This is starting to piss me off. Had her on the charger over the weekend. I park outside(no choice) so she was out in the cold. Rode yesterday no problem. Rode today, stalled the bike because I didn't wait long enough for her to warm up before trying to leave and she went click again. Put her back on the tender for less than 1 minute and she started. Took the long way to work. I hope she starts when I go to leave. Is it okay to bumpstart? Will have to fix up a bypass switch as well.

Well, that would be my question; I hope I'm not showing my age here with a dumb question, but why the heck couldn't you just push-start a bike with a dead battery like we did in Ye Olden Days (and couldn't always afford a new battery every year or so...)???

You can, although at 225kg (495 lbs) it's not easy. Some discussions here:

Thanks Forchetto. Since motorcycle parking is on the second floor of the parking garage and the battery stills primes the fuel pump with no problem I should be good to go if need be.

Just need to remember 2nd gear or higher and pull out the enricher.

I do sometimes wish I lived a little farther from work.

I replaced the battery on my '06 scrambler about a month ago with a Shorai lithium iron (yes, iron, not ion). I guess I can't really say for sure that this is the best solution since I've only had it for a short time, but assuming the claims are true it seems like a no-brainer to me. Twice the price, but twice the lifetime, no tender needed unless you are in the habit of leaving your bike dormant for more than a year (this tender business is for the birds), and super-light. Also - you can get the smaller box size and free up a little space in your battery compartment for...well...whatever you want to do with that extra 20 cubic inches.

Very interesting - thank you!

It is very imperative to charge a new battery properly the FIRST time it's charged. Whatever voltage the battery registers when the initial charge is interrupted the 1st time is the highest it will ever attain no matter how high the voltage of any subsequent charge. If you stop charging, the 1st time, after the battery has only built up to 12.8 volts - it can never get any higher. If done properly and charged to 13.5 or higher, again - the 1st time, you will have the potential through out the battery's life for that voltage. I have bought many new batteries supposedly charged properly only to find when I got home they weren't. Fortunately, the dealer from whom I bought my Thruxton charged mine properly and it holds over 13.5 volts even if the bike sits for weeks.

Fired right up for the ride home yesterday. Put her on the charger and she fired right up again this morning. I guess while the cold lasts I need to pop her on the charger at least a couple of times aweek or every day it isn't raining.

I know 40° isn't really cold but it does have an adverse effect on the battery.

Bluesman, I had no control over the battery in my bike but I know the one in the wife's Bonnie was done correctly since I did it and followed Yuasa's instructions and used the charger they recommended.

I bought the Optimate charger recently,looking forward to trying it out this year after using the Deltran product in the past with good results.
I like the fact the Optimate plugs into the Auxiliary Power Socket with the optional adapter. Very convenient.Gives more comprehensive information on the condition of the battery also.

I bought a shorai lfx18A1-BS12 for my 2012 T100 and so far it's been horrible. After fully charging it and installing it in the bike it wont start the next day when is 0-5c outside all I get is a "click".

I had charged it to 14v before installing and it was reporting 12.7v when it was cold and key off. It fell to 12v with the key on. I turned the high beams on to help warm the battery up and after several minutes it dropped to 11.9v. Later in the day it was roughly 10c out and key on voltage was 12.3, it was able to start then. The yuasa was able to start the bike when the temp was close to 0c, it was slugish but it started. When the bike runs it's charging at 13.8v. Where I have to park I am unable to have a tender hooked up to the bike, this was the main reason I bought the shorai.

I've sent the battery to Shorai for testing. I'm hoping I got a defective unit because if this is how it responds to cold weather I just bought a $200 paperweight.
