A trickle charger is a tool that gives a small quantity {of electrical} present to a battery over a protracted time period. This may be helpful for sustaining the cost of a battery that’s not getting used recurrently, reminiscent of a battery in a automotive that’s not being pushed.
There are lots of several types of trickle chargers obtainable, however one of the best DIY 12v trickle charger is one that’s easy to construct and makes use of cheap elements. One common 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.
