As much as you’d like to ride every day, a vintage Honda spends a lot of its life parked — and a parked battery slowly goes flat. Leave it long enough and you’re met with a dead battery and a bike that won’t start, and every time that happens the battery’s life gets shorter. The Motobatt Little Boy keeps it topped off so your bike is always ready to go.
A battery is more like a gas tank for electrons than a generator — it only holds what you put in, and these old Honda charging systems barely keep up on their own. Park the bike for a few weeks and the charge drains away. A maintainer trickles in just enough to hold a full charge, so the battery lasts longer and the bike fires right up. Battery-charger technology has come a long way since these bikes were built; this smart charger is built for that job, not the crude high-output chargers of the era.
Note: This is a maintainer, not a rescue charger — it’s designed to hold a charge or top up a mildly drained battery, not to bring a completely dead one back to life. It works best on a healthy or new battery.
Difficulty: Beginner
The ring-terminal pigtail is meant to stay on the battery so you can connect and disconnect the charger in seconds:
We walk through the whole Motobatt charger-and-battery system in this video:
No — it’s a maintainer, not a rescue charger. It holds a full charge or tops up a mildly drained battery, but it won’t recover one that’s completely flat. Use it on a healthy or new battery to keep it that way.
Yes — it’s designed specifically for AGM batteries (and works with lead-acid too). That matters, because an old-school high-output lead-acid charger can damage a modern AGM battery.
Yes. There’s a push-button mode select with an LED indicator, so the one charger covers both 6-volt and 12-volt vintage Honda systems.
That’s the idea. As a maintainer it’s made to stay connected during storage, and the ring-terminal pigtail stays bolted to the battery so you just plug in and unplug as needed.
