Batteries and charging

The charging system and battery pack on an electric golf buggy account for more faults than any other system, and most of them follow a small number of patterns. The guides in this category cover chargers that stay silent or click without ever charging, packs that lose range, corroded terminals, battery testing and watering routines, lithium packs that will not wake after storage, and packs that go flat overnight. Before assuming a charger has failed, check the pack itself. Many automatic chargers refuse to start a cycle if the pack voltage has fallen below their wake threshold, so a deeply discharged pack can make a healthy charger look dead. A rested 48 volt lead-acid pack typically reads close to 50.9 volts when full; below roughly 48.5 volts it is significantly discharged. Reading each battery individually with a multimeter will often expose a single failed unit dragging the whole pack down, because one weak battery lowers every figure the pack produces. Confirm the supply socket is live and the charger fuse intact before condemning the charger, and look for green or white crust on the terminals, which adds resistance and heat. Voltage testing, watering and terminal cleaning are safe owner jobs if the pack is treated with respect. A swollen or bulging battery, cables that run hot or melt at the posts, or any smell of burning are engineer work; book a Hawke engineer rather than continue investigating.
