Understanding whether 14.7 volts is a good charging voltage for batteries, particularly 12V lead-acid batteries, is essential for maintaining battery health and longevity.A charging voltage of 14.7 volts is generally considered acceptable, especially during the bulk charging phase, but it can vary based on battery type and condition.
Another possibility (just wondering) if Tesla is going to just make a designated portion of the main pack to just provide a 48 Volt current source (tap), which would mean that a 48-52 volt charging system would not even be needed at all (like the 12-14 volt charger circuits in the battery pack penthouse configuration they have now). Software and the battery
The voltage in the picture is about 14.5v, the next tick mark is 16.5v. What you are seeing is normal. The alternator will cannot carry the load of the intake heater and glow plugs. So while they are one the voltage will be low, once they finish there thing the alternator will run voltage up over 14 volts until the batteries are recharged. Then
I pulled the battery and charged it. I checked the voltage at the alternator (14.4) and checked the status of the diodes (all good). I would have liked to replace the positive battery cable terminal but it''s a snug fit and the bolt is frozen. So, I cleaned it. After sitting overnight the battery is at 12.23 volts. The car starts right up and

A standard or new good battery voltage is 12.6 when the car battery voltage at rest. The battery voltage when running can go up between 13.5V to 14.5V. It is because the battery is being charged by the alternator, which boosts the battery to be able to power the electrical components without draining. The standard volt for a car is 12.6 volts
There are two things that you are looking for. The charging voltage should be between 13.9v to 14.4v. Also the voltage at the battery and the voltage at the alternator should be within 0.5v of each other. If the voltage at the battery and alternator don''t match. For example the battery reads 12v and alternator reads 14v. This means that there
My guess is that you checked the car voltage, running, battery disconnected. The alternator was putting out 14.2 volts. A battery will never put out more than about 12.8
For instance, the Toyota Prius has a battery voltage of about 201.6 volts (Toyota, 2020). Battery Type: Traditional car batteries are typically lead-acid batteries. They store energy chemically and release it as electrical energy when needed. Hybrid batteries often use nickel-metal hydride (NiMH) or lithium-ion technologies, which can handle higher voltages and
Many LiFePO4 battery manufacturers recommend 14.6 volt absorption. But, that singular recommendation doesn''t account for numerous factors like managing a larger system, battery longevity, and more.
If I let the car sit for a few hours, the resting battery voltage is 11.6-11.8 volts. Starting the car in the morning the voltage quickly goes to 14.0 - 14.3 volts. All good at this point, however. After driving for awhile and especially during the day in hot Las Vegas weather, the battery voltage will typically run about 12.5-12.6 volts. It
What is the dangerous low voltage i should avoid reaching? So say you make it down to 43v with your 14s battery; 43 divided by 14 puts the individual cells at 3.07v. You''d have to be down to (2.5*14=)35 volts to be "unsafe" and that''s not happening. My cutoff at 42.5v is still 3.03v per cell. There is the potential for an imbalanced cell to be much lower and sneak past the average, but
The 12 volt battery is charged by the 14 volt power module only, does not get power directly from the battery charger as a low voltage but as a high voltage converted in to low voltage. There are many modes of operation for the 14 volt power module to charge the 12 volt battery. Battery Sulfation Mode, Normal Mode, Fuel Economy Mode, Headlamp
