How long does 23a 12V battery last?
The 12V A23 Battery has a good shelf life of up to 3 years.
At what voltage is an A23 battery dead?
Since LR932 are alkaline batteries, A23 battery voltage also drops over time and when the voltage drops down to 6.0 volts, battery is considered to be fully discharged.
Is an A23 battery the same as a 21 23?
Guaranteed for 5 years in Storage: Duracell 21/23 alkaline batteries are guaranteed for 5 years in storage. #1 Trusted Battery Brand: This Duracell CopperTop 21/23 Alkaline battery is equivalent to A23, MN21, A23, E23A, R23A and V23GA.
Is A23 Battery same as MN21 23?

| Associated Battery Sizes: | 1811A, 23, 23A, 23AE, 3LR50, 8LR23, 8LR932, A23, E23A, GP23A, K23A, KE23A, L1028, LR23A, LRV08, LRVO8, MN21, V23GA |
What’s the difference between A23 and 23A batteries?
what’s the difference between the 23a and 27a batteries? The A23 is 2/100 of longer” and 9/100″ wider. So a 27a should fit where a 23a does fits in most cases, but not necessary the other way round. Both are 12V DC so no harm to a device if either battery fits and works in your device.

How long do 12volt A23 LEDs last?
mAh of 2 12Volt A23 batteries is = 50mAh * 2 = 100mAh current draw of 6 LEDs is = 20mA * 6 = 120mA So the batteries will last approximately: 100 mAh/ 120mA = 0.833 hour or (0.833 * 60 minutes) = 49.98 minutes (approx.)
How long does a 40 mA battery last?
Then your batteries will last 100 mAh / 40 mA = 2.5 hours or 150 minutes. This is pretty optimal. The batteries’ capacity is 1200 mWh, and the LEDs consume 384 mW, so with an ideal conversion you can get a little over 3 hours out of them.
What happens when you feed three LEDs to one battery?
Their low internal resistance will cause a current from one battery to the other. So feed three LEDs from 1 battery, and the other three from the other. Then you place all LEDs parallel, which means that you lose (12 V – 3.2 V) x 20 mA = 176 mW per LED in its series resistor, while the LED itself uses only 64 mW. Total power loss is more than 1 W.
