Fixing a Dead CBR250R Battery with a 3000-Yen Charger

My beloved Honda 'CBR250R' saw a drastic reduction in riding opportunities after I got married, had a child, and bought a Freed.

When I tried to ride it to charge the battery after a long time, the key turned on, but the starter switch didn't respond.

It was too late...
The starter switch was completely dead, so I couldn't even push-start it.

So, I bought this motorcycle battery charger.

If this article was helpful, purchasing through the links here would be greatly appreciated.

When I bought it, Yahoo! Shopping was particularly cheap, and including point rewards, I was able to purchase it for effectively around 2000 yen.

This charger is compatible with all general 12V motorcycle lead-acid batteries (MF/sealed type, open type, AGM type, GEL type, etc.).
The battery on my motorcycle is an 'ATX7L-BS', which is a 12V MF (sealed type) lead-acid battery, so it can be used.

Lithium-ion batteries, etc., are not supported.

As a result, I was able to successfully charge it and start the engine, so I'll introduce the actual steps I took.

Even if you don't have an outdoor outlet, you can just remove the battery and charge it indoors, so
it's fine even for those living in apartment buildings!

Here's what arrived.

It includes the charger unit, vehicle cable, alligator clips, and instruction manual.

I'll also include photos of the instruction manual.

You choose either the vehicle cable or the alligator clips to connect to the charger unit on the outlet side.

It seems that if you charge the battery without removing it from the vehicle, you use the vehicle cable.
If you remove it to charge, you use the alligator clips.

This time, I'll be charging it without removing it from the vehicle, so I'll use the vehicle cable.

Remove the seat of the CBR with the dead battery.

Connect the charger's vehicle cable here.
When connecting, always connect the positive terminal first.

When I connected the other end to the outlet, the yellow charging light illuminated, indicating it was charging!

The instruction manual stated that charging is not possible if the battery voltage is too low (completely empty), so it was good that it wasn't that bad.

And about 4 hours later.

The green light was on.

The 'on' light means 'partially charged, currently full charging,' so looking back, I unplugged it before it was fully charged...

When disconnecting the charger, always disconnect the negative terminal first.

When I turned the key on, the meter spun vigorously, and when I pressed the starter switch, the engine started with a roar! Yay!

That's how I dealt with a dead motorcycle battery by charging it with a 3000-yen charger.

Since it's inexpensive, it's reassuring to have one. (Though I'll probably ride even less now... *sigh*)
