If your Aquaview charger is like mine it will have a plug on it. That plug will not work to charge your Vexilar battery. I would cut the plug off the charger (leaving a 6" pigtail) and solder on some small alligator clips. The clips can just be clamped on the battery terminals to charge. You can get the little clips at Radio Shack. You could still use the plug to charge your Aquaview just cut the pigtail a staggered, strip about 1 /4" of wire to clamp the alligator clips to for charging. Just make sure you don't allow the leads to touch or you will get sparks. My Aquaview charger is either a 500mah unit or a 750 mah. The charger that comes with the Vexilars is a 500 mah. It will charge fine.
