HARLEY LITHIUM BATTERIES QUICK GUIDE
Here at Two Tyres we recommend these lightweight lithium Harley Davidson batteries, which weigh just 20% of your Harley’s standard lead-acid battery. For this 66000174 / LTM21L fitment, this results in a saving of a massive 5.3kg compared to stock. All of our JMT batteries come with a 24-month warranty and they are a straight swap for your existing battery.
Unlike some motorcycle battery brands, these batteries are not made in the Far East. They are manufactured in Germany and subject to rigorous testing and strict quality control. They are the OE fitment for some motorcycle manufacturers, including KTM.
Lithium motorcycle batteries have just 10% of the self-discharge rate of a lead-acid battery, meaning you can leave it for months and the battery won’t die. Every lithium battery we sell comes with a built-in battery condition indicator. With a single button press you can check the charge level of the battery.
Our lithium-ion motorbike batteries use iron phosphate (LiFePO4) as the cathode material and use the lithium-polymer process in their manufacture. This means that they will not catch fire or explode in normal operation, which can happen with the cheap, low-quality lithium batteries which are less stable.
They have a higher cranking ability than a lead-acid battery, which is useful when it comes to cranking over large Harley v-twin engines.
