★★★★★ Our old battery lasted maybe overnight in a "sleep mode" and an hour at the most in an active state. I had replaced the last battery with a factory replacement in hopes that there would be more of a useful life. Unfortunately I was wrong and am now also realizing that I paid twice as much.I have had this replacement battery now for less than a month but am finding it is outperforming my other two batteries. The battery definitely last overnight even when my laptop does its auto updates and scans. This morning the battery indicated to still have 50% and now in the afternoon is indicating 34% remaining with continuous use.An excellent battery outperforming the prior factory replacement.
★★★★★ July 19, 2018: I put in this battery and immediately it worked. It has been a great purchase for this battery for a Toshiba, Satellite P855.Sept 13, 2018: The LAPTOP has been getting screen notices for 3 weeks now that the battery is bad and must be changed. Then the laptop shuts down in less than 30 minutes and must charge about an hour before the laptop will turn on...TSKYBEAR has agreed to replace the battery, so they may examine the reason it failed. Waiting for the label. What a GREAT COMPANY!
★☆☆☆☆ My old battery won't hold a charge, but it still shows that it's charging. I can unplug my laptop and it'll work on that old battery for about a half hour. This new one, though, doesn't work at all. It fits in the laptop like it should, but the computer says the battery isn't charging. It registers that the new battery is at 56% but when I unhook the power cable, it instantly dies. In fact, with the new battery installed and the power cable plugged in, my laptop won't even power on. I have to remove the new battery and either go battery-less or install the old battery just to get it to power on. Sending back for a refund.
