REMARK
|
- Although, Lead Acid battery is lower in cost and safety acceptable; however, with extremely toxic, worse for the environmental concern, short cycle life, heavy in weight, therefore, we don't put it as a group for comparison.
- Nickel Hydride battery has a characteristic of low Power Weight Density, decayed faster under high temperature, worse in memory effect, not suitable for high output usage, neither for personal computer nor 3C products.
- The C-coated Lithium Iron Phosphate Battery has been proven as the most environmental friendly battery. It is the safest and most suitable for high output and long cycle life. Best for all areas where battery is needed.
- LiCoO2 has an unstable characteristic, it is not suitable for the personal hand-carried electronic devices.
