Transmitter battery ID

anyone know the battery for this TX module?

Looks like a Perdix TX module but has more metal trim. it's not a CR2 which is too long.

that is the original version of the transmitter that came with the first gen AI oceanic computers like the datatrans plus. it uses silver oxide LR44/357 coin batteries (i think 3, might be 2)

i have found the battery life and signal strength are not as good as the newer version.

@guruboy

Is it marked on the battery cap end with FCC ID MH8A, like the current transmittters?

Yes

The TX is the early version of the Oceanic TX and takes a 1/2 AA battery.
