Can you use a 16 or 18 volt battery in a 14 volt ryobi cordless drill?

Absolutely not! It is a 14 volt drill. Use a 16 or 18 volt battery will destroy the drill in short order. It will run but not for long.


How many hours can we run a 1500 watt item off of one 24 volt battery?

First the amperage of the 1500 watt device has to be established. I = W/E. Amps = Watts /Volts = 1500/24 = 62.5 amps. To answer this question the amp/hour rating of the 24 volt battery has to be stated. This is the capacity rating of the battery. Take that rating and divide it by 62.5 amps will give you the amount of hours that the battery will take before it drains and needs to be recharged.


Will it hurt a clock which is meant to run on a 1.5 volt battery to be run by a 6 volt battery?

it can get really hot and burn the circuit


How long can you run a box fan off a car battery?

Unless it is a 12 volt DC box fan you cannot run it at all. If it is a 12 volt fan the time it will run depends on it's size and at what speed you run it and the condition of the battery. All you can do is try it.


What amps could you run on 6 mm cable 240 volt?

10A


How many amps are in a 12 volt 225ah battery?

Batteries are not measured in Amps, but rather as Amps they can emit in an hour. The standard home unit for battery power is AH our Ampere Hour.At 12 volts the amps in your battery are then described in Ampere Hours or Amps per hour.From that we get that if the battery was plugged into a 12v device that drew 225 amps, your battery would run out in 1 hour.Similarly if it was connected to a device requiring 112.5 amps it would take 2 hours to run down.Wikipedia has stated that this is an approximation, that at really high currents (measured in how many Amps you are currently using) the battery life is shorter than expected and that the Ampere hour is generally supposed to consider a 20 hour cycle of discharge(therefore meaning lower amps per hour)This brings the battery back to it's "normal" drainage pattern.@ 12v and 11.25A your battery would take 20 hours to drain.


How long will a batery with 125 amp-hour rating run a 60 watt load?

assuming a 12 volt car battery, 60 watts/ 12 volts = 5 amps, 125 amp/hours / 5 = 25 hours of life.


Can you use a 3 volt battery to run an 8 volt motor?

You can but the motor may not run, however you will not burn the motor.


Can a 9 volt battery run a 12 volt fan motor?

Possibly but but not for long. The 12v motor will draw more current than the 9v battery can supply and the undervoltage will cause the motor to run hotter than normal thus shorting its usefull life.


Can you run 2 12 volt trolling motors simultaneously off a single 12 volt battery?

Yes but you will deplete the battery quickly.


What is carring capacity of 16mm cable twin earth?

64 amps. The longer the run the more volt drop you get, but generally 64 amps.


What causes the battery light to come on when the headlights goes on?

Your alternator may not be putting out enough Amps to charge your battery and run your headlights as well. You can test this by measuring the voltage from the battery with a multimeter. With the car running the volts should be around 14 or more on a 12 volt battery. Try it with the lights on too.
