Can a faulty battery cause my laptop to shutdown even on AC line ...
Turn on and off the computer (properly) and then replace the battery and charge it up. If this doesn''t help, you might have a defective battery. However, in normal circumstances, you should be able to remove the battery/charger as long as one or the other is present (a computer only needs one power source, two is helpful in case one fails.)
Battery charging question
I am trying to check that my stator is charging my battery. I checked the battery with the motor off and it registers around 12.4 - I started the motor and let it run for about 3 minutes then checked it again and it''s jumping around from 13 or 14 down to around 5 or 8 and randomly back up again. I am wondering what could be causing this ?

Unstable voltage reading at mobile battery terminals
I just observed a weird thing. My mobile battery got swollen and I purchased a new one. Before putting new battery into the phone, I plugged the charger and measured the voltage at mobile terminals (the three terminals where we connect the battery) with a Digital multimeter and the voltage was quickly and randomly varying from 0 to 4.
MacBook Pro battery percentage jumping down and up
Recently, my 2011 MacBook Pro 13'' produces strange instantaneous jumps in battery percentage. Sometimes, when it is discharging, it drops by ~40% (and if it was near or at less then 40%, it shuts down unexpectedly), sometimes (both when discharging or charging) it suddenly increases by 40%.

Sometimes unknown glitches can prevent the battery from charging. An easy way to fix it is to power down your computer, hold down the power button for 15 to 30 seconds, plug in the AC adapter, then start the …
The Charging Cycles of Lithium-ion Polymer Batteries
By analogy, if you charge randomly, the number of times is uncertain. In short, no matter how a Lithium battery is charged, it is constant to add a total of 300Q to 500Q of power. Therefore, we can also understand this: the life of a Lithium battery is related to the total charge of the battery and has nothing to do with the number of charges.
Touchpad mouse unstable while charging
As you mentioned when you use the touchpad the cursor randomly jumps across the screen on your laptop. Try the steps recommended below. Control Panel -> Hardware & Sound -> Power Options -> Change Plan Settings (of current selected plan) -> Change Advanced Power Settings -> USB Selective Suspend Setting -> Disable (both)
Sudden Battery drop to 0%

Dead battery.; Dim lights. Flickering gauges. Any one of these symptoms can be a sign of a weak charging system. Your charging system is responsible for restoring the charge to your car battery after use and is tasked with providing power to your lights, audio system, and other electronics while your vehicle is running.
Armada (and QX) charging system problem fix
But the reference voltage is programmed in as 12.1 volts (read from the OBDII port) So the first problem is, the battery is fully charged anywhere from 12.4 volts for a factory new Nissan overpriced lead acid battery to 13.2 volts for a top of the line AGM battery. So your charging system will never fully charge your battery.
battery
The symptom of powering off suddenly at various charge states (sometimes 25% left, sometimes 75% left) is almost always a battery that can''t keep up with the designed current. Some times it''s physical damage from a drop, sometimes chemical damage from being in a car trunk, sometimes just an out of spec battery.
Battery charge suddenly drops from about 25% to 6%
Most laptop batteries report their designed and current full charge capacities, which indicate the degree to which the battery has degraded. You may want to replace the battery if it holds less than 60% of its original capacity; heavily-aged batteries are more likely to completely fail and stop accepting charges altogether.
