A trickle charger is a tool that gives a small quantity {of electrical} present to a battery over a protracted time frame. This may be helpful for sustaining the cost of a battery that isn’t getting used recurrently, reminiscent of a battery in a automobile that isn’t being pushed.
There are a lot of various kinds of trickle chargers out there, however the very best DIY 12v trickle charger is one that’s easy to construct and makes use of cheap elements. One standard design makes use of a transformer, a rectifier, and a resistor. The transformer steps down the voltage from the wall outlet to 12 volts, the rectifier converts the AC voltage from the transformer to DC voltage, and the resistor limits the present stream to the battery.
