Battery tender Jr?
I have had a battery tender jr for about 7 years. I always plug my bike up when I park it for more than a day. I have not rode my bike in about 2 months. This past week I have noticed my tender doing something I have never seen before. I just happen to getting out of the truck in the garage and notice it go from solid green to start flashing green. I have notice this about 4 times this week. Just went to the garage to get something for the wife and the light was red. I am guessing the battery has gone bad. The battery is just a little over a year old. Has anyone noticed theres doing that?

Don't guess! Start by simply turning the tender off or unplugging it, then starting it up again - a bit like Microsoft! If you have doubts about your battery, use a multimeter to check it's voltage when disconnected. You could also check the charging system on your bike, to make sure it isn't messing you up.

I have the BatteryMinder brand. It has a RED and a GREEN light. When plugged into wall power, the RED light glows, indicating it has power from the wall. Once I plug the connector to the vehicle the GREEN light glows SOLID...until it brings the battery up to charge (typically within about 30 minutes) THEN....it changes to a BLINKING GREEN which idicates it goes into the "maintaining" mode. (perfectly normal). Perhaps your brand does the same. BTW.....as soon as I park in my garage I plug it in.....my batteries typically last 6+ yrs.

If you look on the tender it should say what all of the blinking lights indicate.
One other thing, just because your battery is a year old doesnt mean its good, I would remove battery from your mc, charge accordingly, with a different charger let sit for 24 hours after charging and check voltage.
Subscribing too!
Some testing info.

The battery tender will flash green when the battery reaches 80% of it's full charge. It will show a solid green once it reaches 100% charged. I had a similar experience with a Battery Tender Junior. It would show red and the green flashing lights after it had indicated a fully charged battery. I would unplug the charger and then connect back to the bike. This would correct the function sometimes. I finally went and purchased the 3 amp battery tender. It's all good now. Yes, check your battery but, the charger may have gone bad.

If you can do a voltage test across the battery, I usually go through the pigtail for a quick check. If you can go with out for a couple of weeks send it down to Deltran in Deland, FL. They used to have a ten year warranty on their tenders. Anyways have them check it out and who knows maybe they'll send you a replacement. A fine customer based company. Batteries aren't what they used to be. Check battery connections for any corrosion, clean if necessary.

I stand corrected, the Jr. has a 5 year warranty. The 1.25A tender has the 10 year warranty and the OP did state he was using the Jr. I use both, but been using Deltran products since 2000, Deltran is a good upstanding company that takes care of their customers, I haven't had any problems with them.
