I bought a Deltran Batt Tender Jr to hookup to my battery during the cold days that I don't ride. Is this a good battery tender to Use? Also, I have a Brand new full charged Battery that I got about a month ago after I found out that the old battery that was in the bike was 2 yrs old and the bike was sitting idle for about 6 months. This is how I got a new Battery. The bike was hard to start, I would press start switch and 2-3 seconds later it would start. It did that for about a week. Then One morning I went out and the bike would Start, so that's when I go the Deltran Batt tender Jr. hooked it up to battery and left it on the batt until the tender light turned green. Press Start switch same thing 2-3 sec delay then starts up. So, after I got back from work I parked bike and covered it up put Battery tender on it because it was going to be about 3 days before I rode the bike. Well, went out to bike the Batt tender light was green and unhooked it from batt and pressed start switch and the motor turn like it was real cold. Then nothing but a clinking sound like the Battery was dead. So I tried to jump it off and no luck. Took Battery out my son to me to HD shop and the batt was shot. So, I had to buy a brand new Battery. Now having a new fully charged battery if I put the tender on it, the tender shouldn't overcharge it right?

 

The Battery Tender Jr is called a smart charger. It monitors the batteries charge and adjusts the output so the battery is not overcharged. Lots of good information on their site:

Thank You Vernal, I did go to their website and read up on it. I feel a little more confident in the Batt tender on my batt now. I just think the battery that was in there was about to go anyways.

 

Sounds like the previous battery had a bad cell or was just plain worn out.

You will have no problem with the new battery on the Battery Tender Jr. it should maintain your new battery, and as stated it will not overcharge.

 

Thank You nhrider1 i fell better now. I'm going to hook it up to Battery tonight when I get home because it suppose to be in mid to high 30's at night and during day low to mid 50's and rainy down here in Alabama. Next week should be a good week to ride to work.

 

Another possibility with the previous battery is that there was a poor electrical connection, which can eat up power on starting. It would be worth dismantling, cleaning and reassembling your battery cables at both ends, just to be sure.
