I've just been using 40 packs of GP Ultra Alkaline most of the time in my HR92's and DTS92E with no problems at all. They seem to last about 1 1/2 years in my HR92's, given that I have them all set in the more battery hungry Stroke 1 mode, and over 2 years in DTS92E's. (I've only changed the batteries in my DTS92's twice - and I've had them for 5 years!)
