Q. How will I know when my golf buggy battery needs replacement?
A. Batteries will normally fail gradually.

They slowly loose the ability to store the power or amps needed to make 18 holes of golf, This is happening from the first time the battery is used and is a combination of how often it is used, how much power is taken out of the battery for each discharge and also an age factor. Therefore your battery will gradually get worse from round to round, the first you should notice is that you are walking faster than your buggy can go on the last hole, then you will notice the same thing a little earlier each round. If you need to push your buggy it is time to replace the battery.
