Electrical Theory 101: Volts, Amps, and Ohms
We’ve covered some of this already in a previous article on battery chargers, but it warrants repeating that what we think of as electricity is actually a mishmash of three separate but related phenomena: voltage, amperage, and ohms.
Cable Resistance
Think of the act of resisting: whether it is a tantrum-throwing toddler or a stuck zipper on your jacket, the idea of resistance boils down to two opposing forces fighting with each other for dominance. In the process of trying to overcome the other, friction develops.
Battery Charger Inefficiencies
You may have noticed we said resistance is partly why battery chargers can get hot. There are other reasons as well, not the least of which is the inherent inefficiencies of the inverter that turns 120-volt household AC (alternating current) into 12-volt DC (direct current) required for automotive applications.
Battery Charging Resistance
Another point to consider: batteries become more resistant to charging as they get closer to being fully charged. To understand why, consider your drained battery as an empty chamber. To start recharging it you hook the battery up to your charger, and which at once begins to dutifully siphon power from the electrical grid via your household outlet.
Parting Thoughts
Battery chargers will inevitably get hot. It’s an unavoidable byproduct of transferring energy from one source to another; somewhere along the lines, inherent inefficiencies and resistance will cause some power to be lost in the transfer. That lost energy is the heat we feel when we touch a surprisingly hot battery charger.
What happens if your golf cart battery is low?
Weak Battery Voltage. One or more of your golf cart batteries are likely to have a low voltage. This can stop the batteries from being able to pick up charge.
