Unlikely.
First off, I can't think of any battery chemistry that would reach 5V, which makes me think that it's not a charger but simply a power supply that you are talking about. And while it's possible to charge a battery that way, the power supply won't have any means of stopping the charge once the battery is full. So unless you're monitoring the charge by some other means, there's a real risk of overcharging and damaging the battery.
Secondly, if it is a charger, using a charger rated for a lower voltage than the battery, it'll stop charging too soon, leaving you with only a partially charged battery.
Third, while not impossible, 7 amps would be a lot to push from a 5V source. If it's correct, pushing 7 amps into a 0.6 amp-hour battery really isn't a good move. It'd be a too high charge rate.
What else can I help you with?
Can you use any car battery charger to charge a battery from an automatic car?
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.
Can you use a 12 volt charger to charge 14.4 volt battery?
It is not recommended to use a 12 volt charger to charge a 14.4 volt battery as the charger may not provide enough voltage to fully charge the battery. Using the correct voltage charger will ensure efficient and safe charging of the battery.
Can you use a 12v charger to charge a 14.4v battery?
No, you must use a 14.4 volt charger.
How do you get a completely dead car to charge?
Use a battery charger.
Can you use a 6 volt battery charger to charge a 12 volt battery?
No it will not work
Can you use 12V charger to charge 10V battery?
You can but you can alos easily overcharge the battery.
Can you charge a 6 volt battery with a 12 volt battery charger on slow 2amp charge?
It is not recommended to charge a 6 volt battery with a 12 volt battery charger as it can damage the battery. The higher voltage can overcharge the battery and cause it to overheat. It is important to use the correct charger with the matching voltage to prevent damage to the battery.
How do you charge battery in a 2005 DeVille?
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.
Can you use a 12V 7Ah charger to charge a 12V 26Ah battery?
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.
Can I use any adaptor to charge a battery?
No. A battery charger has to be specifically matched to the batteries to be charged.
Is a 2 amp battery charger the same as a 1 amp battery charger?
No, a 2 amp battery charger has a higher charging capacity than a 1 amp battery charger. This means the 2 amp charger can charge a battery faster than the 1 amp charger. It's important to use the appropriate charger to avoid damaging the battery.
Can you charge a dead car battery on a battery charger?
Yes, you can even charge it on the vehicle. Make sure you charge it slowly and either use an automatic shutoff charger or pay close attention the the charge. Do not overcharge. It is best to charge it slowly with a 10 amp or lower charger. Make sure the battery cables are clean and tight.
