Default New batteries

I just installed new batteries on a 07 club car, The guy I bought them from said to keep them charging when I wasn't riding. I have had other friends that have owned carts for years and they say to run them down almost all the way before charging.What should I do.

First don't listen to your friends--unless they are buying your batteries

Never run your batteries below 50 % of the packs volts-running the batteries below 50% will shorten the life of the batteries by a few years--

and yes keep them charged, if your not using the cart all the time and it is sitting for weeks, put the charger on them once a week to top them off--if not in use

NEW BATTERY BREAK-IN PROCEDURE:
Following proper break-in procedure can increase the strength and the useful life span of your new batteries. New batteries are initially about 75% of their full strength. The following procedure will insure they reach their full potential.
The 1st 10 to 20 complete charge/discharge cycles are critical to insure they reach 100%. New batteries should be charged before use and thereafter as follows:
Plug the charger in and leave it alone until charger shuts off by itself. Then drive to discharge the batteries to 75% battery pack capacity (see chart) Plug the cart back in and repeat the charge cycle.......It is very important you let it charge until it is completely done. Repeat this for the first 10 - 20 cycles......by the 12th cycle you will notice a difference in power, speed, and run-time.........I have never had a customer say they have not noticed the increase.
Most importantly, NEVER run the battery pack down below 50% of capacity throughout their entire life. Never leave the batteries in a state of discharge for extended periods of time. Recharge the pack once a week if the cart is sitting idle or in storage. And when in doubt, recharge it.
During the break-in procedure, keep an eye on the water levels. T can take 12 hours or more for the 1st few Charging times. These extended charge cycles may evaporate some of the water. ( use distilled water only )
As the batteries break in you will notice the charge time gets shorter. Eventually going from 12 to 5-6 hours per recharge.
ONCE A MONTH:
Routine maintenance is the 2nd most important thing to insure you get the most use out of your new battery pack. It is critical that you get into a routine of spending 10 - 15 minutes a month to keep the cable connections clean and check the water levels. Proper water level is critical. Dry batteries die quickly.
Keep the Distilled Water level up to the bottom of the fill hole sleeve or a half inch above the lead plates. Do not fill to the top.
Use a hard nylon brush to remove any visible corrosion. Carefully check that all of the cable connections are tight. Loose connections cause arching which will melt the soft lead terminals. Spray-on Battery Terminal Protector is available from the auto parts store and greatly reduces corrosive build up.
I hope this helps you get the most use possible out of your battery investment.

I agree, it is time for you to educate your friends about wet cell lead batteries. 1st of all they do not have a memory so there is no need to run them down, 2nd they sulfate badly when left below 50% capacity for long...... Best advice we can give is get a voltmeter and use it often until you begin to learn where that 50% mark is going to be ...
