As most will know, the voltage of a 12V / 20 A/h golf trolley battery is 12 and is known as the terminal voltage. The 20 Ah (Ampere Hours) refers to the capacity of the battery. This is something that you can not see but simply and as a rule of thumb, if a 12 volt, 1 Amp bulb was connected to a fully charged 12 V / 20A/h battery that are in good condition, the bulb should remain illuminated for 20 hours. 1 Amp bulb for 20 hours = 20A/h. Applying the same bulb to a 12V / 28A/h battery, the bulb should be illuminated for around 28 hours. 1Amp bulb for 28 hours = 28A/h. The only physical way of determining the actual A/h capacity of a golf trolley battery is by using a battery capacity discharge tester.
When a battery is discharged, one of the bi-products produced other than producing electricity is a sulphate contained within the battery. Sulphates disperse almost completely when a battery is re-charged ASAP after discharging. Failure to charge the battery in good time will allow the sulphates to attach themselves to the internal battery plates and build up a resistant barrier resulting in the battery failing prematurely. If a battery is dropped and even a hairline fracture is formed, oxygen will enter the battery rendering it useless very quickly.
