Charging Voltage of the Alternator in a Toyota Hilux
The charging voltage of the alternator in a Toyota Hilux is typically around 13.8 volts. This voltage is recommended for charging the battery in the vehicle.
In some cases, the alternator may be set to charge at 13.9 volts. However, it’s important to note that the output of the alternator is fixed at this voltage and cannot be increased beyond this level.
If the alternator is not functioning properly, it may result in the battery not being charged adequately, leading to the battery light coming on as a warning indicator.

Is 13.7 volts good for alternator?
You should be getting 13.2 to 14.2 volts from the alternator which is able to both run the electrical needs of the vehicle and recharge the battery.
Is 14.3 volts good for alternator?
If the alternator is working well, your multi-meter should read somewhere in the vicinity of 14 volts (typically 13.8-14.2). If it is reading excessively higher than 14 volts (greater than 15 volts) it is possible that the voltage regulator on your alternator is faulty or going bad.
What is the safe charging voltage for a 12V battery?
Charging voltages range between 2.15V per cell (12.9V for a “12V” 6 cell battery) and 2.35V per cell (14.1V for a “12V” 6 cell battery). These voltages can be applied to a fully charged battery without overcharging or damage, since they are below the “gassing” voltage, and cannot break down the electrolyte.
Is 14.8 volts too high?
14.8V is quite high for a sealed cell. It will probably reduce the life of the battery. Boost max is typically around 14.2 and absorption around 14. You should check your battery specification.
What is typical charging voltage?
The voltage profile will depend on the specific battery, but for your typical iron phosphate batteries, the range is 14.4 ± 0.2V. In other words, you should monitor between 14.2V and 14.6V while the battery is actively charging. Anything less might just be a trickle charge, if it charges at all.
What’s a good alternator reading?
Look for an ideal alternator reading of around 12.6. Start the car, and look for a reading of between 14.2 and 14.7. A reading of over 14.7 means the battery is being overcharged, while a reading under 14.2 means the alternator is undercharging the battery.
Is 14.7 volts too high for alternator?
The multimeter should read between 14.2 and 14.7 volts. If the reading is higher than 14.7 volts, then the alternator is overcharging. Turn on the headlights and other electrical accessories. The multimeter reading should not change significantly.
How many volts should a Toyota alternator put out?
If the voltage remains between 13.7 V and 14.7 V, then the alternator is still charging the battery. If the voltage right after the engine starts never makes it above 14V but instead sits around 13.7V-13.9V, the alternator is getting worn out, and will probably fail soon.
What is the charging voltage for a Toyota Hilux?
The car has an 80ah AGM battery that requires a 14.7v charging voltage to stay full.
What voltage should my alternator be charging at?
about 13.5 to 14.5 volts
Charging output can be tested on a vehicle with a digital voltmeter. A good alternator should produce about 13.5 to 14.5 volts with the engine idling. If the voltage reading is low (12.5 volts or less), it indicates a charging problem but does not tell you what’s causing it.
