Hi,
Could someone recommend a small-sized battery 3V battery that could sustain 15mA current for several seconds?
Our application requires two RF end device to occasionally establish some connection, so that when A is transmitting, B needs to be in receiving mode. Although A’s transmission could be in brief pulses so that is would work with a CR2032 battery, B’s receiving mode cannot operate in receiving mode since this will lose most of the pulses from A.
For B to operate in receiving mode it would require a current of 15mA, and it should last at least for a few seconds (3~5). If we use CR2032 which has continuous rating of 0.2mA and pulse current rating of 15mA, how long can the 15mA current be supplied? I wonder if more three seconds is too long for it?
We also looked for non-coin batteries which are larger. There is a comprehensive list at https://en.wikipedia.org/wiki/List_of_battery_sizes. We examined:
We are especially interested in exploring the possibility of reassembling two of A23’s 8 cells to reach both our current and voltage requirement. Could someone help?

• AAAA battery: but its voltage 1.5V is smaller than our required 3V, although it has no problem of supplying current even up to 300mA, see Energizer E96.
• A23 battery: It has voltage of 12V > 3V we require, and has no problem of supplying 15mA current for extend period as shown by Energizer A23. However although its voltage is 12V, according to Wikipedia it is stacked up by 8 cells so I believe each individual cell should have voltage 1.5V. Then can we unwrap an A23 battery and put two of its cells together to reach nominal voltage of 3V, while still allowing 15mA continuous current?
