On a -12°C night on the B-27 jack-up, our AED kept failing its self-test after a couple “late-night shifts”; we solved it by stashing it in an insulated Pelican case with two chemical hand warmers taped inside and swapping them every 12 hours. It’s cheap and kept the battery and pads within spec, but watch for condensation when you bring it back into the warm and crack the case to vent.

We kept our AED from failing self-tests during “late-night shifts” by mounting the case in a small locker with a 5W silicone heater pad controlled by a snap-disc at 10°C and fed from the UPS, which holds it around 8–12°C without cooking the battery. Small caveat: only do this in a non-classified space and confirm your model’s low-temp spec first (e.g., https://www.zoll.com/medical-products/aeds/aed-plus lists 0°C minimum operating).

Quick tip from our last hitch: we kept the AED reliable by rotating in a warm spare battery and pads from the med locker every week, like swapping warm gloves, building on @alice_m82’s heated-mount idea. Small caveat — if you move it from warm to the cold deck, keep it sealed with a desiccant pack for a few minutes to prevent condensation before opening. Also check the manual for the exact ‘standby temp’ — some models are fussier than others.
