4A Smart Charger
Keep your vehicle battery topped up and healthy with the Halfords Advanced 4A Smart Charger. It uses a multi-stage cycle to charge and protect your battery.
This smart battery charger will automatically switch to a maintenance mode when your battery is fully charged, which protects it from overcharging and keeps it healthy long-term. If you're charging over the winter, the cold-weather maintenance mode protects your battery in low temperatures.
It can be used for both 6V and 12V vehicles and is compatible with start/stop technology. The large LCD clearly shows the voltage and charge status, and since it's backlit, you can recharge in low light or at night.
