 The battery is used to store power to operate the lights, electronics, starter circuit & ignition system of the motorcycle when the engine is not running. Once the engine is started, the task of supplying power for these purposes is taken over by the charging system, while also recharging the battery. In this way, the battery is ready for the next situation where power is required without the engine running.

-**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 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. It is typically the least expensive of the three.

These batteries have vents with a tube routed towards the ground for electrolyte expansion, but that also allows evaporation requiring periodic checks & refills.
 **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 wet-cell FLA is slowly being phased out with a greater embrace of the AGM or LIon versions. So, in a generalized way, here are the differences between the newer LIon batteries and the less-new AGM batteries:

 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'.
-Factors that need to be taken into account when choosing a battery are: starter motor CCA requirements; charging system capability; average ambient temperature when you ride; temps when bike is stored; number of starts (as in how often do you ride, how often do you stop when you ride, etc.); added accessories that require power when engine is not running; other environmental and usage factors.

 Shorai Batteries require a charging system output of 13.1 Volts or higher at idle, and must not exceed 15.2 volts at maximum output.
+From the [[https://shoraipower.com/faq|Shorai website]]:
+| **What about Water & Corrosion** - Avoid high pressure power washing around the battery case, or constant exposure to water. If the battery may be occasionally submerged, we highly suggest application of sealant to fill the horizontal seam between top and bottom of the battery case, and that the 5-pin port be fully packed with dielectric grease. (dielectric grease is a good idea in any case to insure no pin corrosion). Also, heavy grease should be liberally applied to terminals for wet environments. |
+| **What about Cold Weather Starting** - Down to about 20 degrees Fahrenheit (-7C) most users find that they can start normally on first crank. If your headlight comes on at key-ON, it is good for the batteries to flow some current before cranking in cold weather. The suggested headlight-on time before cranking depends on the temperature. If starting at 40F/5C, 30 seconds will help wake the battery and increase cranking performance. If at 0F/-17C, leave the lights on for 4~5 minutes before cranking. The result will be a better first crank, and longer battery life.  If the engine fails to start on first crank, that first crank has warmed the battery, and the second attempt will be much stronger. Other accessories that can be turned on before cranking can also be used for this purpose, such as heated gear, radio, etc...  Insuring that the battery is fully charged after storage also improves first-start performance in cold weather. |

+===== LED Lighting =====
+LEDs are not only highly shock resistant but they have a very long lifetime and can be made quite bright (and in many different colors). \\
+Using them for turn signals: \\
+Selecting and mounting the LED turn signals can be fairly easy with many aftermarket options. \\
+However, they cannot simply be straight wired in as the OEM bulbs are. \\
+The recommendation is to use a ‘load balancer’. \\
+Here is how a typical turn signal and flasher circuit works: \\
+If all you do first is replace the bulbs with LED lights, all is normal except the lights don’t blink when you push the turn signal switch. \\
+The root cause is that standard bulbs (app around 20-30 watts and 12-14 volts) draw a couple of amps. \\
+Normal electromechanical flashers need an amp or two to flash on and off. \\
+But LEDs draw only a few milliamps, which is not enough to activate the flashers. Hence the edict to use ‘load balancers’. \\
+A load balancer is nothing but a dummy load (or more simply called a resistor). \\
+By installing a resistor in parallel with your light, the resistor acts as a dummy load drawing the amps you need in order to make the flasher work. \\
