Getting Batteries for Old But Reliable Dive Computers

from the November, 2015 issue of Undercurrent   Subscribe Now

In the last decade, it has been extremely difficult, if not impossible, to get battery replacements for many old but reliable dive computers, forcing users to buy new ones. But no more -- you can now get the batteries replaced in many old brands and models.

Bret Gilliam, once the CEO of Uwatec until it was sold to Johnson Worldwide Associates in 1997, said that when Uwatec designed the Aladin Pro in 1995, they estimated the battery lifespan would last the average diver from three to five years, based on 200 dives annually, though in reality the batteries lasted seven to 10 years. They designed it so dive stores could replace the batteries for $25, but JWA eventually stopped supporting the product.

"JWA initially charged excessive rates, more than $100 to change the batteries and even stopped its dealers from providing the service," Gilliam says. "Finally, the only option for a diver was to 'upgrade' to a new model of computer and pay a small fortune for the privilege. But many divers were happy with the original Aladdin Pros and didn't want to switch."

Gilliam, who remains "a passionate user" of the Aladdin Pro Nitrox (he owns 10), searched for alternate support and found Terry Brady, owner of Brass Anchor Scuba Center in Frederick, MD. "He provided superb quick service, changed out the batteries for $50 each, and had them back to me within five days. This is a guy who understands customer service."

Brady replaces batteries in many models of outof- date computers, too. You may reach him by calling 301-663-9363 or e-mailing To see what computers he repairs, check his website at
