The AAs or AAA’s have more Ah capacity than a 9V, so will last longer. The 9V also wastes more energy when dropped to 5V.
Is a 9V battery more powerful than AAA 1.5 V battery?
Calculating Energy in an AA Battery
Using the same energy formula before, we can calculate the amount of energy in a single 1.5 V AA battery. Obviously, that calculates as 6X a single AA and just slightly more than 4X a 9V battery.
How long does a 9V last?
12 to 18 months
The 9V alkaline batteries and AA alkaline batteries generally last 12 to 18 months. Lithium batteries will usually last 5x longer than their alkaline counterparts, achieving around 5 years lifetime.
Can you use 9V instead of AA?
Yes. Each AA or AAA battery has 1.5V. to make 9V, connect 6 AA batteries in series. Do the same for 6AAA batteries.
How long do 9V batteries last in use?
Li-ion batteries have a nominal voltage of 3.6V and 3.7V. Rechargeable nine-volt batteries usually come in two options: these are NiMH and Lithium. Lithium batteries double the NiMH capacity. NiMH’s 9V battery capacity last for about four hours with the rechargeable Lithium lasts for 7 to 7.5 hours.
How long will AA battery last?
about 5-10 years
