It is important that all lithium batteries are well cared for to achieve optimum performance. Many batteries now are equipped with a device that will enable a manufacturer to see exactly how the battery has been used. If a battery has not been looked after according to manufacturer’s instructions it may not be covered by their warranty.
The life of the Battery will depend on the quality of the cells used to construct it. A battery with high quality cells, kept well maintained and used correctly according to the manufacturer’s instructions should give good service for more than 3 years, this is a key point when making the purchasing decision due to the high cost of replacements.
