Default 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.

More data may be added as it's collected.

Note: With the Forum Admin's approval, I may add another topic with price information. In the interim, if you have current pricing on any of these batteries that you feel is an exceptional deal and would benefit others, please feel free to email the who-what-where-when info to me.

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.

Default Re: Golf Cart Battery Comparison

WWIND, if your NAPA store is charging the same price for the 8146 as an 8144, then going for the 8146 should be a no brainer as it has more reserve capacity (which should equate to more run time). But it looks to me like you could be mistaken about the 8147 being equal to the Excide GC2-H, as the NAPA web catalog shows it to be less capacity and weight than the 8146.

Here's a link; please let me know if I am wrong...
