B590 E530 E540 Laptop Battery Replacement for 0A36311 Lenovo ThinkPad E430 E431 E435 E440 E445 E531 E535 E545; P/N: 45N1048 45N1049 45N1043 45N1042

Perfect fit and works perfect! Great price too. Would definitely recommend.

Good replacement, served its purpose. Eventually wore out, but it's expected.

This one works perfectly so far. I was able to use for several days letting the battery percent drom to 42% before recharging. I had returned another brand twice because they went from 50 something percent to zero in minutes. Fortunately this VUOHOEG laptop battery replacement does not have that problem and is working great so far.

I bought this battery for an old laptop. It came promptly and obviously had had life in a previous environment - not a clean one. My laptop objected to this "not Lenovo" battery, but after a few uses the battery was accepted and all is well. The outer case of the battery is faded and old looking, but the battery functions well. Takes a full charge and lasts as long as the original battery when fully charged. I consider this battery to be a good deal.

Good fit for E431 but be aware of the incorrect product description. I received an 11.1v battery instead of a 10.8 v.

Replacement battery for my laptop… works great!

The battery worked normally and held its charge for weeks. But it failed completely eight months after I bought it. The computer shows zero charge, and the battery won't accept a charge at all. After 8 hours, still zero charge.When I replaced it with a battery from a different manufacturer, the new battery charged normally. Something internal to the battery has failed. A fuse?

Still working great
