There is not enough information. It depends on the type of battery: chemistry, cells, size.

What is the charging current and voltage of 12v 180ah battry?

That would also depend on battery chemistry.


Will any 12v battery charge work?

According to the magnitude of said current will be the time needed for charging. For there to be a current flow to the battery, the charger must provide a voltage (voltage) higher than the battery, this is the reason why we can not charge a 12V battery from another. Or at least, could not, as we shall see later.


Can i charge a 12v 7.2 battery with an out 12v-300mA charger?

Yes, you can charge a 12V 7.2Ah battery with a 12V 300mA charger, but it may take a long time to fully charge the battery due to the lower current output. The charger will provide a safe voltage for the battery, but the charging time could be significantly extended compared to a charger with a higher current output. Ensure the charger is compatible with the battery chemistry to avoid any damage.


What is the battery light on for on your Chevy Astro?

The battery light comes on when the charging system voltage drops below 12V. If your light is on all the time, have your charging system checked because it probably is not charging the sytem.


What is the voltage of a Yamaha maxim battery?

Battery type: YB14L Initial Charging Rate: 1.4A 10 hours Specific Gravity: 1.280 Voltage should be at least 12V DC


What is the difference between 12v 7ah and a 12v 7ah 20hr?

12v , 7Ah means its the capicity of Battery , if load current is 1 amp then battery runs for 7 hrs. AH = Ampere* Current. 12v, 7ah 20hrs its shows load current is 7/20 amp.


Can you use and charge and battery at the same time?

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...


Can you charge a 7.2V battery with a 12V power supply?

Yes, you can, but you need to put a resistance in series with the battery to limit the maximum current, so you don't overheat and cook the battery. I tend to fast charge my batteries using a 12v light bulb / utility light to lower the current. The bulb will glow when the battery is taking heavy current, and as the battery builds up charge, the current will drop and the bulb will get dimmer and dimmer. I try to limit the current to 1/10 of the capacity of the battery Im charging if I can. Otherwise, I monitor it with an ammeter and voltmeter and watch the lightbulb. $.02 Ed N3SDO


How do you hook up 2 12v batteries to make 24v for a wheelchairAsk us anything?

An important proviso is that the Ampere rating of both batteries should be the same. Otherwise, the plate current of the smaller battery could be exceeded. If you hook the negative terminal of one 12V battery to the positive of the other, then the assembly will have an overall voltage of 24 Volts. Be careful when dismantling the set-up if you have to do for charging.


Is it suitable to apply voltage 12V 30mA to charge 4V 750mA battery?

No, the charging voltage needs to closely match the battery or BOOM!


Can a 12v 10amps battery charger be used to charge a 12v 88ah battery?

Yes, a 12 volt battery charger will charge a 12 volt battery. The 88 amp hour is the capacity of the battery. It means that you can draw a load of 1 amp for 88 hours, 2 amps for 44 hours, 4 amps for 22 hours or what ever combination you want that will result in an answer of 88.


Can you store a 12v battery on the ground?

yes but they should not be left out in cold weather and keep them away from any heat source or sparks like from welding etc if charging the battery the acid caps should be loosened to allow excess gas vent
