I would like to share a very positive experience with this seller. All my questions were answered quickly and in detail, and I was provided with clear and complete instructions for installation and use. The support was attentive and truly willing to help at every step. The battery is 100% working and fully matches the described specifications. The product quality is excellent and everything works perfectly without any issues. I also want to highlight the good packaging and fast shipping — the item arrived safely and right on time. My issue with the laptop was resolved quickly thanks to the helpful guidance and fast communication. Overall, I am very satisfied with the level of service, product quality, and customer care. I highly recommend this seller as reliable and responsible.

The battery in my RV511 laptop has been dead for years. Getting it back into shape for a project and wanted a new battery because I didn't want any issues with the dead one. This battery looks good, works good. No issues.

I purchased the NinjaBatt for my 10-year old Samsung Notebook 3 laptop. I've been using it for about 2 months now and it seems to be performing very well. The included instructions were a bit confusing. A "Supplement Illustration of Laptop Battery" card says to let the battery totally discharge and then recharge completely for 2 cycles before regular use. The instruction booklet says to discharge to 10% and fully recharge for 5 cycles. I used the 10%, 5-cycle method since I usually don't allow my battery to get to 0. I'm glad this battery was available to let me get more life from the Samsung laptop which has been a real work-horse.

Perfect fit. Snapped in securely. To date, I have not encountered any issues during the charging cycle or when in use. Battery runs cool while charging and while in operation. This battery replaces the original in a 2012 Samsung laptop. This PC is power hungry and this battery performs well, giving me at minimum 3 hours of uninterrupted work time. I rated "battery life" as 4 stars, because I haven't used my dvd disc drive. I do not know what the demands of that drive will be on the battery. This battery also comes with a 12 month warranty, which is worth noting. Yes, there are less expensive replacements out there, but none offer any protection beyond 30 days at most. This item is well worth the consideration. I'm satisfied.

Very pleased with this item. Old laptop running like new!

I bought this battery based on it having safety circuitry to guard against overheating from too much current draw. It fit perfectly and I followed the instructions on breaking it in for optimal charging. So far so good. No complaints.

Perfect! As described, good price. No problems whatsoever. Was worried about compatibility because I’ve had trouble finding other compatible products needed but it’s the right one. Seller was helpful, shipped and arrived promptly. Very pleased.

This is battery worked great as one would expect on Samsung laptop. We also purchased Ninja battery for Lenovo laptop, it is still working fine ~ year later. So.... hoping both batteries hold up for the long haul. Such positive results are not always the case w/ other brands in the past. 5 stars.

I did not want to spend too much money on a 13 year old laptop. I think the price was reasonable and the battery specs met my needs. I purchased this NinjaBatt knowing that the original battery capacity was 57Wh (5200mAh), but this NinjaBatt was only 49Wh (4400mAh). Note that the battery needs to be cycled 5 times on first time use: use the battery until the battery level reaches 10% before connecting the AC adapter and fully charge the battery - do this 5 times. So far, I completed one cycle and the performance of the battery is good. The battery lasts about 3 hours before needing to be recharged. I am happy with this NinjaBatt and I recommend it.

Laptop werkt weer als nieuw.

Good product

ich hab es gar nicht für möglich gehalten für meinen so alten aber noch voll funktionierenden Laptop von Samsung noch einen Ersatz-Akku zu bekommen, Preis Leistung absolut Top und funktioniert wunderbar, passt ohne Probleme und mit der Akkulaufzeit bin ich zufrieden, bei so einem alten Gerät kann man froh sein, das es noch Anbieter gibt, die hierfür Ersatz anbieten und das zu einem sehr guten Preis.

Cette batterie fait le job pour les model cité , de mon côté je n'est pas eu la chance d'avoir la bonne batterie ! Elle n'est pas compatible ( du moins si elle et sauf qu'il Y'a un petit décalage de 3mm entre la fiche et le plastique ) donc elle ne rentre pas dans son emplacement . Pourtant j'ai déjà acheté de nombreuses batterie chez ninjabatt
