Simple Charger for All Battery Types

Here is a Very Simple Electronic Circuit Diagram Project of  Simple Charger for All Battery Types. Note that the stability is observed when the load current and will change slightly of the supply voltage. Likewise, the fact is usually overlooked, but if you want a perfect stability – stabilize the power supply. Calculation of the current is very simple – the current in amperes is equal to 1.2 divided by the resistance R1 in Ohms.

Simple Charger for All Battery Types Circuit Diagram:

 To display the current used transistor (germanium necessarily because of the low voltage opening) that allows you to visually observe the currents to 50 mA. Diode D1 and F2 fuse protects the charger from the battery reverse. Capacitance C1 is selected from the formula: 1 amp should 2000uF.

The advantages of the proposed device: short-circuit protected it does not matter the number of elements in rechargeable battery and type – can be charged and sealed acid and lithium 12.6 3.6 and 7.2 V alkaline Switch current should be included exactly as shown on the chart – in order to remain in any manipulation of the resistor R1. The use of alternating low-impedance resistor is undesirable because of instability of sliding contact with load currents over 0.2 A.
