I chose to buy this battery. What sold me was it came with the tools to change out the batteries. I already have tons of little screwdrivers, but these looked nice and the battery price was within a dollar or two of all the other ones. Except for the FASCTORY REPLACEMENTS which were maybe $30 more. I've been using the new battery now for a week and it's great. I have no complantes at all. Buy this battery! It's got great tools!

This review is for TREE.NB 72.9Wh BN06XL Laptop Battery. First, it took some efforts to put the battery to its place within the laptop. Finally, succeeded. Not a problem. The battery is 6-cells. When turned on, it was at 56%, and charged to 100% within 1.5 hours (while the laptop was on). The "HP PC Hardware Diagnostic Windows" app battery test passed, only told it required a calibration. I did not do it. This is how the battery discharges with the laptop turned on with a light load (typing) or no load: It took ~7h45m to discharge from 100% to 26%. Then next morning it showed 24%, and it took 1 hour to come to 12% when Windows suggested to plug the laptop. I consider it a pretty decent result.

It does not last as long as the original but I knew it before I got it. The original battery cost $150.00 this one cost me $30.00 and does the job perfectly. Fit very well on the laptop and you have a resonable good time when the laptop is not plug in to a wall. I watched a full movie on it and still had some charge left. Very good item for the price. I recomand this item.

I got this battery for a neglected 2010 ThinkPad T410. I'd been using it on AC power during a move, and it remained on my desk next to my gaming laptop until that conked out. Since it has graduated back into regular service until I figure out how to build a new gaming rig during the RAMageddon, I decided it was time to replace the 0% battery with a new one. Always confirm your battery model before you buy, of course, but this fit my ThinkPad perfectly without any struggle or play. At full power on my old laptop on which I've been Linux distro hopping to find the performance sweet spot, it delivers about 3-3.5 hours, which I have to say is decent for the price. It's probably not the battery to get for your work truck laptop. But if you have an old ThinkPad collecting dust in the closet, rescue it with this. It'll last a few hours of browsing on the couch, streaming a movie on the third date, or playing some music at the barbecue (I know it's only April, but we're Canadians). It is definitely great value for the money if you expect what it delivers.

I don't know how they managed to make such a big battery but that only lasts for only 15 minutes. It dies so fast there's not even time for the laptop to warn about low battery, it just goes black and loses your unsaved work. Good for moving the laptop from one plugged in location to another, but not much else. Avoid. Made in China, of course.

great

Le produit semble bien fonctionner, la charge se maintient bien en mode veille, mais descends rapidement à l’utilisation.
