Mike G. Are your battery cables still connected? I''ll bet they are. Try unhooking the cables and see if the problem stops. If the cycling is a internal overload in the charger that is tripping, the culprit could be the charger itself, a shorted cell or plate in the battery or a short in the charging system.

SOLVED! Battery needle hangs then jumps but everything fine?

14.xx to 15.xx volts -- Charging a battery isn''t 100% efficient, so a battery charger will put this amount of voltage into a battery to raise the SoC. And it will raise / lower the voltage between these parameters to do it (so if you''re in your vehicle, you may see it move a bit -- but not fluctuate wildly).

6 Frequently Asked Questions about “Battery charging current display keeps jumping”

Why does my battery charger needle keep jumping?

One such problem is the battery charger needle moving back and forth. Why is my battery charger needle keeps jumping? The battery charger needle keeps jumping because of a shorted cell, short in the charging system, internal overload, excessive drain current and faulty connectors. 1. Shorted cell:

Why does my Charger keep jumping right and left?

If it kept jumping right and left, it might indicate that something is providing erroneous reading to the charger. Therefore it is sometimes providing higher current and sometimes lower current. Any shorted component in the circuit can keep the needle jumping around. It is the most common cause. 2. Short in the charging system:

Why is my laptop not charging?

A feature of your laptop's power manager software that tries to prolong your battery's useful life by limiting charging cycles. Sometimes you can tweak this via settings by switching from a 'battery saver' profile to something else. A faulty power manager or battery driver. Performing an uninstall-reinstall can fix this.

Why does my car battery keep jumping right and left?

Ideally, it should move from right to left as the car battery charges more and more. If it kept jumping right and left, it might indicate that something is providing erroneous reading to the charger. Therefore it is sometimes providing higher current and sometimes lower current.

Why does my car charger trip after needle jumping?

If, after needle jumping, the charger trips, it is an indication that the car charger might suffer from overload. In that case, you have to carefully check the battery specifications and opt for another charger that matches the specifications. That is the easiest way to solve this problem.

Why does a car battery charger keep moving?

If the amount of current needed by the car battery is much higher than what the battery charger supplies, it will suffer from an internal overload. When this occurs, time and again, the car battery charger will try to supply a higher amount of current but will fail to do so. That is why; the needle will keep on moving back and forth. 5.
