Golf Cart Battery Comparison

--------------------------------------------------------------------------------

The following data may be helpful in comparing batteries among different manufacturers. Please keep in mind that only deep cycle batteries specifically designed for golf carts should be utilized in our carts. In fact, deep cycle "marine" type batteries will usually not work satisfactorily. And most certainly, automotive "starting" batteries should never be used in a golf cart. Using an incorrect battery will most likely result in short run times and early battery failure.

Misc. Info

Voltage on a fully charged battery in good condition will read 2.12 to 2.15 volts per cell (about 12.75 volts for a 12 volt battery, or 6.40 for a 6 volt)


Specific Gravity Readings to determine State of Charge:

12.75 & Above = 100% Charged
12.60 to 12.74 = 85 to 100% Charged
12.40 to 12.59 = 75 to 85% Charged
12.20 to 12.39 = 50 to 75% Charged
12.00 to 12.19 = 25 to 50% Charged
12.00 & Below = Fully Discharged


In both voltage and specific gravity readings, consistency among cells and among batteries is important.




Battery Load Test

Typically you don't want to see a reading lower than the starting voltage minus 1 battery from the pack.
So 38v starting point minus 1 6v battery or 32v under heavy load
50 starting minus 8v = 42v low reading under heavy load.

If lower reading is gotten repeat the test for each individual battery using a handheld meter an alligator type clips.
A 6v battery should not drop below 5v
An 8v battery should not drop below 7v
And a 12v battery shouldn't go below 11 volts

The chart below is for US batteries
That is why it is higher than the other charts
