If you're thinking of buying a second hand trolley then apart from the trolley it's a good idea to first have the battery and charger professionally tested.
These items are quite expensive to replace so it's better to be safe than sorry.

Don't forget, now is the time to think about havng your electric golf trolley or buggy checked and serviced in readiness for the start of the season.

I've had a couple of trolleys in recently with completely seized clutches.

The trolleys have both been stored away in a wet condition (without drying them off) within a canvass "trolley carry bag".

If you keep/carry your trolley in one of these useful bags, it's best to first ensure your trolley is as dry as possible.
