$1800 great...cant wait till the car is out of warranty!

50% weight saving over AGM?

Yeah but the lithium battery is only 69Ah

If i'm not mistaken most E92 M3's came with an 80Ah or 9Ah battery, which is much higher capacity.

I was considering picking up the Royal PowerBurst JS7500 Jump Starter:

27,750mWh jump starter provides up to 400-amp peak power output to start your vehicle in all kinds of weather

I cannot tell if this would work in the F80. Any advice on whether this would be safe and work?

Thanks!

Not speaking from experience with this unit, but generally we can jump start (owner manual) our cars with another vehicles battery operating at 12V, so in theory that should be fine. Charging LIfePo4 batteries requires a special charger. That looks like a cute small unit, though check the very short jumper cables, it would be hard to do the recommended jump-start in the engine bay as the recommended ground point is like few feet from the positive terminal.

Jump starting at the battery is not recommended by BMW, see attached docs.

Which charger is recommended?

Deltran Battery Tender has two chargers that will work on the F80/83 Lithium battery. The smaller one is 800mAh (PN: 022-0199-DL-WH) while the larger one is a full 4A (PN: 022-0209-DL-WH). You can select the battery type so in my opinion this is a superior charger to the CTEK (56-926) charger.

When I bought my car in 2014, I contacted Deltran about getting a battery "tender" from them since I had used them in the past and was pretty happy with their products. I never heard back from them about my inquiry, so I purchased the CTEK unit and have been very happy with it.

Just my $0.02

Here is the email confirmation from a Deltran representative that two of their chargers will work with the M3/M4:

i just had my car boosted with a fully charged booster pack, car started fine, but the battery light is on now and saying "replace battery"

brought it to the dealer and said $2090(Canadian) for a new battery. lack of charge over winter storage was the reason, and not covered under warranty. so i highly recommend buying a lithium ion battery charger(14v) and not one that plugs into the cigarette lighter(as per manual)

funny because when i called the dealer in the summer, i asked about storage and i was told, for a few months i wouldn't worry about it, i should of got that in writing!

Dang, $2k for batt replacement

Wonder if you don't track your car just switch to regular AGM batt ($200), reprogram the computer by indy shop ($150).

I've been reading LiFePO4 need constant-current to go to 80% then constant-voltage charger. So for winter storage if you start with good batt (assuming around 80% capacity to begin with), any cheap charger as long it's not over 14V should be just fine.

I was talking to the service manager and he said the shop foreman said the problem may go away. And when he scanned it, the charging system was working and the battery seems to be good. But I noticed on my gauge cluster that the little bars for efficient driving are lighting up anymore. Which doesn't bother me. So maybe soon an alternative battery will be available.

I purchased my 2015 SO M4 from a dealer 2 weeks ago.

My M4 sat in their lot for over 3 months without battery not being hooked up to a battery tender or being recharged on a regular basis (BMW states charge monthly)

When I bought my car two weeks ago "Replace Battery ASAP" fault message came up.

Selling dealer admitted they failed to charge the battery properly so they will have to replace my battery. I drove the car home (230 miles) without battery dying on me.

I tried to charge it at home but it will no longer take a full charge and must be replaced.

Battery cost: $1,800.00. My battery is getting replaced by my local dealer tomorrow. They will charge the replacement cost to the selling dealer.

I use this for charging all types of battery and it works great. Works with Li-Ion battery too like ours.

For those that have long winters - I highly recommend you keep your battery hooked up to a battery tender as if BMW determines the battery was not charged / maintained properly they may deny warranty claim.

Thought I'd share.

Got myself a Noco G7200 today

Ok so I haven't used the car since January and didn't get a chance to hook it up to a charger either.

Should I hook it up first to a charger and let it run overnight before trying to start the car?

AFAIK you will not hurt the car - worst is that it will not turn over, then you hook up a charger.

Wondering if there's less of a chance in getting low battery sign and then having to replace it like member "whattheheck" experienced if I charge it overnight first.

If you are going to use the CTEK Lithium US charger, and it doesn't appear to charge, use this procedure from their manual to ensure a complete charging cycle:

"Some Lithium-ion batteries have an on-board UVP (under voltage protection) that disconnects the battery to avoid it becoming too deeply discharged. This prohibits the CTEK charger from detecting that there’s a battery connected. To bypass this, the battery charger needs to open the UVP.

By pressing the RESET-button for 10 seconds, the charger opens the UVP. During this process, the charging STEP 7 is lit. Once the UVP has been opened and the battery is ready to be charged, the charger automatically starts the charging cycle."

Did you ever get the battery to charge with the CTEK?
