Alright, so the other day I was working on my bike, and you know how it goes, the battery was just about dead. So, I decided it was time to hook up the Battery Tender Junior, the lithium version. Let me tell you, it’s a lifesaver for keeping the bike ready to go.

First things first, I gathered all my stuff. I made sure I had the Battery Tender Junior, the right connectors, and of course, my motorcycle. My bike was parked in the garage, which is pretty well-ventilated, so that was a good start. I also made sure the motorcycle was turned off. Safety first, you know?
Next, I opened up the seat where the battery is located on my bike. I double-checked that I had the lithium version of the Battery Tender Junior because you can’t use the regular one on lithium batteries. It’s important to get that right, or you could mess up your battery.
Once I was sure, I took the connector and attached the red clamp to the positive terminal of the battery and the black clamp to the negative terminal. It’s pretty straightforward, but you gotta make sure the clamps are secure and making good contact.
After that, I plugged the Battery Tender into the wall socket. The little lights on the tender started blinking, which means it’s doing its thing. It checks the battery’s charge level and starts charging it up. I kept an eye on it for a while to make sure everything was working as it should. And then I saw the light turn green after a time, and I knew the battery was fully charged and ready to go.
The cool thing about this Battery Tender Junior is that it doesn’t just charge the battery and stop. It switches to a “float” mode, which means it keeps the battery topped off without overcharging it. That way, the battery stays in good shape and lasts longer. And the most important is this model is designed for Lithium batteries, I need to emphasize this because I saw it mentioned that you need to use a new type of voltage regulator with older bikes.
Here are the steps I followed:
- Checked the Battery Tender Junior package to make sure I had all the parts and read the instruction manual.
- Turned off my motorcycle and made sure it was in a well-ventilated area.
- Located the battery and ensured I had the correct Battery Tender Junior for lithium batteries.
- Connected the red clamp to the positive terminal and the black clamp to the negative terminal.
- Plugged in the Battery Tender and monitored the charging process.
- Confirmed it switched to float mode to maintain the charge without overcharging.
So yeah, that’s how I used the Battery Tender Junior on my motorcycle’s lithium battery. It’s a pretty simple process, and it really helps keep the battery in top condition. If you’ve got a bike, especially one with a lithium battery, I’d definitely recommend getting one of these. It’s a small investment that can save you a lot of hassle and money in the long run.
And about the older bikes with generators and/or external voltage regulators, I guess I was lucky, mine is new enough to be fine. But make sure to check your bike’s specs, it’s important to use the right type of voltage regulator to avoid damaging the battery. Better safe than sorry!
Oh, one more thing. I heard from a friend that if you have an AGM, lead-acid, GEL, or flooded battery, you can also use this Battery Tender Jr 800 Selectable. Pretty versatile, huh? Always good to know your options. Well, that’s all from me today. Ride safe, everyone!
