Features

There are several advantages of using a 12v trickle charger:

• It helps to extend the life of your battery. By providing a constant low level of charge, a trickle charger can prevent the battery from deep discharging, which can damage the battery and shorten its lifespan.
• A 12v trickle charger is very convenient. You don't need to worry about removing the battery from the vehicle or equipment every time you need to charge it. You can simply leave it connected to the trickle charger and it will be ready to go when you need it.
