Last week I replaced the batteries in my Aristo-Craft 27 MHz transmitter with new Panasonic AA cells from the dollar store. Hey, who could resist 4-for-a-buck, brand-name batteries? Today I replaced them with four more AA cells. All of them were shot after just one use. As this is the second time I have encountered this problem with dollar store batteries, I am passing this warning on.
If the frequency LED on your transmitter is flashing when you turn it on, or you are having problems with linking or radio range; replace the dollar store batteries with Duracells. Yes they cost more, but they work!
I have tried using the rechargeable type AA batteries, the same ones I use for battery power for train, 2400 style, I have 64 of them. They did not last very long in the TE transmitters; they just don’t provide enough constant output. Rechargeable batteries also seem to drain faster than regular AA batteries. So now I go to Costco and pick up a box of regular AA batteries, the box usually last around a year for all our regular AA battery uses. I have had those in my transmitters for up to a year with no issues, had the rechargeable drain and stop working in less than a week just sitting in the transmitter.
