Battery Life and Recommended Practices
Battery life is very difficult to predict and can vary greatly based on a number of factors including:
Battery age
Machine configuration
Engine starting frequency
Ambient conditions
Storage practicesThere are a number of components that draw small amounts of electrical current even when the key switch is OFF. Some of these include:
Electronic control modules for the machine, engine, emissions system, etc
Radios or displays with memory features
Product Link or other GPS-based systemsIt is recommended to start and operate your machine normally for at least 15 minutes every few weeks to prevent battery discharge which may damage the battery beyond simple recharge. This time should be extended during the winter as the load on the battery increase with extended heater usage, heated seat usage, and typically increased usage of the work lights.The use of a battery disconnect switch or disconnection of the battery cables is recommended if the machine will sit longer than a few weeks under normal conditions. The use of a battery disconnect switch may be advisable at the end of each working day in extreme ambient conditions.Additional references:
