How Purkeys Remote Sense Alternator Can Prolong Battery Life

The charging circuit between the battery and the alternator can lose voltage when wiring ages, corrodes, becomes loose, or is not properly connected. A traditional alternator will maintain 14 volts at the alternator’s output terminal but the voltage at the battery pack is less, due to voltage drop in the circuit.  As a result, the battery pack will likely never reach a full state of charge. This reduced state of charge damages the batteries and leads to a significantly shorter life span.

Purkeys recommends fleets use a remote sense alternator. The alternator’s output adjusts based on the voltage at the batteries. The remote sense lead is a second wire between the battery and the alternator’s remote sense terminal. It ensures the batteries quickly return to a full state of charge and remain near full capacity. By ensuring a battery is getting the full 14 volts it can:

• Improve battery charge time, especially in cold weather
• Improve the life cycle of the battery
• Decrease warranty claims

When fleets begin having electrical problems, the battery is usually the first to be replaced. A remote sense alternator can be a simple solution to save fleets time and money in the long run. Instead of constantly replacing parts, a remote sense alternator will lengthen the life of a fleet’s batteries. Keeping trucks out of the shop and drivers on the road will increase revenue and productivity.
