We got a cold snap the last couple of days. Got down to the low 50's. Not bad for us. I went out to start the V-strom , which had been firing up really well. The battery was nor wanting to do anything . Voltage looked ok. Swapped out for a good spare , and it fired right up. According to my maint log, the battery was about 30 months old.
Point is the cold weather is a killer. Can have good voltage but not the aps to crank over the bike. Most likely will happen when you are in a hurry.
 
I have 2 or 3 of the little "wall wart" battery maintainers, but recently found these at Advanced Discount Auto: Part No. SEM-1562A
$28 and does a much better job than anything else I've come across yet.
 
Wall mart has the Schumacher SEM-1562A for $17.00
 
For 2 winters before the last one I frequently had starting issues. Had a tender as well but once in a while I'd either forget to connect it or the plug wouldn't be fully in the wall (why do they make those things so big and heavy? But I digress) or it simply didn't put enough charge in the battery. At that time my regular daily ride was about 20km - 10 each way. The problem was when the temp dropped below 1 or 2 degrees C. This winter I've been riding about 40km a day and didn't need to connect to the tender once. Same battery, same garaging; only difference is the distance I was riding each day. I still have the handy pigtail connector on the bike so I can plug-in in an instant if i feel the need ie. I'm parked in the open overnite, but the key seems to be miles and regular ones at that.
 
The Battery tender is the life support system for my 2005,one or two weeks off the tender and she doesn't start.
 
Thanks for the tip. WalMart wins again, hell it's all out of the same door in China.
 
I noticed the same thing. Flat battery didn't charge properly after a 30km ride, but did after a 90km ride. Having fixed the problem and now the weather's warming up, my battery tender just turned up off ebay.
