For example: a 36v battery pack will read 38.2v fully charged.

Generally, I like to see the maximum drop in voltage stay within one battery of the full charge. You will notice the pack voltage dropping under hard acceleration.

Attach a digital voltage meter to the battery pack and lay it on the seat for observation or simply install one of our inexpensive digital battery meters for real-time battery information. Do this on an incline to maximize test results. The golf cart can draw as much as 300 A from the battery pack on a hard start. Use the golf cart to load test the batteries.
If this condition persists, the cell is failing and the battery should be replaced. See SOC readings chart on the battery meter page. 025 spread in readings between fully charged cells indicates that the battery may need an equalization charge. The recommended fully charged specific gravity of marine batteries is 1.255 to 1.265 taken at 80☏. Specific gravity is a unit of measurement for determining the sulfuric acid content of the electrolyte. I do not recommend the ball float type hydrometer. The state-of-charge and reliability of a lead acid battery can best be determined by the specific gravity of the electrolyte measured directly with a common bulb-type hydrometer with a glass float. See voltmeter readings chart on the battery meter page. A proper load test will give the best indication of a batteries ability to perform. Testing for specific gravity will give a good indication of the batteries health or condition. A handheld voltmeter will give a general idea of the batteries health in terms of a voltage charge. There are several ways to test the batteries. The release of hydrogen gas bubbles stirs up the sediment in the bottom of the batteries and helps to maintain a healthy environment. The sound you hear is the release of hydrogen gas bubbles during the bulk recharge phase. Excessively high water levels will cause acidic water to appear on the tops of the batteries potentially running down the sides to damage the battery trays. The correct water level is 1/4 inch above the lead plates which are visible in the water fill hole. Remember that hot weather and frequent recharging can increase water usage. To be safe check the water levels every 30 days until you can establish a pattern of water usage.
It is best to pay a little more and get the larger capacity battery. While these lower-cost batteries may have an initial appeal they may fall short when it comes to sustaining the amperage delivery needed for the performance desired. The amp-hour is a unit of battery energy capacity, equal to the amount of continuous current multiplied by the discharge time, that a battery can supply before exhausting its internal store of chemical energy.īatteries with the lower amp hour capacity have a lower cost of manufacture. What is Amp Hour capacity & how does it effect performance?
Depending upon the amount of damage done the battery may take a charge but, the damage done is not reversible. Old batteries will adversely affect the cart performance as both their capacity and delivery functions diminishīatteries that have been left in a low state of charge for any period of time will suffer irreversible damage resulting in reduced capacity and delivery. Other makers will put stickers on the batteries indicating the year they were produced.īatteries lose their capacity as they age. Trojan batteries have a single digit stamped into the negative battery post which indicates the year of manufacture. Generally speaking a battery pack will last five years. Compare your readings to the chart provided here BATTERY METER CHART Use a handheld digital meter or install a handy in dash meter found on this website. How do I know what the battery pack state of charge (SOC) is? Recharge the pack anytime the state of charge (SOC) is between 90% - 50% capacity or whenever the cart has sat unused for 30 days
