A simple charging routine with a built-in response
Place charger inside
Install the charger using the included bracket setup and place the battery on the charger inside the unit.
Route the power cord
Run the charger cord through the rear access hole and install the cover plate with supplied hardware. Open lid and install a one inch piece of a 3/16 plastic zip tie.
Charge as normal

Automatic lid closure
If heat builds during a thermal event, the sacrificial tie melts, the lid drops shut and oxygen is limited helping to prevent a larger fire.
Frequently asked questions

Built after a near miss at a family farm shop
Founder story
The realization for the need of something to protect our buildings came from a near miss at our family farm shop. During lunch hour a charger and battery caught fire and began a thermal runaway event. Luckily, our crew caught it and got it out of the building before it spread. Watching that fire is what pushed us to build a better way to reduce the risk around charging rechargeable batteries.

Battery Casket – Lithium Battery Fire Suppression Enclosure
Don't Let a Battery Fire Burn Down Your Building
Lithium-ion battery packs are everywhere — and so is the risk of thermal runaway. When a cordless drill battery or charger overheats and ignites, the results can be catastrophic. The Battery Casket is a heavy-duty metal enclosure engineered to contain exactly that scenario.
Place your cordless drill charger and battery pack inside while charging. If thermal runaway occurs and the battery or charger catches fire, the Battery Casket's lid automatically closes — suppressing the fire before it can spread. It's a simple, passive layer of protection that could save your workshop, garage, or building.
Why the Battery Casket?
- 🔥 Fire suppression by design — the lid closes automatically during a thermal event to contain flames
- 🔩 Heavy-duty metal construction — built to withstand extreme heat
- 🔋 Compatible with cordless drill chargers and battery packs
- 🏗️ Ideal for workshops, job sites, garages, and commercial buildings
- ✅ Passive protection — no power, no sensors, no maintenance required
At $200, the Battery Casket is one of the most cost-effective fire safety investments you can make. One prevented fire pays for it a thousand times over.
