Since batteries are a significant costs of having a child with an implant...we thought we would share our discovery of a great place to buy batteries at the lowest price we have found. The link below will take you to their website. They sale various brands at great prices. We have recently been using a new battery made in China called ZeniPower that has given us the same results as the Ray-O-Vac Prolines at half the costs.
If you find a better deal somewhere...please let us know and we will put the information on our website!
