A battery charger, or recharger,[1][2] is a device that provides electricity to convert into stored chemical energy for storage in an electrochemical cell by running an electric current through it.
Laptop charger supplies 19v. The charging voltage for a 12v batteey should 13.5v-14.2v. The 12v bulb is used to act as a resistor so that charging voltage across the battery terminals is around 13.5v to 14.2v. The bulb will aslo act as charge indicator being bright when battery charge is low and dimming when fully charged. Similar setup can be used to charge electric car toys with 12v batteries.
Cool! Hindi ko na kelangan mag pa charge ng battery dun sa masungit na battery shop owner. 70 pesos isang oras na nga lagi pang andaming nakapila. Kaya anlaking tulong nito! Iwas abala na nakakatipid pa. Maraming salamat paps! Ampogi pa ng vlogger! Ahahay
Parang kulang ang TWO hours na charging time kung 2 amperes ang charging current. Bale 4 Ampere-Hours lang sya. Kung 30AH ang battery mo, dapat 15 hours ang charging time, di ba?
