How do I choose the right battery disconnect for my motorcycle?

Typically, you should disconnect the battery after three months of non-use or longer if you know that you won’t be riding for a while.

When it’s time to reconnect the battery, simply turn on your motorcycle and make sure it starts up properly. If the engine doesn’t start, your battery may be dead and will need to be charged or replaced. Regularly disconnecting and reconnecting your motorcycle battery can help ensure that it stays in good working order and extends its lifespan.

Can I use a battery disconnect for storage?
