Easy to install and now my laptop is finally working again.

Pleasantly surprised with the cost and the effectiveness. This is a long-lasting battery, that arrived quickly and allowed me to resume full function of a laptop that previously needed to be plugged in.

Easy install, no issues. Battery life isn’t great (1-2 hours) but is a lot better than the original 6 year old manufacturer battery.

I purchased this battery as a replacement for my HP laptop, hoping to improve performance—but unfortunately, it’s been a major letdown. From the moment I installed it, my laptop began beeping with battery warnings every time I powered it on. The battery fails to hold a reliable charge, and my laptop shuts off abruptly when the battery level is still between 40% and 50%. It’s actually performing worse than the original battery I was trying to replace. This has been a frustrating experience and, sadly, a poor investment.

It was OK at first, but weakened and then finally died only 12 days after the end of the return window.Update (June 15 2025): the seller (who reached out unprompted) has promised a full refund. So I have changed to 5 stars.Update (June 16 2025): refund was processed at the bank

Worked well for exactly 13 months on a lightly used laptop before dying without warning. Not a bad price, but you get what you pay for on a $20 battery. I'll be trying my luck with a different brand next.

I needed a new notebook battery and saw the 4-5 star reviews. Decided to take a chance - and it was the right decision to do. The old battery easily came right out, and this battery replacement fit exactly like the old battery. It took maybe 10 seconds. It was already 40% charged so I started the computer to make sure it was connected correctly. No issues at all- started right up and the annoying "replace battery" screen ( from my computer) was no longer shown. I used the notebook on its new battery for 30 minutes to try out the battery, and it was still at 86% fully charged. Will definitely buy any future computer batteries from them again.
