I had chosen a battery with the wrong connector end. I was able to easily return the battery and support was able to assure that the replacement battery had the correct end. Received in a timely manner.
Dec 2021, I got a 9.6Vdc battery for my Visonic powermax plus unit 1800mah Ni-Mh And a 7.2Vdc 2200mAh battery for my power max pro. Both battery's worked well at this time. Web site was easy to lookup batteryhawk replacement battery's from my old part numbers.
I was impressed with the short time to process and ship the order.
