BMW R1200R & R1200S Motorcycle Batteries (2005 - '16)

Why Your BMW R1200R or R1200S Battery Matters

The battery on your R1200 does more than start the engine. It steadies voltage for the ABS, ignition, and fuel injection systems that keep a boxer twin running smoothly, and it's what lets your bike fire up on the first try after sitting in the garage all winter. A weak or aging battery shows up as slow cranking, dim dash lights, or a bike that won't start at all after a cold night.

Common reasons riders replace their R1200 battery:

• The OEM battery is nearing the end of its 3 to 5 year lifespan
• The bike sat unused for weeks or months and the battery won't hold a charge
• Slow or hesitant starts, especially in cold weather
• Upgrading to a lighter lithium battery for track days or weight savings
• A swollen, corroded, or leaking case on the old battery

How to Choose a Replacement Battery for Your BMW R1200

BMW used a few different battery builds across the R1200S and R1200R model years, so it's worth confirming your original battery's part number, voltage, amp-hour (Ah) rating, and terminal layout before you order. Once you know that, the choice mostly comes down to battery chemistry:

• AGM (Absorbed Glass Mat): The standard replacement chemistry for most R1200 models. Sealed, maintenance-free, and budget-friendly, with plenty of cold cranking amps (CCA) for reliable starts. A great fit for everyday riders who want a straightforward, no-fuss replacement.
• Lithium (LiFePO4): A popular upgrade for riders chasing weight savings or longer shelf life. Lithium batteries weigh a fraction of an AGM battery, resist self-discharge during winter storage, and often deliver higher CCA in a smaller case. They typically cost more upfront but can outlast AGM batteries by several seasons.
• Dual-terminal options: Some R1200 builds use batteries with both post and terminal connections (like Motobatt models), which can simplify wiring on certain trims.

We carry both AGM and lithium options for the R1200S and R1200R, including USA-made choices, so you can match your budget, riding style, and how often the bike sees the road.

Frequently Asked Questions

How do I know which battery fits my BMW R1200S or R1200R?

A: BMW used more than one OEM battery across these model years, so the safest approach is to check the part number, voltage, amp-hour rating, and dimensions on your current battery before ordering. If you're not sure what you're looking at, our customer service team can help you match it up.

Can I upgrade from an AGM battery to a lithium (LiFePO4) battery?

A: In most cases, yes. Lithium batteries like the EarthX and NOCO options on this page are built as drop-in replacements for the same case sizes as popular AGM batteries, and they're significantly lighter. Just confirm your bike's charging system is compatible with lithium chemistry, and use a charger rated for LiFePO4 when it's time to top it off.

Do I need to do anything special to install a new motorcycle battery?

A: Most AGM and lithium batteries on this page arrive charged and ready to install. Disconnect the negative cable first, then the positive, remove the old battery, and reverse the process with the new one, connecting positive before negative. Always check torque specs and terminal orientation against your owner's manual.

Why does my BMW's battery keep dying when the bike sits for a while?

A: Lead-acid AGM batteries naturally self-discharge over time, and that process speeds up in cold weather or with a parasitic draw from your bike's electronics. If your R1200 sits for more than a few weeks at a stretch, a lithium battery (which holds its charge far longer) or a maintenance charger/tender can help prevent this.

What's the difference between the Motobatt batteries and the others on this page?

A: Motobatt batteries use a dual-terminal design with both post and screw-terminal connections, which can make wiring easier on certain R1200 trims. They're still AGM batteries at their core, just with a different terminal setup than the standard YTX14-BS style battery.
