But, you don’t have to wait till you get a dedicated charger before you can charge your battery. You can use a 12 volt charger to charge your 8 volt battery.
How many volts are needed to charge a 12V battery?
12.9 volts
A: A 12V car battery can be safely charged over a range of voltages. It needs at least 12.9 volts to charge, but at this voltage the charge rate of an automobile battery is very slow. A car battery can be charged safely at high voltages as long as the battery is not fully charged.
Can you use a 6V charger on a 12V battery?
No, there is not enough voltage provided by 6 volt charger to be able to charge a 12 volt battery. No, there is not enough voltage provided by 6 volt charger to be able to charge a 12 volt battery. Depending on the batteries chemistry a 12 volt battery will actually have different “full” and “charge” voltages.
Can a 9v charger charge a 12V battery?
You cannot use a 9 volt charger as it will not be capable of providing enough voltage. A 12 volt battery (I’m using a lead-acid battery as an example) needs a charging voltage of about 13.5 volts to properly charge the battery. The standard charge level typically used in automobiles is 13.7 volts.
How many amps do I need to charge a 12 volt battery?
Most battery manufacturers recommend sizing the charger at about 25% of the battery capacity (ah = amp hour capacity). Thus, a 100 ah 12 volt battery would take about a 25 amp 12 volt charger (or less).
Should I charge my battery at 2 or 10 amps?
It is best to slow charge the battery. Slow charging rates vary depending on the battery’s type and capacity. However, when charging an automotive battery, 10 amps or less is considered a slow charge, while 20 amps or above is generally considered a fast charge.
Can I charge a 12v 7ah battery with a car charger?
I recently bought a transferable car battery charger for when my car’s battery is dead. What I want to know is if I can go ahead and use that car battery charger to charge my 12v 7ah battery for my scooter. Yes you can. A 12v charger can charge any 12v battery.
Can you charge an 8 volt battery with a 6 volt charger?
You can use a 12 volt charger to charge your 8 volt battery. You can as well charge a 6-volt battery with an 8 volt battery charger. It’s also possible to use a 6v charger for an 8v battery provided that the output voltage on the charger is higher.
Can you charge a 12V battery with a 24v charger?
No, strictly NO ! Any good charger has both current (for deep discharged condition) and voltage( at the end of charging) limits set inside. Therefore obvious that 24v system can’t charge 12 v battery. Any battery has manufacturer s recommended final charging voltage which is about 10 to 15% more than rated voltage .
Can I charge a 6V battery with a 9V charger?
You can charge 6 V battery from 9 V charger, but you will need the following in designing the charger circuit: Limit the charging current within the acceptable limits for battery. Limit and cut off the charging voltage when necessary once the battery is fully charged.
What happens if I plug 9V into 12V?
If you have a 12V adapter, you might wonder whether you can use it to power your 9V guitar pedals. In most cases, you cannot use a 12V adapter to power a 9V guitar pedal. Using a 12V adapter on a pedal designed to only handle 9V can completely destroy it.Those pedals will work perfectly fine with a 12V adapter.
Can I use 10v charger to 12V battery?
Too high current will cause the temperature to rise and may rupture the cell. Too low current will just not charge the batteries. This current is determined by the size of the battery current rating. 10% charging current will be safe for most batteries, 1% can be safe for trickle charge.
Can I use a 9V adapter for a 12V device?
No. The power supply is capable of producing one ampere, if the device draws that much, but it won’t force that much current through the device. As long as the voltages are matched, there’s no harm in using a power supply with a higher capacity (better higher than lower).
How long does it take to charge a 7ah battery?
The way you figure a rough time estimate using a 600ma charger is (7ah = 7000mah) 7000mah/600ma = 11.7hr. A 1amp charge would indicate 7hrs in the same way.
How long does it take to charge a 12-volt battery at 10 amps?
4-7 hours
A 10 Amp charge will take 4-7 hours to fully charge the battery, a 2 Amp charge will take 1-2 days. You don’t need to charge the battery to start the car.
What type of battery charger do I need?
As a rule of thumb your battery charger should be a minimum of 10% of the Ah rating of the battery. E.g A 100Ah battery would require a 10 Amp charger as a minimum. To prevent overcharging you should keep the charger size to within 20% of the total capacity.
How long should you charge a 12-volt battery at 2 amps?
If you’re using a 1-amp charger and your battery is completely dead (0 amps), it will take 48 hours. However, if you’re using a 2-amp charger, it will take 24 hours. Each amp that the manufacturer rates the charger for will restore one amp in the battery per hour.
How long does it take to charge a car battery at 8 amps?
about 10-24 hours
Charging a regular car battery with a typical charge amp of around 4-8 amperes will take about 10-24 hours to charge it fully. To boost your battery enough to be able to start the engine, it would take around 2-4 hours.
What charger do I need for a 12v 7AH battery?
As a general rule of thumb when selecting a charger for a lead acid battery, match the voltage and use one that is no more than 20% of the capacity rating of the battery (at a 20hr. rate). Example; to charge a 12 volt / 7.5Ah battery, select a charger with a maximum charge output of 1.5 Amps (7.5 x 0.20 = 1.5).
How long does it take to charge a 12 volt 7AH battery?
How long will it take to fully charge a 12 volt 7AH SLA battery with a 20-watt 12 volt solar panel? – Quora. 4.2 hours.
Can I replace a 12v 7AH battery with a 12v 9Ah battery?
Simply put both versions will fit in your application and will work fine. As the dimensions of the 12 Volt 7Ah battery and the 12 Volt 9Ah battery are exactly the same, they are interchangeable. Amp-Hours basically show how much energy a battery holds.
