Cart Batteries
Trojans usually last 5 to 7 years depending on their maintenance program..
The cart charger, unless it is antique, is self regulating & will only charge what it needs to.,. so you can plug it in daily or weekly..
you could buy a charge meter, $25 or so which will let you keep a better eye on it... I usually charge the shop cart once a week unless someone really uses it up then when it slows down or the charge light is flashing, we plug it in...
When you replace your batt's, change the cables to 4 Ga... makes a difference.
Also on any cart always keep the connections TIGHT & CLEAN.. use a waterproof grease or we use a battery terminal cleaner & corrosion inhibitor...
You can get these at the auto parts store... PLUS, check the water & keep topped up with distilled water...
