Everyone is using the battery nowadays, whether in your vehicle or for inverter, so along with using the battery, it is also important to maintain it because you have to spend a lot of money in getting another battery.   In this post, you will learn some such tips on the maintenance of the battery, by following which the battery will not get spoiled quickly and its life will also be almost doubled.  Some important tips for battery maintenance are given below.   1 (Water) The most important thing for the battery is that the amount of water in the acid present inside the battery should not be less.  Because when the battery is repeatedly charged and discharged, the amount of water in the acid present inside the battery gradually decreases by burning, so it becomes necessary to check the water level inside the battery from time to time.   And if the amount of water inside the battery has decreased, then wate...

The presented circuit diagram is designed to act as a 5 volt battery charger.  You can also use this circuit for 5v regular power supply.   Any device running on 5v DC can be connected to this circuit such as for charging mobile phone battery, LED DOB which glows from 4v etc.  In this circuit ic 7805 is used which is a voltage regulator ic.   Give any voltage 12 to 35 at the input of ic 7805 but always get 5V on its output pin.  This circuit is made up of very few components and is very easy to use.   And at the same time, this power supply is also very safe. a list of electronics components use in this circuit given below.

Presented circuit is designed for automatic battery charger.  This circuit automatically turns off the battery supply as soon as the battery reaches its full charge level.   Only one transistor BC547 drives this circuit.  The base of the transistor BC547 is connected to the positive pole of the battery by a 4.7k ohm resistance.  And a variable resistance 10k ohm is used to adjust the voltage level at the base of the transistor.   Let's assume that the battery to be charged is of 12 volts. When fully charged, the voltage level of the battery rises to about 14 volts.  And with this, the voltage at the base of the transistor BC547 increases, due to which the transistor comes into switch on mode.  And with this the relay connected to the collector of the transistor comes to the on position and turns off the supply of the battery.   The list of electrical components used in this circuit is given below. ...

The presented circuit diagram acts as 12v battery charger.   We get 10 Amp current from the output of this charger which is suitable for charging 150Ah battery.  A 0-12 10 Amp stepdown transformer has been used in this, in its output we get 12v 10Amp.  To convert 12v AC to DC, 4 diodes 5408 have been used in this circuit which are connected in parallel.   This charger is very suitable and simple and low cost charger to charge the battery.  This charger can be easily made at home.
