6 FAQs about [There is no current when the charger is connected to the battery]

Why does my battery charger not output a voltage or current?

The charger does not output any voltage or current. Check the power source and ensure it is providing power to the charger. Verify that the charger is properly plugged in and the power switch is turned on. The charger outputs the wrong voltage or current. Adjust the charger settings to match the requirements of your battery.

Why is my battery not charging?

The problem could be a faulty power cord or a blown fuse in the charger. Check the power cord for any damage and try plugging it into a different power outlet. If that doesn’t work, you may need to replace the fuse. When I connect my battery to the charger, nothing happens. What should I do?

What happens if a laptop battery is 100% charged?

As soon as the battery displayed “100% charge”, you yanked out the power cord from the laptop, but forgot to switch off the mains or remove the charger from the wall. What happens then? In such a situation, the charger will still draw a minimal current from the mains and the regulator will maintain a steady supply of 5 V.

What happens if a charger is not connected to the main power source?

However, if the charger remains connected to the main power source and is not connected to any ‘load’ for days on end, the electricity wastage extrapolated over weeks and months and years may be considerable. At the end of the day, however small in magnitude, it’s just wasted power – power that you could use to charge your devices many times over.

Why is my battery not responding when I connect a charger?

But if the worst comes to pass and your battery discharges completely, it won’t respond when you connect a charger, at least not initially. The amp meter stay at 0 amps (or near it). However, after fifteen minutes, the amp meter will gradually rise, showing that your battery has started accepting the charge. 2). Loose Connection

What happens if a laptop charger is not connected?

In such a situation, the charger will still draw a minimal current from the mains and the regulator will maintain a steady supply of 5 V. Since the charger is not connected to the laptop (the ‘load’), it will result in a waste of electricity, but it would be a very, very small amount. Also, it won’t cause any sort of damage to the charger.
