RE: BMW Garbage Batteries - 4

This thread looks like the closest thing I'm going to find to answer my question. The trouble is, the answers are all over the place. I'll have owned my 2018 R1200RS for 5 years next month. The bike is just short of 27,000 miles. I still have the original battery and it's always on a trickle charger when the bike is in the garage. I ride pretty close to year round and for the last year I've had the additional winter time load on the electrical system of a heated jacket and gloves. Love those! I'm starting to think about replacing the battery when I do my annual maintenance. I've had car batteries die on me with absolutely no advance warning at all and I'd rather not be stranded on the bike. Thoughts? Seems like 5 years is the longest I'm seeing without replacement. I'm also curious about the post staying battery fault codes were read during annual maintenance. Is that something you'd see when the GS-911 is plugged in or elsewhere?

You say you use a "trickle charger". Did you mean a "battery tender"? There's a difference.

If you want "peace of mind", buy this for $90
https://www.amazon.com/gp/product/B000N5...le?ie=UTF8&th=1
and let it set, uncharged, in your garage until the OEM battery dies. On that day, fill the new battery with acid, charge, and install.

OEM battery 8 years here. 45,000 miles.
Hibernates from November till March.
Lives on an Optimate 4.

AGM batteries should arrive fully charged, ready to fit. The ones I have bought have come in sealed cartons from the factory so presumably left the factory fully charged.

A theory: as the OP hails from Florida and Richard is in California, is the average ambient temperature of the bike's location significant?

Do we have any posters in the southern parts of Europe who experience short battery life?

It is a battery tender, not a trickle charger. I think I'm just going to replace it for the piece of mind. I wouldn't mind if it didn't start one morning. I would mind if I was out and it quit. I had a battery in my Z3 that started when I went to the store, and started when I left the store. I was backing the car into the driveway, got a little sloppy with the clutch and stalled the car. I would not start after that. Nothing when you turned the key. That's the sort of thing I'm hoping to avoid.
