Video: 12 volt batteries in a Golf Cart
Using 12 volt batteries in a Golf Cart
I learned a very expensive lesson.

I neglected to disconnect my golf cart batteries from the Golf Cart over the winter. Nor did I turn on the tow-switch on the cart. By leaving the golf cart batteries connected and the tow switch disabled, the cart constantly draws a tiny amount of power. Over time, this draw drains the batteries down to nothing.
Batteries can withstand being left out in the freezing cold all winter, but ONLY if they are left fully charged. Trickle charging also helps, but isn’t required as long as the batteries are fully charged and disconnected at the beginning of the season.
That’s an expensive listen to learn, as six of these from battery world – Trojan branded 8 volt batteries – were going to cost over $1,400.00.
So, to save a little bit money (and I’m going to get blasted by those golf cart purists out there), instead of six 8 volt batteries (6 x 8v = 48v), I went with four 12 volt batteries in a Golf Cart (4 x 12v = 48v). This cost me just over $500 from Costco – I saved nearly $900.
Now, it is vital to remember that these are NOT regular car batteries, they MUST be deep cycle batteries. The type commonly found in marine and some motorsport applications.
Regular car batteries are meant to be kept at full charge almost all the time – they lose their ability to supply power if they’re drained too low too often – they’re designed for cranking amps, not a sustained draw.
Deep Cycle Batteries, however, are designed to be used and recharged over and over. They don’t offer as high rating for cranking amps, but that’s okay, because the 12 volt batteries in a golf cart do not require cranking amps. Rather, they draw on the power of the batteries over time, draining them down much lower than a traditional car battery would be able to handle.
So, there you have it. As long as you’re using a good quality deep cycle battery when using 12 volt batteries in a golf cart, you won’t have any issues doing so. Though, if you’re doing a lot of driving on a daily basis, the manufacturer suggested 6v or 8v batteries should be used – you’ll get better long distance performance.
