Mobike will not go…
Andrew: Battery is flat and won't hold a charge. Bike is only two years old. Shouldn't the battery last longer than that?
Orlando: Depends how the bike is treated. Has the motorcycle been sitting unused?
Andrew: Yeah, well, it did sit for about three months straight while I was traveling.
Orlando: A lead-acid battery sitting will sulfate. That is, sulfur crystals build up on the lead plates, harden, and reduce the battery's ability to hold a charge.
Andrew: Hmm. The bike sits around around a lot. How can I prevent the battery from going flat?
Orlando: Couple of options. The simplest is disconnecting the negative wire from the battery terminal when you leave, which stops the electrical drain. A better option is using a small battery tender attached to a pigtail.
Andrew: Disconnecting the wire makes sense. But a pigtail?
Orlando: A short wire harness that connects permanently to the battery terminals. The other end has a quick-disconnect plug that peeks out from under your seat or side panel so you don't have to remove the battery cover every time.
Andrew: Oh, convenient! So I just leave that harness attached all the time, and then what do I do when I store the bike?
Orlando: Exactly. When you park the bike for a while, just plug the battery tender directly into that quick-disconnect plug. The tender will monitor and automatically maintain the charge without overcharging it, preventing sulfation.

Use it or lose it. A battery can be gone in three months if unused. Could go a dozen years if under constant use.
