received the battery, removed the old one and inserted the new one, charging it for several hours. Battery would not work, when th laptop was plugged in the battery did not allow the circuit to complete for power to the computer. I reinserted the old battery and was able to use the laptop using plug in power. I contacted customer support at Revain, they credited my account for the battery.

Quick delivery with prime. It fits my HP red flyer perfectly. It also came with half charge, which I wasn't expecting so that was an added bonus. Most replacement batteries have to be fully charged before using. An it came at a great price!
