I usually use Duracell or Energizer batteries. I got some Rayovac
batteries because they were cheaper. I figured that they were about
the same, and you are paying for Duracell and Energizer advertising. I
had the Rayovac batteries in two Maglite flashlights. Both started
getting dim, so I opened them up to change the batteries. The Rayovac
batteries had leaked and ruined the flashlights. I contacted Rayovac
- they said that they were reimbursing me for the flashlights and
today I received new batteries from them.

I'm afraid to use the replacement Rayovac batteries - they might leak
and ruin something else. Do Rayovac batteries have problems with
leaking?
might be helpful to mention the timeframe.
How many years were they in the flashlight?
What's the expiration date printed on the leaky cells?
