L91 Description

Short technical summary and product information.

The Energizer L91 is a primary lithium battery in the AA form factor, utilizing lithium/iron disulfide (Li/FeS2) chemistry. It delivers a nominal voltage of 1.5V and is capable of continuous discharge up to 2.5A and pulse discharge up to 4.0A (2 seconds on, 8 seconds off). The battery has an internal resistance of 120 to 240 milliohms and operates over a wide temperature range of -40°C to 60°C. With a shelf life of 25 years at 21°C, it is well-suited for long-term storage and high-drain applications. The button top termination allows for easy series connection. Typical weight is 15 grams and volume is 8.0 cm³, with dimensions of 14.5mm diameter and 50.5mm height. This battery is designed for devices requiring reliable power in extreme conditions, such as outdoor equipment, medical devices, and security systems.
