Quick Answer
The best batteries for outdoor survival kits are high-capacity, cold-weather-resistant lithium batteries like lithium-ion or lithium-polymer batteries from well-known manufacturers. These batteries provide reliable power in extreme temperatures and can be used to keep vital devices, such as flashlights, radios, and first aid equipment, functioning.
Choosing the Right Batteries for Outdoor Survival Kits
When selecting batteries for your outdoor survival kit, consider their cold-weather performance, shelf life, and capacity. Lithium-ion (Li-ion) batteries are a popular choice due to their high energy density and low self-discharge rate. They retain up to 80% of their capacity even after being stored for 12 months at 40°F (4°C). Look for Li-ion batteries with a capacity of at least 10,000 mAh (milliampere-hours) to power multiple devices.
Cold-Weather Performance and Shelf Life
When shopping for batteries, look for the following specifications to ensure they will perform well in cold temperatures:
- Operating temperature range: -20°C to 60°C (-4°F to 140°F)
- Storage temperature range: -20°C to 40°C (-4°F to 104°F)
- Shelf life: at least 12 months
- Capacity retention: at least 80% after 12 months
