≤35 | Key features:
1. Wide variety of shapes and sizes efficiently fitting the devices they power.
2. Much lighter than other energy-equivalent secondary batteries.
3. High open circuit voltage in comparison to aqueous batteries (such as lead acid, nickel-metal hydride and nickel-cadmium).
4. No memory effect.
5. Low self-discharge rate, approximately 5-10% per month.
Main applications: 1. Portable equipment: Laptop, camcorder, PDA, Digital camera, portable DVD etc. 2. Home appliances: Two-way radio, Walkie-talkie, Electric toys, Electric bicycles, Emergency lighting 3. Military equipment: IR telescope 4. Medical devices 5. Power tools |
