I’m getting about 3.5 to 4 hours of use per charge, which is a step down from the original but still quite adequate for daily tasks. The battery does get a bit warm under heavy use, and I’ve noticed a slight discharge even when the laptop is off. Overall, it's a solid replacement at a much lower price."

"I found this battery to be a perfect replacement for my 2015 MacBook Pro. While it doesn't last all day due to the older Intel CPU, I still get about 6 hours on light use and 4 hours when streaming. Installation was simple, and I appreciate the 1 year warranty, which set it apart from other options. The included instructions could be better, but if you're comfortable with MacBook repairs, it's not a problem."

Their customer support really stands out, even though my first battery did fail sooner than I'd hoped."

"My experience with the NinjaBatt replacement was unfortunately very disappointing. The battery arrived completely discharged and never charged beyond 39%, with capacity dropping even lower on subsequent attempts. Performance was much worse than my old OEM battery, and the return process was a hassle due to the battery being glued in place. I would strongly recommend considering another brand based on my experience."

This battery brought my laptop back to life and saved me from buying a new one. Absolutely recommend it to fellow Latitude owners."

I decided to try this replacement, and after a full charge cycle, my laptop’s battery life was renewed—lasting about seven hours, even with demanding use like AutoCAD and Excel. It’s been working perfectly for weeks, and the quick charging with my original Dell charger is a huge plus."

"I found these batteries to be a cost-effective alternative for my pets' collars. They perform just as well as the original brand but at a much lower price, making it easy to keep my pets' electronic door working smoothly."

"With two dogs at home, I appreciate that these batteries are affordable and last at least two months—just like the more expensive ones from the manufacturer. They fit perfectly and keep the collar working for our electronic entry system."
