Battery Buying Guide

Flooded

Flooded lead acid batteries are the most affordable motorcycle battery, but tend to have shorter lifespans than AGM or lithium batteries. They also require additional maintenance.

Since flooded batteries are not completely sealed, they lose water due to evaporation when they are recharged. If you have a flooded battery, you may need to offset this water loss by periodically adding distilled or deionized water. Otherwise, the battery's plates can become corroded, shortening the battery's lifespan.

AGM

AGM (short for Absorbed Glass Mat) batteries are completely sealed. This makes them spill-proof and maintenance free. While flooded batteries lose water due to evaporation, AGM batteries contain a one-way pressure relief valve that prevents gasses from escaping. When an AGM battery is charged, the gasses inside recombine into water via a process called oxygen recombination.

In an AGM battery, the electrolyte is held in stasis in a number of fiberglass plate separators. This gives AGM batteries a number of advantages over flooded batteries, including longer lifespans, faster recharge times, and slower discharge rates. They're also more resistant to vibrations and extreme cold and heat.

AGM batteries have a greater upfront cost than flooded batteries but can end up costing less in the long run, due to their longer lifespans.

Lithium

Our X2Power lithium iron phosphate (LiFePO4) batteries are the safest, lightest, and fastest motorcycle batteries on the market. Due to their superior chemistry, lithium batteries have roughly 4X longer lifespans than most batteries and charge up to 2X faster.

Lithium batteries also have very low self-discharge rates, which means they hold a charge for much longer in storage. They're also about 55% lighter than a lead acid battery.

On the cost side, lithium batteries do cost more upfront, however, they last so long, you typically end up saving money with a lithium battery in the long run.
