What is the voltage? What's the difference between a 312 and 312a?

The voltage is 1.4v. I'm told there is no difference between a 312 and a 312a, also I received Rayovac a312. One person said it is only to create customer loyalty. Also they have 312 cells, some have 125, Thus the number designation.

there is no difference between a 312 battery and a 312a. It is a manufacturers designation only, The batteries are the same. Voltage is shown either as 1.4V or 1.45V. Both will work perfectly in hearing aids designed for size 312 batteries. One thing all battery manufacturers agree on is that you should let a new battery stand in the air for about 60 seconds before closing the lid and using the hearing device. They are all "Zinc-Air" and must be activated before use.

I looked around some online and it seems that -5 volts was used in the ISA bus. Being that buss is no longer used it would seem that voltage is no longer needed. Doesn't hurt if it's present or not.

The 3300 is higher amps. It is slightly larger, and heavier than the 3200. I have the ,3200 and am very happy with it. Works well, and much quieter than ISE.

Should be since the numbers 312 mean a common size. The power one P13 is the same as any other 13 such as Duracell or Energizer.

12volt auto 1141. Do not use the 1156, it will get to hot and melt the recepticle.

Yes, the ADT battery is 12V, 5AH with F1 terminals, which is the same as the CA1240. Though the Ca1240 is listed at 4AH, it is rated at 5AH, which just means that it will run a little longer. Sort of like getting a baker's dozen for ordering a regular dozen. There might be some slight dimensional differences, but not enough to matter.

Yes they are. 312, PR41, B312, B347PA, 312HP, 312A, 312SA, DA312H, DA312N, AC312E, P312, 312AC, EZ312, are all 312 or "brown tab" batteries

If it uses 2-2016's then use those because the voltage of two cells is required. The 2016 is half as thick(1.6mm vs 3.2mm) as the 2032. The 2032 is over twice the capacity (lasts 2X longer) than the 2016 (~200mAhr versus 90mAhr), BUT two 2016's is 6.4V, whereas a single 2032 will be just 3.2V. Blue and White LED's will most likely require 2x2016's, while red for example might be just fine (and work longer) on 1x2032. Sorry it isn't simpler. Unless you are having problems with batteries not lasting long enough I would go with 2x2016's as one person states and just get a bunch of them (they can be found pretty cheap nowadays).

Back of package says input voltage is 12V and the output voltage is 5V with port A at 2.1A and port B at 1.0A.

3.8v and 3.7v are approximate voltage measurements for the "same" voltage. They should work the same.

both are vertical for 15a applications, 20a will have one horizontal. a = amp

My system is not ADT so, I can't answer your question really. I just looked at the battery I had before and used it as a reference. It too was a 12v 5ah battery. Similar size with F2 terminals.

These work for hearing aids that require 312. 312A and 312 are compatable for 312 hearing aids. These batteries work great.

Hi Sandra,The 312 is the same as the 312A, it is just a different company. Another is a P312 and it is the same as the other two.Austin

I think 30310a uses proprietary breakers and q310a uses off the shelf 1" breakers so you could swap how it comes to something that fits YOUR configuration. I bought q310a and swapped out the double pole 220 breakers for 10 110 breakers because I had no need for 220 amp breakers in my situation. I think in 30310a you're stuck with how it is. I don't think one is better than the other in Florida or anywhere else!! The previous answers seem to confirm.

I've not heard of 13A or P13. I would ask where I purchased my hearing aids, about those type batteries. I do know that 312 are smaller than 13. Sorry I can't be more help.

I don't know, as my 312 batteries aren't rechargeable. Didn't know they made them! But agree with Anthony's answer - SHOULD work.
