What is causing the battery to drain?


Running the car will drain the battery it if it's not charging ! An if your charging light is on it isn't charging ! Did you check power an grounds on the alternator ? There is a single heavier wire on the back of the alternator, this should have battery voltage ! You may want to take this to a ASE certified repair shop !
Functionality
With the ignition switch in the RUN position, voltage is applied through the warning indicator I circuit 904 (LG/RD) to the voltage regulator. This turns the regulator on, allowing current to flow from battery sense A circuit 35 (OG/LB) to the generator field coil. When the engine is started, the generator begins to generate alternating current (AC) which is internally converted to direct current (DC). This current is then supplied to the vehicle's electrical system through the output (B+) terminal of the generator.
Once the generator begins generating current, a voltage signal is taken from the generator stator and fed back to the regulator S circuit 4 (WH/BK). This voltage feedback signal (typically half the battery voltage) is used to turn off the warning indicator.
With the system functioning normally, the generator output current is determined by the voltage of the A circuit 35 (OG/LB). The A circuit 35 (OG/LB) voltage is compared to a set voltage internal to the regulator, and the regulator controls the generator field current to maintain the correct generator output.
The set voltage will vary with temperature and is typically higher in cold temperatures and lower in warm temperatures. This allows for better battery recharge in the winter and reduces the chance of overcharging in the summer.
Battery Positive Output (B+) Circuit 38 (BK/OG)
The generator output is supplied through the battery positive output (B+) terminal on the back of the generator to the battery and electrical system.
I Circuit 904 (LG/RD)
The I (ignition) circuit 904 (LG/RD) is used to turn on the voltage regulator. This circuit is powered up with the ignition switch in the RUN position. This circuit is also used to turn the charging system warning indicator on if there is a fault in the charging system operation.
A Circuit 35 (OG/LB)
The A (battery sense) circuit 35 (OG/LB) is used to sense battery voltage. This voltage is used by the regulator to determine generator output. This circuit is used to supply current to the generator field (rotor). The amount of current supplied to the rotor will determine generator output.
S Circuit 4 (WH/BK)
The S (stator) circuit 4 (WH/BK) is used to feed back a voltage signal from the generator to the regulator. This voltage is used by the regulator to turn off the charging system warning indicator. The S circuit is fed back externally on external mounted regulator generators.

  1. Check the operation of the charging system warning indicator lamp (instrument cluster). Normal operation is as follows:
    • With the ignition switch OFF, the charging system warning indicator should be OFF.
    • With the ignition switch in RUN and the engine off, the charging system warning indicator light should be on.
    • With the engine running, the charging system warning indicator light should be off.
  1. Verify the battery condition. Refer to Section 414-01 .

Stanley 450 amp how long does it takebto charge


Sealed lead acid batteries are at the heart of most jumpstarters, mobile power supplies and equipment with standby capability. Such batteries arrive in a wide variety of qualities and while not particularly unreliable they do tend to fail suddenly.

Most often it is leaving them in a discharged state for more than a few weeks that hastens the death of all lead acid batteries. Even leaving one in a half charged state for as little as a month will permanently damage the battery causing it to have a reduced capacity.



The instruction leaflets supplied with such equipment invariably say recharge should take place periodically and after every use.

Usually there is an indicator light to show when charging has been successful but an overnight charge should be sufficient for a simple top-up charge and perhaps 24 hours for a periodic charge.



Use a digital voltmeter to check the battery voltage after it has been off-charge for 24 hours. A young healthy 12 volt battery will read 13.2 volts. An older but still usable example will read perhaps 12.7. 12.5 volts could be usable but the battery is definitely past its best.

A 12 volt battery that has a voltage of 12 volts is only half charged and is practically useless...

Less than 12 volts after charging and it is ready for recycling.

I have a Advent 8315 the turns itself off when unplugged even when its fully charged


Try removing your battery, wait 30 seconds and plug it back in and see if it powers up. If not, take your battery out, put it in the freezer overnight, take it out and let it sit in room temperature for 12 hours and then put it back in ....DO NOT put it in right out of the freezer and into the laptop ...let it warm up .... after 12 hours, try it and see if it shows 0% and charging ...if it still shows 100% charged, your battery is shot. Let me know how it goes

Battery won't charge


only 2 things will prevent this, One , the battery is weak,, and won't take a charge or has one or more dead cells, ( to find this out, have it tested ,, do a LOAD test on the battery , this will let you know if the required amps are being built back up, a battery can read 12 volts and still be bad, ) even if a single cell is bad , its not going to charge correctly ,, once you have a known good battery in the vehicle, and all the contacts are clean and tight, start the motor, using a meter, place the test leads on the battery posts,, you should get a reading of 13.5-14.5 volts ,, if you don't you have an alternator problem

Will not start, battery related, was needing to be jumped so changed battery, started fine for a month and same thing again, except today it will not even jump start


while the battery has been charged, check for a voltage of 12- 12.5 volts,, then start the vehicle,, you should get a reading of 13.75- 14.5 volts , which would show the alternator and voltage regulator of functioning properly if not,, charge the battery and replace the alternator

24 volt charging problems .2 12 volt batteries 1 battery 16volts and the other about 9-10 volts


A 12 volt battery is actually 13.2 volts fully charged. If you are reading 16 volts, you are probably getting extranious voltage from the system somewhere, especially if the vehicle is running when you check the voltage. The alternator will put out about 15-18 volts to charge the battery normally, and yours may put out 28-32 volts to charge them in series, but the batteries, when disconnected, should never read more than about 13.2 volts each. Typically, it will read about 12 1/2 volts when disconnected. COMPLETELY DISCONNECT BOTH OF THE BATTERIES. If you still read 16 volts when it is disconnected, you must have a bad meter because the battery can't produce that much voltage, no matter what. (Six 2.2 volt cells connected in series inside the case.) Put the meter on a known good battery on another car that is not running and see if you get the same reading. It sounds like the other battery is almost dead, regardless, and it sounds like your series/parallel switch may be malfunctioning. (That is the switch that puts the battery in series to run the 24 volt starter, then puts the batteries in parallel to run the remainder of the vehicle on 12 volts. This is all assuming that you have a diesel vehicle with a 24 volt starter and that is why you have two batteries.
