In terms of the ah rating the answer would be yes. 20ah will last longer than the 12ah. It depends on whether the size of the 20ah, they are larger, will prevent you from using them.

Can you replace 12v 40Ah battery with a 12v 12Ah battery?

Yes, you can replace a 12V 40Ah battery with a 12V 12Ah battery, but it is not recommended for most applications. The 12Ah battery will provide less capacity and thus a shorter runtime before needing to be recharged. Ensure that the device or system can operate effectively with the lower capacity and that the reduced runtime meets your needs. If the application requires the higher capacity, it's better to stick with the 40Ah battery.


What is the difference between 12V 12AH Battery and 12V 15AH Battery?

The AH means Amp Hours and is a measure of how much electricity the battery can store. Thus if the 12AH and 15AH batteries were connected to THE SAME device (one after the other) the 15AH battery would run the device for longer than the 12AH battery.


Can you use a 12v 12ah battery instead of a 12v 8ah battery?

The Ah (amp hour) rating of a battery is a measure of it's capacity. A 33Ah battery, when fully charged, will deliver 33 amps for one hour, or 11 amps for 3 hours, etc.A 7 Ah battery will only last about 20% as long as a 33Ah battery.


What is the difference between 12V 7AH Battery and 12V 12AH Battery?

Both are giving the data about storage capacity of a battery. For Ex. 12V 7AH Battery will run 7 hours if you are driving the load of 1Amp continuously. But 12 12AH Battery will run 12 hours if you are driving the load of 1Amp continuously.


Can you charge a 12v 12ah battery with a 12v 7ah charger safely?

Yes, you can charge a 12V 12Ah battery with a 12V 7Ah charger, but it may not be optimal. The 7Ah charger will charge the 12Ah battery more slowly than a charger with a higher output. Additionally, if the battery is significantly discharged, charging with a lower capacity charger could take a long time and may not fully charge the battery if the charger cannot provide enough current. Always monitor the charging process to ensure safety.

Can I use a 12v 7ah battery instead of a 12v 12ah battery?

Yes, you can use a 12V 7Ah battery instead of a 12V 12Ah battery, but there are important considerations. The 7Ah battery will provide a shorter runtime and may not meet the power demands of your device if it requires consistent output. Additionally, ensure the discharge rate is compatible with your application to avoid damaging the battery. If your usage exceeds the 7Ah capacity, it may lead to quicker depletion and potential over-discharge.


Need a 12v 12ah battery to power a device that normally uses a 7 point 2v 1400mah li-on battery can it be done and would it be practical?

Yes. You will need a voltage regulator circuit to produce the 7.2v from the 12v source.
