Reliable, Powerful, and Just What I Needed
By mzphine on Reviewed in the United States on August 4, 2025
I don’t write reviews often, but this laptop battery deserves some recognition. From the moment I installed it, my laptop instantly felt like it had a second wind. The installation was seamless—no tech background needed. It charged quickly, held the power beautifully, and I could immediately feel the difference in performance. As someone who relies on her laptop daily for both creative flow and client work, having dependable battery life is non-negotiable. This gave me peace of mind and hours of uninterrupted productivity. It also came well-packaged with clear instructions and even felt more solid than the original battery. I’m genuinely impressed by the quality. If you're on the fence, consider this your sign—NinjaBatt delivered. Highly recommend.

NinjaBatt HT03XL
By Cucucachoo on Reviewed in the United States on August 16, 2025
The first time I had to replace the battery in my HP laptop was in 2022. That HP battery lasted less than 2 years. I purchased a Emanjor HT03XL through Amazon and was able to get at least 6 hours of face time before having to recharge it. The battery began showing signs of swelling 3 years later. So this time around, I decided to try the NinjaBatt HT03XL. I followed their instructions after installation of draining the battery down to almost 10% before charging to 100% and repeat this procedure 5 times. After the 5th time I turned the laptop on with the battery at 100% and left in on with NO programs running in the background to check battery drain. Two hours and 15 minutes later the battery had already drained down to 20%. Not good. Especially if your someone who is mobile and uses their laptop a lot and needs the extra time before having to recharge the battery. Granted, power consumption is not the same on all laptops. But to get almost 4 hours less time out of this battery than what I had been getting in the past is quite disappointing.
