Great Battery Life
I have been waiting for this restock. It's always nice to have a spare battery when the powerful workstation eat up a lot of juice. I thought it was gone forever because it was sold out for a long time. Thank you Lenovo for bring it back. Now my P52 can last little bit longer now.

It works
Well, really, what can you say about a battery? It works? It holds a charge? This one does. This is the battery that came with my P52 and I wanted a backup. This one works great.

A solid replacement/back-up battery for the P52!
Pros: Works exactly the same as the battery that came with my P52. Battery life is consistent, predictable, and on par with the original battery.
Cons: Pricey.

Keep the monitor brightness down
Only okay life. I get about 4 hr avg. Not bad but you need to keep the monitor brightness down to keep the battery life manageable. Since there is no internal battery for the laptop I can't switch it out mid work session. The avg 8-12 hr life of other laptops now, for the size and weight of the laptop it almost isn't worth it. The P52 is very powerful so it needs a lot more battery to take that kind of processor/cpu load. At least I can switch this battery out and have a few on hand so my laptop will last longer where other laptops have a shorter lifespan and you can't switch out batteries. This battery is just barely worth it. To get 5 stars it needs about 10-20% more life. IE, it would not do well on a flight. This is a desktop style laptop/battery. NY-LA it will die somewhere Nebraska.
