Product Description
This 2-pack offers the premium Delipow 9V 800mAh lithium-ion rechargeable battery. Engineered for long-lasting, reliable performance, this battery delivers an impressive 1200 recharge cycles, meaning one single battery can replace up to 1200 single-use dry cells over its lifetime. It features ultra-low self-discharge technology, retaining up to 70% of its charge even after 5 years of storage. As a lithium-ion cell, it offers zero memory effect and supports approximately 6-hour fast charging. (Note: The actual operating voltage of this Li-ion battery is approximately 8.4V, which is the normal standard for 9V Li-ion batteries and is perfectly compatible with all standard 9V devices. Due to the material properties of lithium-ion technology, the weight is significantly lighter than traditional alkaline batteries, which is a normal characteristic.) With a standard 9V rectangular design and snap terminals, this 2-pack provides reliable, eco-friendly power for multimeters, microphones, guitar pedals, toys, and smoke detectors.
