A car battery should read 14.4 to 14.8 volts DC while charging. In cold weather, the voltage can reach 14.8 volts, but it may drop to 14.4 volts as the engine warms up.

I see yours is going up to 15 / 15.1 v on your sg. Did you measure it at the battery/alt as well? Curious how high it is actually going / is it indicating slightly less on the sg? I wonder if 14.8 actual is enough to kick them off, that might not work so well for me. OP: how long are your plugs staying on? Do you monitor the voltage? Any chance
Customer ServiceCheck if it is a BMW OEM battery, if not it has likely been replaced prior to you purchasing and if the battery is aftermarket it isn''t able to be registered to the vehicle. Registering the battery replacement in the vehicles software is done
Customer ServiceSo 14.8v shortly after starting means that the battery is probably fully charged already and the voltage should then drop to around 13.6-14 fairly quickly. If the battery seems
Customer ServiceA higher voltage means energy is being driven into the battery at a higher rate. 14.8 volts would be appropriate for a battery with less than an almost full charge and/or high electrical load. If the battery is at or very near full charge, it is appropriate for the charging voltage to be lower and that could explain the low 13 something voltage you observed.
Customer ServiceThe completely charged voltage should be 4 x 4.2 = 16.8v for a 4S lipo. If you''re not going to be using it for a few weeks, I''d leave it where you have it and try to completely charge it before you''ll actually use it. The 3.7v/cell based voltage is called the ''nominal'' voltage like 1.2v/cell is called the voltage for AA cells. It
Customer Service$begingroup$ That''s because the battery is full. A small amount of current will quickly raise the voltage to 14.8 volts, at which point the PWM charger quickly stops charging. Then the voltage of the battery drops immediately to
Customer ServiceIf the battery is good and strong you should see 13.8 - 14.8 volts (system voltage) for a while; it may then ramp down to the 13s and stay there depending on electrical loads. A fully charged "12 volt" battery will show 12.6 volts when disconnected from anything for a half hour. Anything below 12.6 is either a bad battery or something wrong with the charging system.
Customer ServiceWith the engine off, the fully charged car battery voltage will measure 12.6 volts. This is known as "resting voltage." When the engine is running, battery voltage will typically rise to 13.5 to 14.5 volts. The battery is boosted to these higher levels by the alternator.
Customer ServiceHello. My HP laptop - 15-bs169ur. The battery is dead. I bought a new battery. Old 10.95 volt battery. 3 cells. I bought a four cell battery, but 14.8 volts. Can I use a 14.8 volt battery in this laptop? Thank you!
Customer ServiceThe charging system in most cars will generally produce a voltage between 13.5 and 14.4 volts while the engine is running. It has to generate more voltage than the battery''s
Customer ServicePart 3. What is the charged voltage of an AGM battery? The charged voltage of an AGM battery is the voltage it reaches when it''s fully charged. It''s the maximum voltage the battery can hold. This voltage is typically around 14.4 to 14.8 volts. It''s important to note that the charged voltage can vary slightly depending on the battery''s
Customer ServiceIf the battery state of charge (SOC) is high, the PCM will target a voltage about .5V over battery voltage (typically around 13.2V)--so just a little current is pushed into the battery (so it doesn''t overcharge). If your battery has
Customer ServiceI just went to an autozone, they did the battery test where they checked my alternator and battery. The battery was putting out the right voltage but when turned on the battery percentage isn''t at its performance level. The battery
Customer ServiceSince I''ve had it, the battery/charging voltage consistently reads 14.8 volts. I noticed a couple of times when the a/c fan would slow, and sure enough, when I checked, charging voltage was a normal 14.0 volts. Anyone got a similar voltage reading on their Renegade? I''m thinking I have a faulty alternator/regulator (assuming its
Customer ServiceThe charging system in most cars will generally produce a voltage between 13.5 and 14.4 volts while the engine is running. It has to generate more voltage than the battery''s rated voltage to overcome the internal resistance of the battery. This may seem strange, but the current needed to recharge the battery would not flow at all if

Customer ServiceSo I changed an attribute in the POW for max charging voltage. If you have a lead acid battery then it is fine to charge @ >14.8. You can still set it lower so it does not reduce your enjoyment of tunes in winter . One of each.

Customer ServiceWhat Is 4 Cell LiPo Battery Voltage? 4S LiPo indicates 4 LiPo cells connected to the battery. Every individual cell has a nominal voltage of 3.6-3.7 volts. Thus, a nominal voltage is around 14.8 volts, and capacity usually
Customer ServiceDepending upon ambient temperature, charging voltage generally varies between 14.8 and 13.5 volts. The actual charging voltage designed into a voltage regulator is dependent upon factors such as how far

Customer ServiceSo 14.8v shortly after starting means that the battery is probably fully charged already and the voltage should then drop to around 13.6-14 fairly quickly. If the battery seems to charge up very quickly compared to what it used to, then it implies that its capacity is much less.
Customer ServiceQ : 14.8 volts sont-ils trop élevés pour une batterie LiFePO4 ? R : Oui, 14.8 volts dépassent la tension de charge maximale recommandée pour la plupart des batteries LiFePO4, qui devrait être d''environ 14.6 volts.
Customer ServiceIt should be between 14.6 to 14.9 V to battery get charged. If it goes above 15 V then you should check your alternator. It depends on temperature and battery type. My OEM battery is AGM and at 30 degrees F, it runs at 15.3 volts.

The original battery in the laptop is a 10.95 volt. My concern is the step up in voltage going to damage the laptop? Is the original 4 cell 41 w-hr a 14.8 volt battery?
The actual charging voltage designed into a voltage regulator is dependent upon factors such as how far the alternator is located from the battery and the ambient air temperature surrounding the battery as calculated by the PCM. Under normal operating conditions, an alternator should maintain about 14.2 volts at 70° F ambient air temperature.
Worst source of charging system I.R. drop is those "cut and install" battery terminal ends. on making sure all connections are clean and tight, including a good engine ground (and also the back-of-engine-to-firewall ground strap) before attempting any regulator adjustments. Anything between 13.8 volts and 15 volts is safe.
