In this guide, we break down the official instructions into digestible steps, covering safety, setup, charging modes, and troubleshooting.
If your battery is not a "maintenance-free" or "sealed" type, carefully check the electrolyte levels. Top up with distilled water if necessary.
Check the physical condition of the battery. Do not attempt to charge a frozen, cracked, leaking, or visibly bulging battery. If it is a maintainable battery (with removable caps), check the fluid levels and top them up with distilled water if necessary before starting. Step 2: Clean the Battery Terminals

Standard Lead-Acid, Sealed, and Maintenance-Free batteries (16Ah to 80Ah capacity)
The Selmar Turbo 4 is a robust, 12V 4A manual battery charger designed for efficient charging of lead-acid automotive and leisure batteries. As a manual charger, it requires active monitoring to prevent overcharging, as it does not automatically shut off when the battery reaches full capacity. Voltage: 12V DC. Charge Rate: 4 Amps RMS (approx. 2.7A - 2.8A DC).
Store the unit in a dry, cool environment away from moisture and direct sunlight. To help tailor this information, please let me know: In this guide, we break down the official
