A long time ago I wrote about the importance of checking your batteries. I had just lost a couple of flashlights and had some corroded terminals on some other devices, so I felt compelled to write about it. Since then, I have done a decent job of regularly checking the batteries in my various devices. However, sometimes I forget to take the summer heat of Arizona into account though. A few weeks ago, I was reminded how important it is to take seasonal temperatures into account.

A couple of years ago I purchased some Maglite XL200 LED Flashlights to go into some of my kits. One of these was destined for the car kit because I wanted a bright yet compact flashlight that could be used in multiple signaling modes. It worked well for me but for most of the summer, I forgot to check it’s batteries. What you would expect to happen next…happened. I had yet another ruined flashlight on my hands despite my best efforts to clean it up. Now it’s back to square one for my automotive emergency flashlight.

However, I do have a plan that should help address this problem in the future. I recently purchased several additional Powerex rechargeable batteries to add to my inventory, which means I have a few that I can spare for a new flashlight. The Powerex batteries retain more of their charge for a longer period of time, so I can leave them in my replacement flashlight without worrying about them being dead when I need them. Plus, I will pack some extra ones in the storage box in my trunk in case I need them. This should address my (recurring) problem with leaking batteries.

None of us is perfect, that is for sure. One takeaway from this is to account for mistakes and use more resilient equipment (in this case rechargeable batteries) as a guard against human error. Let’s hope I heed my own advice more often in the months ahead.
