I kinda wonder that myself...I am running my 12v LED computer fan from a 12v battery pack from my Ryobi drill with the charging cable inserted into the battery...it says its charging, and my fan is running...So, I will see if it doesnt explode...fingers crossed...
As long as both batteries are the same voltage, you can jump start with the battery. If you want to charge the battery then use a battery charger.
Yes, both batteries perform the same, but the 7ah battery holds more charge.
There are a couple of ways to charge a battery in a 2005 DeVille. You can use jumper cables with the use of another battery. You can also use a portable battery charger.
Yes, you can.
Before using a rechargeable battery for the first time, it's recommended to fully charge it to establish a full cycle and optimize its performance. Make sure to follow the manufacturer's instructions for charging times and methods to ensure the battery's longevity and efficiency.
If both batteries are of the same voltage (12 or 6) yes, you can use the charger. make sure that they are of the same voltage.
No
Yes, the amp hour rating gives you an idea of the capacity of the battery and charger. The charger and battery need to have the same voltages. i.e. dont try to charge a 6v battery with a 12 v charger. The battery will be charged until it is full.
Some car battery charges will not charge a completely dead battery. You need to find a type of battery charger that is designed to charge a completely dead battery. You can get around this by hooking a car with a working battery up to the dead battery with jumper cables. The alternator/charging system of the car with the good battery will charge the dead battery. Leave them connected for about 30 min, then disconnect and try to use the battery charger again. If it still won't charge, hook it up to the car with the good battery for a longer period of time.
If you aren't going to use the battery for a while or you're storing it, make sure the battery is over 40% charged before you put it away. When Li-ion batteries are stored out of charge for long periods of time, this can lead to an inability to maintain a charge once the battery is in use again.
wht type battery do you use
older cars had a generator ,not an alternator, but you can always use a battery charger to charge a battery
