| **The FLA** is the oldest of the three technologies and is still a popular choice in automotive applications. It is typically the least expensive of the three. The internal charge plates are 'flooded' with liquid battery acid (thru filler caps), thus it's name. These batteries have vents with a tube routed towards the ground for electrolyte expansion, but that also allows evaporation requiring periodic checks & refills. | **The FLA** is the oldest of the three technologies and is still a popular choice in automotive applications.

| - | **The AGM** technology is similar in design, but instead of liquid acid sloshing around inside the battery (and sometimes spilling out), it uses a mat between the plates to absorb the acid. This stabilizes the liquid and keeps it in better contact with the plates, thus creating a more even charge surface. This also means the battery is sealed at the factory and does not require addition of electrolyte later. | + | **The AGM** technology is similar in design, but instead of liquid acid sloshing around inside the battery (and sometimes spilling out), it uses a mat between the plates to absorb the acid.

| - | **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.((https://phys.org/news/2013-04-memory-effect-lithium-ion-batteries.html)) | ||

| 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.
