To reduce battery replacement costs for two-way radios, GTE Government Services did a study on US Naval Ships by applying three battery service models: Charge-and-use, Exercise and Recondition. Recondition is a deep discharge exclusive to Cadex battery analyzers to restore nickel-cadmium batteries affected by memory. GTE discovered that Recondition provides a nine-fold cost reduction over other methods. Based on these results, GTE endorses the Cadex battery analyzers for all operations.

Maintenance Models	Annual % of Batteries Requiring Replacement	Annual Cost
Charge-and-use	45%	$45,000
Exercise	14%	$13,500
Recondition	5%	$4,500
