golf cart guru • Golf Cart Battery Life Expectancy Believe it or not, golf cart batteries will actually gain more charge capacity…for a while at least. Over time these same batteries will begin to have diminishing charge capacity until they need to be replaced. How long this process takes is greatly affected by how the battery and golf cart is maintained and stored. the battery system is charged will ultimately determine how long the battery will last. Generally, the less charge being used before recharging, the longer the battery will last. The chart below gives a theoretical representation of how many charge cycles can be expected based on how low the battery is run down. the Reaching 100% Capacity Obviously new golf carts come with new batteries, but these batteries only hold about an 80% charge. To reach 100% capacity requires proper charging and discharging of the batteries. This can be done by either keeping the golf cart on an automatic charger or by using your cart regularly. As seen in the chart below, this process can take between 75-100 charge cycles. Battery Life Span Charge Cycles The life of a battery is determined by how many charge cycles it can produce. How and when Battery Life Cycles Life Expectancy In theory, the life expectancy of a golf cart battery should be somewhere around 750-900 charge cycles. In reality that number is much less due to many factors including storage, temperatures, and charging practices. As roughly indicated with the first chart, a battery would be considered bad when it holds less than 60% charge. This could occur somewhere between 300-320 charge cycles. As the theoretical chart implies, the more the battery is run down and recharged, the faster it will wear out. Keeping a battery on a self charger will have very minimal affect on its life, that is why it is always important to keep your golf cart on a charger. • Have a question?
