Works very well after tweaking, April 11, 2012 By MW

After doing a simple tweak to this battery, it works very well and holds much more charge than the original provided with the vacuum. The problem on delivery was that the metal tabs in both the Shark vacuum and the Shark charger weren't making any contact with the metal strips on the new battery. As a result, the battery appeared to be dead. I then carefully bent these tabs (on the vacuum and charger) maybe 1/8 of an inch towards the middle to give the battery a tighter fit, and electrical contact was then successfully made between the battery contacts and both the charger and the vacuum. (I googled the problem and that's how I found the solution.) It appears the battery contacts don't quite match the dimensions of the vacuum and charger, but after this easy tweak, it works perfectly!
