The energizer ultimate lithium aa battery l91 is a durable AA battery with low-temperature resistance and leak-proof capabilities. The Energizer L91, also known as FR6/FR14505, has an impressive shelf life of up to 25 years and holds the Guinness World Record for the longest-lasting AA battery. It offers complete leak protection and stable discharge performance in extreme temperatures ranging from -40°C to 60°C. This battery also features low-temperature discharge performance that alkaline and rechargeable batteries cannot achieve. Additionally, the battery is designed without electrolytes, fundamentally solving the issue of leakage. Furthermore, it is a true explosion-proof battery.
· Stable discharge and long storage life
· Explosion-proof battery to ensure leak-proof (based on standard use) safety performance
· The weight is 1/3 lighter than the general alkaline battery, especially suitable for heavy load occasions
