Comes with everything you need to get it installed, fits well, works great in my ROG Zephyrus G15. My old battery died and my PC was really struggling on just plugged in power alone, this by itself brought new life to my old laptop!

For my computer perfectly. And CHARGED. Still new so we’ll see how long the battery lasts

Reliable Replacement Battery with Decent Life I picked this up as a replacement battery for an older HP EliteBook, and it’s been performing well overall. The fit was spot-on—no wiggling or forcing required. The laptop recognized it right away and charged up without issue. On a full charge, I’ve been getting a respectable 3–4 hours depending on workload, which is about what I’d expect from a fresh aftermarket battery in a machine of this age. Build quality feels solid, and the casing doesn’t creak or flex when installing or removing it. The charge holds steady without sudden drops, and standby drain overnight is minimal. One thing I did notice is that it tends to run a little warm if the laptop is pushed hard for a long time, but not to the point of concern. Longevity is still a question mark since I’ve only had it a short while—these third-party batteries can sometimes fade faster than OEM. Bottom line: A good, reasonably priced replacement option if you need to breathe new life into an older HP laptop, just keep in mind that long-term durability may vary.

Item as described. The battery size is accurate, 1 full cycle to calibrate and comes with tools for fasteners and prying the case with delicacy. I would recommend this brand. At the time of this review, it has been 2 weeks since I installed it on my 5-yr old laptop.

Works well for Lenovo Yoga 410-13ikb replacement battery. Comes with all required screwdrivers.

Great product

Absolute garbage. Only held a charge for about a month and after that it won't charge past 13%. I tried all the troubleshooting steps but none of them worked, and the support website links to a dead webpage. Don't waste your money.
