| **The LIon** design similarly uses plates, but these plates are highly refined compounds with a similarly refined lithium ion electrolyte material which is not a liquid. This refinement accounts for their capabilities being differernt from the lead-acid batteries and also accounts for their higher costs (which will likely be reduced with increased usage). LIon batteries are virtually maintenance-free. | **The LIon** design similarly uses plates, but these plates are highly refined compounds with a similarly refined lithium ion electrolyte material which is not a liquid.

| - | **The LFP** design is a refinement of the LIon. It has a more constant discharge voltage and a better safety record. However, the LFP design may require cell balancing & may exhibit a 'memory effect' when partially discharging and recharging. Special charging processes (specific chargers for LFP batteries) may be required to resolve these issues. | + | **The LFP** design is a refinement of the LIon.

| These variations must be weighed in light of the environment and usage for a particular application. It’s nonsensical to talk battery life without a valid reference to the environment of the usage - meaning the quality of the charging system plus the way the battery is used. In some sense, this is like the debates of 'best oil' or 'best tire' or even 'best bike'. | These variations must be weighed in light of the environment and usage for a particular application.
