Default Battery Date stamp

So I looked at a Cart today and it had trojons in it with a stamp of A0.

Are these 2010 batteries?
The cart BTW is a 07

Probably 2010, not 2000 or 1990. They should be almost spotless at that age.

Just wondering since I have no history on this cart per say, should I do any battery break in procedures? Also what is the average expected run time on a PDS with newer Trojons? Should I run it as long as possible till it starts to run down?

From our friends Shadowman and Scottyb:

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.
