Title: deltran battery tender jr
Post by rl153 on 09/13/10 at 12:16:00

I was thinking of putting my deltran battery tender junior,connected to the big crank battery on the bike on a timer for the winter for a couple of hours once a week in the garage,I really don't want to leave it plugged in all the time . My question is, while the timer has the current off, and the tender is still connected to the battery ,will there be current somehow drained from the battery? Thanks!

i think you can run battery tenders all the time 24/7

If you use a battery tender your battery want last as long,Use a battery charger once Half way threw the winter and your battery will last a lot longer,Tender burns up the battery.

Isn't that what a float charger is for?

All the battery tenders are designed to be left connected all the time. I have batteries that are over 10 yrs old and still load test almost perfect, and only because it is on a float charger all the time.
Batteries last unbelievable lengths of time if left on a float charger such as the battery tenders.

But if for some reason you don't want to use it as it was designed for, then don't.

To answer your question, I don't know.

From Bill's post above, I don't know if he is senile, or doesn't have the foggiest idea what a float charger is, and is possibly thinking of the old "trickle" chargers which really will burn up a battery, but it is up to you if you want to believe any part of it :-[

Routy what kind of a battery do you have in your S40

Title: Re: deltran battery tender jr

As far as I know, it is the original. But it was weak when I got it a year or more ago, and only serves me well yet because I leave it on a float charger much of the time.

I used the deltran last winter...it worked great. I didn't leave it on all the time, just used the quick connect jumpers they supply with it and would charge it overnight a few times a week....stock battery as far as I know...

I normally charge mine once half way throught the winter,But last year for the fun of it I went 4 months without doing anything it started right up, 06 with the battery that came in it.

Best solution: don't buy a battery tender-save the money and move to So Cal where you can ride all year long-usually in beautiful weather(we also need more tax payers) ;)-Ride safe, far, and often-Luke

Use whatever you want to use, however you want to use it.
You'll never get a concensus about batteries, battery chargers, battery tenders, trickle chargers etc, around here.

Personally, I would pick one, and follow the manufacturer's instructions. ;)

I find the battery charger on the bike works best.

Hey Bill,
I agree w/ that !......providing you ride often enough, and long enough to replace the juice that you took out from starting it.

The problem can come mostly in cold weather,.....
we want to ride, so we fire it up, roar off, and after 20 minutes or so, enough of this BS freezing cold, so we come back and park it,.........
never knowing that we didn't come close to replacing the juice that it took to start it,...especially in cold weather. So, every time we do this, the battery slowly becomes more discharged, w/o us even knowing it till all of a sudden one day it doesn't start. We then in turn think that the battery all of a sudden went bad, when in reality it was just slowly being discharged.
Not a problem ??? Just charge it up and we're ready for another week or 3 of "battery torture" !
Right, ....except the fact still remains that anytime a battery is less than FULL charged, it is slowly sulfating, and will show up in battery longivity.
It has been proven that if a battery stayed fully charged 100% of its life, it could last anything less than forever.....so to speak.

It is for this very reason why float chargers have become so popular, and really do increase battery longivity in such situations.

Just in case anybody is interested ,I called deltran ,and they told me the tender jr. does not have any reverse current when the ac power source is removed ,so I'm going to put the charger on a timer this winter to charge a few hours once a week .

Title: Re: deltran battery tender jr
Post by Routy on 09/16/10 at 17:28:03

Hey, that makes good sense, because that way instead of the charger only running 100% of the time, you have a timer running 100% of the time, plus the charge running part of the time,.... ::)

Somehow,maybee it's my imagination,it seems safer to have the timer running ,rather than the charger all the time.

Title: Re: deltran battery tender jr
Post by Routy on 09/17/10 at 07:05:47

Not always, but most times it is safer to use stuff as it was designed to be used.
Your charger is a 2 stage charger. Once charged, it will drop down to float voltage (13.4 max) and stay there, during which time it will use very little if any water.
Running any multistage charger for short periods of time on a timer, could cause it to spend most.....if not all of its time at higher voltages, possibly causing more water usage, especially in warm weather.
If for some unknown reason I thought I had to run a timer, I'd prefer to run it on a single stage float charger such as the 1 amp from Harbor Freight.

You're probably right,about the battery tender jr..I also got the harbor freight one, but when the ac current is removed from it ,the light stays on,which I think means it is draining the battery.

If you're not socked in on snow or ice, ride it! No timers except what you can stand and great for winter blues. I'm good for 40 miles at 40 degrees. I know that's pitiful, but it's still riding. I have a float charger still new in the box, but I never got around to hooking it up. And I don't ride if there is a chance of ice.

That's what I do - hook my cheapo, 1 amp battery chargers up to a timer.

I do it for all five of my bikes (I don't own a cage). I don't really trust "smart" battery chargers, so I do it this way. My setup uses a digital timer and it cuts all 5 battery chargers on for 40 minutes every night.

Actually, the Savage (being my "daily rider") gets a "smart" charger, but it's still downstream of the timer and therefore is activated for only 40 minutes/day.

Everything is mounted to the ceiling to reduce clutter.

The sheet metal you see up there is to mitigate any possible (but unlikely) fire hazard.

I've tried my float charger ,for a while with and without the timer . Without the timer ,the charger is constantly on and warm which is normal, but bothers me a little . With the timer ,the charger blinks green for 15 minutes when it first goes on ,then turns green . I'm running it for an hour a day . It seems ,it can't really do much harm to run it this way ,and also safer.

You remind me of my long departed mother,.....thought if she left a light on while she was gone it could burn the house down. And I guess she was right, it could ! :o :)
