Review (1/5): Beware - Delivered Product does not match description
The technial details for the battery that this seller lists for sale states "3.5v Lithium Rechargeable Has Twice the Power and Half the Weight of Ni-Cad". THIS IS NOT TRUE!!
What I received is a WelchAllyn 72200 NICKEL-CADMIUM Battery. The good news is that it is not a knock off, but the bad news is that it is not a Lithium battery and I could have bought a knock off for half the price.
I got sucked into buying this as I would love to have a lighter battery in my otoscope and was excited to see a light lithium battery. It is unfortunate that it was toooo good to be true!!
I have purchased knock off's in the past and they tend to last a couple of years. That is about the same life I have gotten from the Genuine Welch Allyn batteries. I would not have spent the money for this battery had I known it was not Lithium.
