Depends on how low the battery is but give it 10-15 minutes and it will be fully charged, assuming the alternator is working properly.
Depends on the battery. Several hours to overnight.
Your alternator has failed, and the battery has drained from running the vehicle without being able to recharge it. Replace the alternator and the battery should be fine.
About 3 hours, 1 hour is for an 80% battery charge
It typically takes around 1-2 hours to recharge a standard AA rechargeable battery using a battery charger designed for rechargeable batteries. It's important to follow the manufacturer's guidelines to avoid overcharging and damaging the battery.
Check your alternator, that would be the main problem i think because the alternator charges your battery when in use, and with a bad alternator, means that your car is runnin soley off the battery and does not recharge the battery. Look into getting a new alternator. try testing the alternator at a local auto parts store, another test you could do is start the vehicle , and while it is running take off the battery cables, if motor turns off immediatly then your answer is that you have a bad alternator
battery is low charge. Take it for a long drive, to take the load off the engine from the alternator charging it.
To calculate the time to recharge a 70Ah battery at 4 amps, you can use the formula: time (hours) = capacity (Ah) / charge current (A). In this case, it would take approximately 70Ah / 4A = 17.5 hours to fully recharge the battery, assuming 100% efficiency and that the battery is completely discharged. In reality, charging efficiency and battery condition may extend this time.
about 10-20 min 1 day(my ds said)
You have to look at the specs on your charger to know.You can buy chargers which claim they can recharge a battery in 30 minutes.Most will take around 30 to 40 hours in theory and about 40% longer in practice.Battery life depends on what you're using the battery for.
first unhook the battery cables and then take the alternator belt loose and then take the 3 bolts out that hold the alternator on and take the wiring harness out of the alternator and the red battery cable off and it's out.
You have to take out the battery and recharge it or replace it.
