Lithium Ion Batteries
I'm riding a BMW 650 single and I'm now in Thailand. I have just charged my battery and it's not going to work, it's cooked. This is now going to be my 4th so maybe it's time to think of an alternative to endlessly pouring money down the drain.
In my bike's defense, it's not all her fault. When i was in London I had an attempted theft, they destroyed the ignition barrel and I replaced it with a marine switch. Sadly I left the lights on and killed my first one. I replaced it with a gel battery. That got cooked when some arsehole pulled out the wiring loom to joyride her and cooked the battery! Third one was not a perfect fit but seemed to work. It got low through lack of proper use and I had to fly back to London for 3 weeks, got back and yet another dead battery in deep-discharge.
So I see adverts for Lithium Ion. A third of the weight and more power. Ok, I'm interested even though they're quite expensive. One advert says they're not much good in the cold (not a huge issue in Thailand) but what worries me more is the fact that my laptop battery is cooked in 2 years using the same technology.
Has anyone used these? Are they worth it?

Are you speaking of lithium ion or lithium iron? They are not the same thing.
Shorai is one manufacturer making lithium iron batteries. I bought the bullet and installed one in a DR-650 and one in a DR-Z400.
They are indeed *very* light and compact. Almost surprisingly so but that is in comparison with what we are used to.
I did read about the negative performance in cold weather. I can attest that I was starting the DR-Z well below freezing. Apparently they like to "warm up" -- i.e. run something with a draw for a few minutes (lights, grip heaters) and then fire it up. I was also a little surprised at how much cranking power I could get out if it when the bike was slow to start after sitting for several weeks. I suspect that the previous lead acid battery would have been drained at this point, or at least start to feel this way.
Anyways, I am definitely not trying to make a sales pitch.
That said, neither of these bikes have big adventures planned for them in their near future. *Personally* I don't feel that verdict is out yet. I have been pretty happy with the AGM battery in my KLR and its still works well after several years including a trip lasting several months.
I would love to hear feedback from others.

We just used Shorai batteries on a world record altitude expedition into the Andes. Every morning the temps were -10 c or so. We never had a problem starting the bikes (even at 6200 metres), but then we knew the starting procedure. You need to create some electrical drain on the battery to warm it up.
Put it this way, warming up a shorai battery is as simple as cranking it once or twice or running the headlight for 30 seconds. Warming up a lead acid battery is a case of sleeping with it in your sleeping bag, or sticking it in a hot tub of water for half an hour.

Colebatch.. nice job on the Andes trip! which Shoria battery (LFX 36?) did you take and what bike was ridden?
doing a series of LiFePO4 battery tests. trying to gather much information as possible. especially under cold conditions.

The only reason I mention the cold thing is when I search for an Li battery for my bike I find one on ebay with a warning on the advert that they won't work at lower temperatures. At this point it's not a huge problem. My issue really is that I'm now in Thailand for maybe a year and I'm using the bike infrequently and the batteries are just not lasting. I had an issue a few months ago where she just wouldn't start as the only run she was getting was a mile a day through Bangkok traffic. When she cooled down she fired up fine but two days later I had to fly and I was gone 3 weeks. I came back to a dead bike... obviously really. I just don't want it to happen again, not least because getting parts here is a pain in the arse.
I've never heard of "Lithium iron".

There are a lot of threads on lithium iron on ADVrider. Some with nothing but bullshit, others with good solid info. It's easy to pick it once you do a bit of homework on it. Look for LiFePo4. This is lithium IRON phosphate. Anyone that calls these batts li ion are mistaken as they've now gone down different paths of development.

I put Shorias in a KTM 950, GSA and MTS 12, live at 7000' (apprx 2100M) and have had 95" (about 2.5 m)of snow this winter, and major below freezing temps. I ride all the time and have not had a bit of trouble starting, sitting out on overnight trips. I have never had to pre-start the Shorias and they work perfect, even the GSA sat for 4 months. I have a Shoria charger but haven't used it YET. Now, they were all purchased in Nov 11 so still new. The KTM explodes when started, I barely touch the button, the GSA a couple of turns and the MTS...3! I was initially worried, as who buys all new batteries from a new mfgr. Me? so far so good.
