If it is totally dead charge it for 2 hours at 10 amps.
Yes, a 12V 10A battery charger can be used to charge a 12V 88Ah battery. However, charging time may be longer than with a higher amperage charger. It is important to monitor the charging process and ensure the charger is compatible with the battery's requirements.
can a 12v lawn mower sealed battery be charged with 12v battery charger use on cars
No
To charge any battery the voltage of the input must be more than the battery's output.
No.
No
the time it takes to charge a battery is governed by the amps the higher the amps the quicker the recharge time. Excessive charge rate will 'cook' the battery and it will be scrap.It might even explode and cover you in acid.Use a proper charger and check the correct charge rate for your particular battery.
No, you need at least 12v to charge 12v. Most alternators charge at 13-14 volts.
6volts 2amps for 6 volt battery, and 12 volts 6amps for a 12 volt battery. Don't charge a 6 volt battery on the 12 volt setting or it will explode!!!!!!!!! you're ok going the other way though.
yes
To calculate the wattage needed to charge a 12V battery in 6 hours, you need to know the battery's capacity in amp-hours (Ah). Once you have the Ah rating, you can use the formula Watts = Volts x Amps to determine the wattage required for charging. Multiply the battery's voltage (12V) by its capacity in Ah, then divide by the charging time in hours (6 hours). This will give you the minimum wattage needed to charge the battery in 6 hours.
