Do you mean you want to bias the tube at the grid (1) or with a battery at the cathode (2)?

(1) it would last many many months ... I check them every 6 months and they are OK. The voltage fades away slowly so you are on the safe side

(2) get a rechargeable (capacity = 10x the bias current) and you are fine "for ever"
