In the morning, I turn the key over and see my battery line just above the split between 9 and 14. I start the engine. Needle drops to zero, moves back to where it was with
Customer ServiceI just bought a float charger from Harbor Freight for my car battery. I hooked up a voltmeter with no other load and the output voltage reading from the float charger was rapidly fluctuating back and forth from 0 volt to 2V and sometime up to 8V but never reached 13+ volt like it was supposed to.

Customer ServiceRecently, I''ve observed that the charger''s DC amp "jumps" every 4-5 seconds and then repeats. To be exact, the DC amp starts around 1 amp and gradually increases to 1.5 amps, and then suddenly jumps to 6 amps, and then comes back and start doing this again.
Customer ServiceWhen in pre-charge mode charge to 3.1V, the voltage will jump back and forth around 2.6V and 3.1V, then jumps to 2.6V and rise again shown as below. And current jump to 2A abnormally. Can you know the reason of the jump? Two logs are attached, log 1: when 25℃, current jumps to 2A, log 2: when 5℃, current jumps to 1.571A.
Customer ServiceWhen you jump it the other vehicle makes a connection through the jump lead. When you go solo there is no ground to make your starter work. Test it by running a jump
Customer ServiceBattery capacity and state of charge have a direct impact on the current variation of a lithium-ion battery. As the battery reaches higher states of charge during charging, the current gradually decreases. Similarly, during discharging, as the battery''s state of charge decreases, the current also decreases.
Customer ServiceThe data looks to show charge current begin to decay as if it is in voltage regulation phase. Then charge current attempts to increase back to fast charge current. Typically this would indicate the battery regulation voltage has been changed.
Customer ServiceWhy 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: The charger needle denotes the current being supplied to the car battery. Ideally, it should move from right to left

Customer ServiceI just hooked up my inverter charger multiplus 3000w along with a Victron solar charge controller in my RV. whenever my multiplus charger is on Absorption the battery voltage jumps back and forth between 13.4 and 15.4 very fast. It stays at a constant voltage when in bulk charge.

Customer ServiceThe needle was moving fine, but has now started to ease up to 0 (Charged), quickly drop back to about 6 and ease back up to 0. I''m guessing the voltage reading on the needle is how much is being applied to the battery, and when its fully charged it stops at 0.

Customer ServiceWhen you jump it the other vehicle makes a connection through the jump lead. When you go solo there is no ground to make your starter work. Test it by running a jump cable from the battery neg terminal to a good clean spot on the engine. If it fires up then check / clean the battery neg wire to engine terminals. By the way, never

Customer ServiceOnce the charger commences charging you can remove the jump battery and leave the flat battery to be charged. A few reasons why the charger is not charging the battery: The charger itself is not working; The battery will not take a charge, the battery can be 'dead'. If you can, connect the charger to another battery, just to see if it is working.
Jump starting does not charge your battery. It only supplies the current to get the engine started and a residual charge. You needed to have the battery fully charged at least overnight. Its possible now though that the battery is damaged and it might be best to just replace it. Nothing much works at that temp though.
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.
The most serious reason why a battery drains while charging could be that the sub-board is bad. Since the charging port is connected to the sub-board, charging issues like overcharging, overheating, and voltage fluctuation can cause damage to the sub-board.
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.
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:
