Using an infrared thermometer I took a reading and the GL18 and VStrom engine casing temperatures in my enclosed carport are 38.8 degrees Fahrenheit.

I will assume the temperature of the rest of each bike is at or near that same reading.

Is that too cold to hook up a battery tender to the motorcycles?

In my opinion you should have a tender hooked up anytime you aren't using them. I've been a lot longer life out of my batteries since I started doing this, I even have a tender on my lawn tractor all year long.

I used to keep a tender on my old 1200 yrs ago, but when I bought my 03 Wing, I never used a tender and got 12 yrs out of the battery.  And that's stored in an unheated garage here in Mi.    Pretty unbelievable I thought, so I now use a tender during the winter on the new battery.    I still start it about once a month and run it at a fast idle for 20-30 min.   My old Wheel Horse mower has only had 2 batteries since 1990---must be lucky I guess.

Thanks for the feedback. My main concern was putting a tender on a battery that was too cold to start the charging process.

Both of my bikes have newer glass-mat batteries in them. The VStrom came with one from the factory, and the GL1800 battery is one I installed at the PO's place before I rode off for the 36 mile ride to my home. I expect to get 5 to 6 years out of both batteries.

I know what the tender manuals say about "safe to leave connected all the time" but I once cooked all of the liquid out of a BMW battery following that advice. So now I put them on once a month to bring the batteries up to max charge and then disconnect the tenders at the plugs.

my Dad passed away in 97 and his 77 Chev pickup still had the factory battery in it. he always kept a small battery charge on it whenever he wasn't using it. but within a week of burying him the battery died too ??????

Depends on what kind of charger, the old trickle chargers never shut off, regular chargers are supposed to, battery tenders are set up to charge then go on float to maintain a charge, which really isn't full charge when you go to start something, it depends on where they are in the float cycle.

Thanks again to all for the feedback. The way I worked out the ritual to keep them charged is a two-pronged strategy.

1. I put them on the tender at least once a month and bring to full charge.

2. I put them on it about 24 hours before I head out for a ride.

The GL has an alternator, but the VStrom is on a stator. So my goal is to not overwork either by heading out on a ride with the battery barely at cranking levels.

....speaking of tenders....

On another post on the Exiles it's been determined my 1 year old NAPA battery is toast. I replaced it (and changed the oil) today. Actually the new battery isn't in yet as it is still charging. It's on hour 5. The flashing green light indicates its 80% or better charged. My tender is a Deltran Battery Tender Plus (below) It's a 1.25A tender. Could this be my problem? I'm looking around and there are a number of them now. How about a 3 amp? Seems to me that would just charge it faster when I want more of a maintainer.

Or, how about this? Maybe it's a waste of time to hook one up?

Thoughts??

I have 4 battery maintainers at my house -

1 on each bike's battery all winter long (1 on bike 1 in basement total-2)
1 on the lawn mowers battery (in basement all winter)
And one Battery Tender Jr. which has been hooked on Ryan's GL1800 - now in his garage -

I use the Sears Diehard version of maintainer - Made by Schumacher (Germany)

They are all 2.0 Amp maintainers - so far -- no problems except when my stator went out on my GS850 while on a ride to southern Indiana...
But that wasn;t the battery fault

Greg, by whatever name they are called, I think any of the newer battery tenders with a microchip brain in it will suffice.

The problem I noted on the other thread was with an older unit that did not have a float, or maintenance mode.

At the moment, both of my bikes are due for a long day ride. The bikes need the exercise, and their owner needs the mental health benefits.  prd
