3 Simple Battery Desulfator Circuits Explored
In this article we investigate 3 simple yet powerful battery desulfator circuits, which can be used to effectively remove and prevent desulfation in lead acid batteries. The first method uses PWM pulses from a 555 PWM circuit using existing battery power itself, the second concept involves high voltage spikes, while the third design discusses desulfation […]
How to Recharge Dead Batteries
In this post I have explained how to recharge and use bad, defective discarded batteries using an innovative battery charging process invented by John Bedini. Lead acid batteries can sometimes be a problem to get rid of. They can also be high priced to upgrade. In case discarded in the wrong way, they have a […]
Simplest BJT CC, CV Battery Charger Circuit with Trickle Charging (Adjustable)
Today I will explain to you how this simplest constant voltage and constant current battery charger circuit works. This circuit is very nice for charging battery safely without damaging it. It has two main jobs, one is limiting high current and second is stopping over voltage. Audio/Video Representation Main Parts Used In Circuit In this […]
Low Battery Indicator Circuit Using Two Transistors Only
In the following post I have explained a simple low battery indicator circuit by using just two inexpensive NPN transistors. The main feature of this circuit is its very low stand by current consumption. The Circuit Concept We have so far seen how to make a low battery indicator circuits using a 741 IC and […]
Camper, Motorhome Battery Charger Circuit
In this post I have explained a battery charger circuit specifically designed for camper and motorhome applications, so it can serve as an effective camper/motorhome battery charger circuit operating through any shore power supply source. The idea was suggested by “music girl”. Battery Charger for Motorhomes Based on this customized battery charger circuit I would […]
