You can use ANY 18V charger, as long as the Amperage of the charger is equal to, or greater than the device’s Input value. 3x 10.7v is 32.1v so that is the minimum voltage for a completely ‘dead’ 36v battery. … Your 12v charger will just kill it even deader!Mar 25, 2020
You cannot use the 12V charger directly to charge a 24V battery. To do the task you will need a boost converter capable of generating output voltage greater than 24V.
Thereof, What voltage should I charge my 18v battery?
18 volts
Also to know is, How do you charge a 24v battery?
Subsequently, question is, Can you charge 18v battery with 24v charger? Originally Answered: Can you charge an 18v battery with a 24v charger? You can charge the 18 volt battery by 24 volt charger, but after some time due to heating and over charging electrolyte present in battery starts vaporization, by which your battery cells damaged.
Also, What is the voltage on a fully charged battery?
12.6 volts
Does amperage matter when charging a battery?
If the power supply can supply more than 2.1Amps this doesn’t matter as the product will only take 2.1Amps. If the power supply can only supply 1 Amp in this case then either the product will fail to work/charge or charge slowly as it can’t get enough current (or power) to charge the battery.
How many amps do I need to charge a 12 volt battery?
25 amp
What happens if I use a lower voltage charger?
Originally Answered: What happens if you use a higher or lower rated (voltage) charger on my laptop? Lower voltage charger will do no harm but may not deliver enough charge. Voltage too high can do significant damage if the device to be charged lacks overvoltage protection.
Should I charge my battery at 2 or 10 amps?
Consequently, when trying to charge a larger battery at that rate, it will take a very long time and the battery may discharge at a greater rate than the 2-amp charge can provide. It is better to charge a deep cycle battery at a higher charge rate like 6-amps, 10-amps or higher.
Can I use higher amperage charger?
This isn’t as simple as just “charge your device with the charger it shipped with.” You can actually use higher amperage chargers, like the kind that come with tablets, to get your phone charged up in less time than it would if you charged via USB or using the charger the phone came with, and it won’t cause a problem.
Can you charge 24 volt battery system?
For a 24 volt battery bank, there is two way to charge your batteries. You can use a 24 volt charger or a 12 volt two bank charger.
How long does it take to charge a 24v battery?
18 hours
How many volts will a fully charged battery cell have?
2.2 volts
What is the maximum charging voltage for a 12 volt battery?
14.2-14.4 VDC
Does amperage affect battery life?
Yes, the battery performance will degrade if it is charged very rapidly. Charging with smaller currents will invariably extend cycle life. A good thumb rule is to use a max current equal to the ‘stock’ charger, i.e. the current rating of the charger that came with your device.
What is the voltage of a fully charged car battery?
12.8 volts
How long does it take to charge a battery at 10 amps?
about 6 hours
