And that's the thing, if your charging system on the bike is working correctly for everything else you run plus you ride for enough time there is no reason the battery isn't more or less fully charged at the end of a ride.

You and I have had similar experiences with them.

I am going to proactively replace my 6 year old X2 with either a XS30L Lithium, or an XS AGM. I am not sure that I will have the bike for 6 more years, so there is that consideration. Currently debating on trading it for a new CVO Limited, OR keeping it and looking for a Dyna.

Not the most relevant deliberation for a battery purchase, but that XS Lithium is $600

My stock HD AGM battery came with the bike almost 9 years old still going strong. I'm using it in my John Deere riding mower no battery tender it never hesitate to fire it right up.

My stock AGM gave up the ghost in the 1st year

One problem with all rechargeable batteries is not keeping them at the right state of charge. For an AGM battery it should be kept fully charged. After starting the bike which takes the most out of it the ride needs to be long enough to recharge it or it needs putting on a charger when you get home to ensure it stays fully charged, IMO.

One of the things I don't understand stand about going to a lithium battery.
If you need a different battery charger/tender for lithium than you do an AGM, why don't you need to change your motorcycles voltage regulator to match the needs of a lithium battery?

Most dedicated Pb chargers do a desulfate stage that would damage a lithium battery.

The output from a charger for AGM could be 14.8 volts which a little higher than required for LiFePO4 batteries.

Most peoples low cost voltmeters possibly can't even see some of theses small differences but just a couple of 1/10ths of a volt can be damaging to lithium cells.

When the weather is really cold reducing the charge volte by just 0.1 volts per cell will prevent damage.

I'm not against lithium batteries. I have 4 12v Lifepo4 100 amp batteries at my cabin, charged by solar or generator depending on the weather and they're light years ahead of deep cell AGM batteries.

But they need different chargers for voltage and amps and that take temperature into consideration. The batteries can be damaged if charged when it's below freezing.

I keep the batteries in a 20' conex box on steel shelves away from flammables just in case.

Just curious, if somehow you run a lithium completely dead , do you not need to put a small charge into it before jump starting it ? And that small charge needs to come from a battery charger/maintainer designed for lithium?

I'm not knocking them ... but things happen , and usually not to home
