Check stored batteries every 2-3 months. Top off the charge if it drops below 40%. Lithium batteries have extremely low self-discharge rates compared to lead-acid. But periodic monitoring prevents unexpected complete discharge. Complete discharge could trigger protective shutdowns.
Store batteries in temperature-controlled environments when possible. Lithium batteries tolerate temperature extremes better than lead-acid. But consistent moderate temperatures extend their calendar life regardless of usage patterns.
Operating Techniques That Maximize Longevity
Avoid running your golf cart until the battery completely depletes. Lithium batteries handle deep discharge better than lead-acid alternatives. But regularly depleting them to 10% or less still creates unnecessary stress. This shortens lifespan.
Maintain steady, moderate speeds when possible. Rapid acceleration and high-speed operation draw maximum current from the battery. This creates heat and stress. Heat and stress impact longevity over time. Smooth, consistent operation maximizes both range and battery life.
Plan your routes to minimize steep hill climbing when possible. Lithium batteries excel at high-current applications. But consistently demanding maximum power output generates heat and stress. This gradually reduces battery life.
Environmental Factors and Battery Protection
Climate Considerations
Hot climates accelerate chemical reactions within batteries. This potentially shortens lifespan even for temperature-tolerant lithium technology. Park your golf cart in shaded areas when possible. Consider installing ventilation fans in enclosed storage areas. This prevents heat buildup.
In cold climates, allow batteries to warm naturally before demanding high current output. Lithium batteries function in cold temperatures. But their internal resistance increases when cold. This makes them work harder to deliver the same power.
Physical Protection Strategies
Secure batteries properly to prevent vibration damage during operation. Excessive vibration can damage internal connections. It gradually degrades battery performance. Use appropriate mounting hardware. Check periodically for looseness.
Protect battery terminals from corrosion and contamination. Lithium batteries don’t outgas like lead-acid batteries. But keeping terminals clean ensures optimal electrical connections. This prevents voltage drops that force batteries to work harder.
