Batteries need more than charging

The energy a battery can store gradually decreases with usage and age. Radio users are often unaware of capacity fade and continue using the battery, compromising reliability. Batteries for public safety should be replaced when the capacity drops from the original 100% to 80%.
Very few batteries produce a capacity of 100%.

Attaching a battery label containing service date, due date and capacity reading simplifies battery management. Only batteries with valid date are used. Expired packs are serviced with a battery analyzer to condition and verify capacity. Label printer prints test results on label after each service. |
A simple, self-governing maintenance system is illustrated below. A large battery fleet only requires 15-30 minutes per day for service. Maintenance prolongs battery life and promotes user confidence.
| Taking a battery from the charger, the user checks the service date on the attached label and if expired, removes the pack for service. | ![]() |
| The Cadex battery analyzer services the battery and generates a new label showing the date, due date and capacity. Batteries falling below the target capacity are removed. | ![]() |
| The re-certified batteries re-enter service; the failed ones are replaced. This system assures that all packs meet a minimal required capacity level. | ![]() |
Cost savings with battery maintenance
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% | $40,500 |
| Exercise | 14% | $13,500 |
| Recondition | 5% | $4,500 |
