    Lithium Battery on trickle charge??

    Hi, my S1000R has the lithium battery fitted. My question is, is it safe to leave the bike on trickle charge while not in use. This could be for weeks at a time. Thereís a lot of horror stories online about these lithium batteries exploding when on charge (mostly E bikes and E Scooters ) . Am I been paranoid or should I just put it on charge and forget about it?
    Thanks for any replies

    Hi, since I have the S1000R 2021 with lithium battery, I only use Optimate chargers and I have no problems, I connect in mid-December and disconnect in mid-March. This is the model I have:
    Optimate Battery Charger: Optimate Lithium 12V/5A ‎TM291, the lithium ones go down very slowly, they are not like the acid or gel ones.... so they are not affected for two weeks

    Mine too is the Optimate charger, the one specific for lithium batteryís . Iím sure they are designed to be plugged in and forgot about otherwise whatís the point in having a battery charger. I know you canít use a normal battery charger on a lithium battery and vice versa I imagine. I wonder if these e bike and e scooter fires are due to the wrong charger been usedÖÖ..

    if its a good quality charger and defined suitable for Lithium batteries then itll be fine.

    If you really worry then set a phone reminder and only charge every 1/2 weeks, but keep an eye on that voltage drop.
    If you dont mind resetting your clock / effort to lift seat and unplug then maybe even disconnect it fully?

    Depending on the battery type , there are different discharge / cycle rules.  For Li deep or full discharge is really bad and will lead to reduced life or replacement.
    My bike 2017 is still on an old type battery.
    It depends on the current draw of your bike how much this will happen (should be negligible but often its not)

    I have been using the lithium battery maintainer since December 2021 and use it for 4-5 continuous months. And so far never any problems, the Optimates are the best but they cost... And above all once charged, it only does maintenance, precisely because the lithium ones have much less loss than the standard ones

    Iíve got the connector bit connected direct to the battery and poking into the space under the passenger seat so no major problem charging it up. You guys have put my mind at ease so Iíll just plug it in and forget about it. Like I said I use a dedicated lithium battery charger and is Optimate which Iím assuming is a quality brand  I also have a Ctek battery charger that does lithium and lead acid batteries that I use on my car. It does have a button that you have to press to change the battery type though. Thanks for all your replies

    Sorry to revive an old thread, but isn't half the point of Li batteries that they don't lose charge in any practical way?
    Sure, I got a lithium battery because it's so light and "I really notice how much more flickable the bike is" or some such coffee shop flex, but the REAL reason is because I could leave it unattended all winter and it's still got all the cranking amps I need when I dust it off in the spring...
    I had a Li electric outboard on my sailboat and I left it for almost two years and it was still at 75% charge!

    Yeah they last much much longer than normal batteries but I read somewhere that if you leave the security alarm on the battery will be flat in 2 weeks. When my bike is on charge the alarm is also on. No issues so far
