As good or better than OEM.

Very well packaged, a really snug fit in my EliteBook 8570p (a good thing). Charged relatively quickly. Battery life appears good given what I use the laptop for (network diagnostics, router programming and testing).

Pros
  • Works great
Cons
  • May not work in extreme temperatures

Pros

Cons
  • May require additional software updates

My laptop is working like a charm & it holds the charge

As advertised! Thank you! My laptop is working like a charm & it holds the charge. Just followed the instructions that came with the battery and It's been at least 1 -2 months & I have no issues. I highly recommend.

Pros
  • Ease of use and it charged ok
Cons
  • May not have enough power to support external devices

It fully charged to 100%

Easy to install. This is a new battery for one I just returned to Revain. This one arrived within a day after ordering. I installed it, and this morning it is up to 100%. This one cost $10 more than the other one I bought on Revain. I am very pleased with Revain's return policy as well as this new battery. Will re-visit this comment if things change. BTW, the one I returned, never did show a 100% charge, so I expect good results with this one.

Pros
  • Can’t really give it a full review yet only had it a few days. Took a charge and holding so far so good!
Cons
  • May not have good customer support

Won't hold a charge

Got the battery. Easy to install. Had about 70% charge according to battery meter. Charged to 100% shut down laptop put it in closet. Pulled it out the other day. Hit power button. Crickets. It wouldn't turn on. Plugged it in for two days still nothing. Took battery out of another lap top put in mine started up. Put new dead battery into that laptop I just took other battery out of and now it wouldn't start. Put multi meter on battery after plugged in two days. Dead

Pros
  • TRUE CHARGING CAPACITY THAT LASTS: Every one of our replacement notebook batteries are tested to meet OEM specifications. Our 6 cells Li-ion battery is rated at 48wH/4400mAh/10.8V - true charge capacity that won’t let you or your laptop down.
Cons
  • May not work with laptop cooling systems
