Futurebatt 6Cell AA-PB9NC6B AA-PB9MC6B AA-PB9NC6W AA-PB9NS6B Laptop Battery fit Samsung R420 R430 R468 R470 R480 RV510 RV511 RC512 R519 R520 R530 R540 R580 R730 Q320 Q430 Np550P5c Np365e5c

Easy installation, battery had 71% charge and is working perfectly fine!

Difficult to find a battery for my older Acer Aspire V3 laptop, but this battery was a good replacement. I was surprised that as delivered, it was charged to 75% with an estimated run time of 42 minutes! It fit my laptop without any difficulty. The price was also quite good, and it was promptly delivered. My previous battery was bought from Amazon in March 2023 but stopped holding a charge about 2 years later. It was a "no-name brand", and it is not listed on Amazon's website anymore. FutureBatt seems to have a better reputation. Time will tell. I think when this battery dies, it will most likely be time to replace the laptop.

Fit my old HP 620. Under $19.00, so had to try. My old HP 620 did recognize the battery, no issues noted. This laptop was updated with windows 10 and a Solid State Drive. All else is original. Battery lasts for 2+ hours right now. One Note for buyers: Instructions/install/safety manual states install battery & drain first time to 3% & then charge up to 100% uninterrupted. I installed the battery, with the Laptop power supply disconnected. Laptop powered up properly & showed 73% on battery icon. Watched it discharging in a reasonable time frame from 70 to 60 to 55 to 53%, & then the power dropped out & dead stop. Would not restart on the battery alone, so plugged in & fully charged. The battery now runs the full range as reported by windows 10. My point here, to the supplier & buyer, is that the first install of the battery appears to give a false reading, so you have no way to control it getting down to 3%. Luckily the Laptop reported it had a safety shutdown at 6% (when it restarted), and then asked me to restart normally. YES. Seems like windows 10 now recognizes this battery's full range once it was fully charged & discharged a 2nd time. So far I'd recommend to buy, but time will tell the overall life of the battery.

Upgraded and works great. Been through several cycles and no issues. Delivery was delayed 4 times so can't give it the full 5 since I lost work because of it

The battery is bad! I don't use my laptop that it works for very often, although this new battery worked at first, with it charging up fully to 100%. I don't keep the computer plugged in except when using it, however, and in order to help calibrate this new battery, I next used my computer running off of this battery for a couple of hours without it plugged in. After these couple initial times with this new battery, however, the next time I plugged the laptop in, it wouldn't recharge AT ALL, the Windows Laptop reporting with a message finally that the battery was bad obviously because it wouldn't charge anymore, it remaining at where it had last discharged down to 45% charge. So it obviously was a BAD battery from the nearly the very start! But now my time window has passed for returning it because of having used it so little, even though it's only been 3 months of having this new battery. So these cheaper batteries are hit and miss whether or not you get one that works/lasts for very long! :(

Fit perfectly and works like a charm. Be sure of your model number. I have bought a replacement computer every 3 to 5 years and each have a different battery.

Works great.

After trying another battery replacement that lasted less than 5 months and with a performance that was not even close to the original one, I decided to bet on this one (after reading several reviews from this brand and others) and I am glad I did. So far (a little over 2 months) this battery is working as good as the OEM. I will update in a couple of months to update about performance degradation (if any). Update: After more than 6 months the battery is still running strong and is not showing any noticeable degradation. Once again, very recommended.
