    Replaced a manufacture battery on my monitor. Now my device works like a new. Almost replace it with a $3000 unit. Product rep was quite disappointed I am sure. I am sure the unit will continue to work for some time.My Welch Allyn device is a bit older and I needed to modify the connectors to attach to this battery. However this was only a small problem.

    Excellent battery. Purchased two of them for my emergency lighting. They charge and hold their charge. I have tested both emergency lights by turning off the power to the circuits while gone for a couple of hours. Upon return the lights were still operating. Circuits were powered again and the batteries charged.

    worked out well. In fact, my other Welch Allyn device battery gave out right after I ordered the first one.Quick delivery and at a fraction of the price the Welch Allyn sells it for!
