Don’t know if anyone else is having a problem with these, but put a set of new ones in my Simpson 260 last summer and just found that they have leaked. Will have to replace the contacts as they are fairly well eaten. Had a problem with them years ago and stopped using them. Heard that they had gotten better, so got some at COSCO and now wish I hadn’t. Back to Eveready or Energizers I guess. Just thought I should let you all know.
