Before diving into the step-by-step instructions, it’s essential to understand what this charger does. The Selmar Turbo-4 is a fully automatic, microprocessor-controlled battery charger and maintainer. It typically includes:
A: While many owners have left Selmar chargers connected for extended periods (one owner reported 2 months of continuous connection), it is not recommended for indefinite use unless your specific model is designed for maintenance charging. Continuous charging without a proper float mode can overcharge and damage the battery by boiling off electrolyte. For long-term battery maintenance, consider a modern smart charger with automatic float mode.
Do not use Boost mode on small batteries (motorcycle, lawnmower) unless specified. Check your battery’s max amperage. If you encounter any issues with your Selmar
A: Yes, a 4A charger is a relatively slow "overnight" charger. However, because it is not automatic, you should monitor the ammeter.

However, it's worth noting that battery technology has evolved. While your Selmar charger can absolutely charge a standard lead-acid battery, newer "smart chargers" offer multi-stage charging, automatic shutoff, and battery conditioning features that help extend battery life. Many classic car enthusiasts keep their Selmar for its ability to revive deeply discharged batteries and use a modern smart charger for routine maintenance.
The Selmar Turbo 4 is explicitly designed for 12V lead-acid batteries . Do not use this charger on NiCad, Lithium-ion (LiFePO4), or small household rechargeable batteries, as doing so can trigger a chemical fire or an explosion.
