I buy alkalines at Dollar General or HF. Had some DG's leak in my battery razor. Made a mess. Took pics and emailed to DG. Pointed out that other mfg. state that they will replace damaged item. DG sent me a new razor. True story. I was able to clean corrosion from old one, now have spare. I try not to leave batteries in an appliance, or check on them occasionally for corrosion.
