How long does it take to charge a 12V battery at 5 amps?

A charger with 15 amps, for instance, will take about two hours to fully charge a battery at a 25-percent discharge value. Chargers with only 5 amps, however, will need a full six hours with the same battery.

Can I use a charger as a power supply?

— the charger is going to be holding a voltage, and the charging circuit will be hidden close to the battery, inside the device itself. These chargers often can be used as power supplies (remember to not exceed the rating printed on the charger!).

Will a trickle charger charge a dead battery?

You can’t “resurect” a dead battery with a trickle charger. A trickle charger is meant to maintain a fully charged battery. Bring the battery inside for 24 hours then put it back in, drive around for an hour and have the electrolytes checked at your trusted local repair shop.

How long does it take to charge a 12 volt battery with a 6 amp charger?

How long does it take to charge a car battery? A small car battery can be charged in 4 to 5 hours, a mid-sized battery can be charged in 5 to 6 hours, and a large car battery can be charged in 7 to 10 hours.

Can I charge a 12V battery with this charge?

With this charge you can charge any type of 12 v battery even your car battery it is very necessary in cold days because battery drains out very quickly . This Charger features 2 step Charging 1. Constant Current 2. Constant Voltage it’s will convert 19 volts from your charger to 14 volts to charge the battery

Can I plug a 12V to a 5V adapter?

You can if you want to damage the 5V device. No do not be plugging adapters in any device with different voltages than specified by the manufacture for that device. You can get 12V to 5V, I assume USB, adapters and then you can use the 12V adapter to drive the 5V adapter and then plug it into the 5V device.

Can You charge a 12V battery in series with a resistor?

You can, provided that the battery is charged according to the battery specification. Depends on what type of battery it is, if its a nicad/nimhi or sla type you can put 12v in series with a resistor, or direct onto the battery, if is a li-on lifepo you need a charger chip. As DD just said, it’s all about the battery.

What voltage should a 200Ah battery be charged to?

A 200Ah battery must be cut-off when charging current gets to 6A. Charging over and above this may harm the battery. NOTE: By measuring just the voltage is not going to inform us if the battery is completely charged or not. It’s the current which reveals the actual condition of charge.
