Car battery at 12.2V: replace? | BobIsTheOilGuy
If not then the battery is fine and may just be under charged. Also check the voltage it snaps back to after 30 seconds or less of cranking. If it goes back to 12ish right away then investigate the alternator. it has always tested strong. Their OEM replacements are the only ones I can still find with 84-month warranties; all others max out

A second problem might be that the battery is quite small. Only 8 amp hours. A car battery is probably around 50 amp hours. If you apply a car battery charger to it, the car battery charger could have too high current at which it transitions from absorption charge to float charge. Ideally battery chargers would let you specify these four

Battery...CCA drops but the voltage stays at 12.7...WHY?
The battery is less than (get this) 3 weeks old. It''s an Advance Auto Gold Star Battery with 770CCA (their top-of-the-line). Could it be a defective battery? I spoke with a mechanic and he stated that since the battery was fully charged, but the CCA was only 200, there''s a defect in the battery cells. Is that correct? HELP!

Is 12.7 volts while the car running okay?
A fully charged battery will put out 2.2 volts per cell or 13.2 volts. While the car is running the alternator should put out in eccess of that number of volts.

One of your users suspects that the battery in their laptop computer is failing. You test it by using a known good power adapter long enough to receive a full charge. The battery reads that it is fully charged in Windows. You then disconnect the laptop from its power source and wait to see how long the battery lasts. The battery dies after only about 15 minutes.

Car battery test says it is Good, but can''t charge above 12.45V
As the battery is used and goes through its recharging process, it can sulfate which is to mean, sulfur crystals will collect on the lead plates and limit the ability of the battery to charge up fully. If the battery is somewhere in between new and five years old, you''ll see a lessoning of how well the battery can be charged.

Battery voltage between 13.6
Because of the laws of physics, a battery can never charge at it''s voltage potential, it must be charged at greater than it''s final potential. Perhaps potential is not the technically proper word. For a lead-acid battery, it''s charging at 14.4V, but once fully charged, the resting voltage of the battery itself will drop back down to about ~12.7V.

Quick Answer: What Should A Fully Charged 12V Deep Cycle Battery
Once the battery is fully charged it can be maintained by applying a charging voltage of 2.24 to 2.25 volts per cell (13.4-13.5 for 12volt and 26.8 to 27.0 for 24volt). This is called a "Float" charge. The voltage reading of 12.4 volts will indicate that the battery is only 75 percent charged. A meter reading of 12.2 volts or 12.0 volts

What should a fully charged battery read?
The reading for a fully charged battery should read 12.6 to 12.7 volts, some AGM batteries can be 12.8 volts, if you have a reading which is showing -12.6 or -12.7 then you have the probes the wrong way round. As mentioned previously, a fully charged battery is 12.6 to 12.7 volts and the resting voltage, ideally should be no lower than this.
What is a 12 volt battery?
Various sources describe charge voltage in two different ways, so we’ll cover both here. The voltage of a battery gradually decreases as it discharges Most batteries actually have a voltage slightly higher than what you see on the label. 12 volt sealed lead acid batteries usually, in reality, are 12.6 or 12.7 volt batteries when fully charged.
What is a battery charge voltage?
The charge voltage refers to this ‘real’ voltage when the battery is fully charged. Voltage then is a measure we can use to see if a battery is fully charged, but only if we know what the real voltage should be, not what is on the label.
What is a normal battery voltage?
We noted that 12.6-12.7 Volts is the normally voltage for a fully charged battery, and showed which voltages correspond to which approximate charge % level. Be aware with analysing voltage – it doesn’t show the health of the battery per se, it just shows how much charge is in the battery at the moment you measure.
What is a fully charged car battery?
As mentioned earlier, a fully charged car battery typically measures around 12.6 volts. However, the voltage of a car battery can also be used to estimate its state of charge. For instance, a voltage reading of 12.2 volts or lower indicates that the battery is discharged and needs to be charged.
Is a 12 volt battery half charged?
A rule of thumb is that a battery reading 12.4 volts is half charged and a battery reading of 12.2 volts is flat, below 12 volts is classed as discharged and the lower the voltage drops is deep discharge and sulphation will occur. Anything less than 12.4 volts we would recommend placing on an appropriate intelligent battery charger to fully charge.
