L14L4A01 Battery for Ideapad 500 500-15ACZ 500-15ISK, Ideapad Z41 Z51 Z41-70 Z51-70, Xiaoxin V4000 Y50C V4000-ISE Laptop, P/N: L14M4A01 L14S4A01 L14L4E01 L14S4E01 L14M4E01

I installed it on my dad's computer and it worked great. It even came fully charged which is a good thing. Although I would suggest getting some tools first before attempting to disassemble the computer, because the battery is beneath the keyboard.

Easy to install. Arrived on time. generic third party battery is exactly what I needed.

This product does what it's supposed to do, but I couldn't get the laptop to actually use it. At first it wouldn't detect it, but even after it detected it, it won't use it as a power source. Not blaming the product, but I don't know what the issue is.

YouTube provided the disassembly guide to get access to the original battery. This battery now extends the laptop to about 3 hours use. Good value.

Battery worked well for 3 months and suddenly its capacity dropped from nominal 37,440 mWh to 1,250 mWh. Even within the 3 months of it functioning I only got the maximum capacity for the first week, afterwards would never get above 30,000 mWh.

Looks acts and performs as OEM

The battery installation was easy and it worked well for about 9 months. Now, I can't unplug my laptop at all. The moment I do, it dies. I guess that's why OEM parts cost more. Lesson learned.

Battery was a direct fit, with no issues what-so-ever. Battery arrived promptly, and was well package. The price was higher than others, but the reviews and the quality of the battery was well worth the extra $$.Definitely recommend.
