I'm contemplating a lithium jump start battery for winter, and just wondered does anyone here have experience of them? I have a lithium battery on my 996, which seems to slowly lose its charge when parked up. I have no other electrics connected, so there is obviously something slowly discharging it. The other day I had to jump start the bike from my car. So of course I went online looking for solutions and more new gadgets! I'd appreciate any insights and experiences of these booster batteries you can buy for just this sort of situation. Or should I just buy a 12V car battery and keep it topped up for this purpose in the garage?
I use a £30 odd quid USB battery pack from amazon. It has a 12v jump port and leads. I recommend it and have in fact done so to a couple of mates who have the same one and have used it on their bikes. It’s this one.
Lidl do them cheap..... What could go wrong? To be fair we've used them on our charity moped run, but only to keep the mobiles / sat Nav's charged, as the bikes were 6V or no battery.
LiOn batteries don't like the cold. Best bet is to keep it on a trickle charger, needs to be LiOn specific though. The small boosters work well enough, but a trickle charger will negate the need to mess around removing fairings etc. and any chance of damaging the battery by boosting it.
To be fair no vehicle battery likes the cold, but Lithium is more susceptible. Below is a flooded lead acid battery. Please note that 80% of the chemical energy is still present when the useable energy has ceased (terminal voltage above 10V). You can only really use the 12.8 to 10.5V bit... hope that makes sense.
What I don’t get is that you are allegedly supposed to be able to plug these boosters into a cars cigarette lighter type plug to start the car. Can’t see why that wouldn’t fry the electrics...
That’s only the case with an always on ciggie adapter that’s wired direct to the battery. Most are via a relay or wired into the vehicle in other ways. I wouldn’t even bother trying tbh
Isn't possible that something is draining you battery? Maybe removing one of the connectors when stored should stop the above. I have lithium batteries on 4 of my bikes, couple of days ago I started up my R1 (not been run since July and SP2 (no started since August). Both started up fine after "waking up" the batteries. Healdight on for 10 sec then let to rest for 10sec.
This "waking the batteries up" will be something new to many. If I miss a thread can someone else jump in a let people know. Just a quick manual drain on the battery and then wait 10 seconds or so. Brake switch works fine on most. I've not got a "Healdight" on any of my lithium powered devices. This will prevent a great deal of angst and unnecessary charging etc. Just leaves the fires to worry about.
