You need a 6 volt battery that provides at least 4-5 amps, but preferably 10 amps. I have used emergency light batteries where a charge would last an entire season. The coil should only take between 1-2 amps to fire correctly but its better to have extra amperage available.
Going by your serial number, you should have the Atwater-Kent timer. I’m supplying a photo of both timer types, you should have the one on the right.
