Anton Bauer Pro Pac 14 battery showing temperature hold error on charger
20 years old. Gear and prices may have changed since.
What the thread found
- The charger and battery each contain a temperature sensor that prevents charging when the battery is too hot or too cold.
- A mushroom-shaped pin on the charger and a corresponding depressed pin on the battery enable temperature communication; cleaning these pins with a pencil eraser can resolve hold errors caused by dirt or corrosion.
- If the pins are clean and the hold error persists, the battery likely has a faulty thermal sensor causing miscommunication with the charger.
- An out-of-warranty battery in hold status cannot charge with the original manufacturer's charger but may be recelled or have the thermal sensor replaced.
- Alternative chargers like PAG analyzers ignore thermal sensor communication and instead rely on direct battery protection through thermal sensors and fuses.
- A battery in hold status should be immediately removed from the smart charger, as continued charging despite miscommunication can cause dangerous internal damage, melting, and venting.
- Removing the communication wiring between an out-of-warranty battery and its original charger allows the battery to be recelled for use with alternative chargers.
Depends on
- Solutions assume nickel metal hydride battery chemistry.
- PAG analyzer compatibility mentioned but not detailed.
- The specific cause of communication failure between individual units cannot be determined without testing.
