If you’re parking your Surron for the winter, taking a long break from riding, or just not using it for a few months, how you store the battery matters more than you think.
Your Surron battery is the most expensive part of your bike. Treat it wrong during storage and you can permanently reduce its lifespan. Treat it right and it’ll stay strong for years.
Here’s exactly how to do it the right way.
1. Store It at the Right Charge Level (This Is Critical)
Never store your Surron battery:
-
At 100%
-
Completely dead (0–10%)
The ideal storage charge is:
40%–60%
Why?
Lithium-ion batteries degrade fastest when they sit fully charged or fully empty. Storing at mid-level charge reduces internal stress and preserves long-term health.
Pro Tip:
If your battery is at 80–100%, take a short ride to bring it down before storage. If it’s low, charge it up to around 50%.
2. Keep It in a Cool, Dry Place
Temperature matters a lot.
Best storage temperature:
50°F – 70°F (10°C – 21°C)
Avoid:
-
Hot garages (especially in Southern California summers)
-
Freezing temperatures
-
Direct sunlight
-
Damp sheds
Heat is the biggest enemy of battery longevity. High temps speed up chemical degradation inside the cells.
If your garage gets hot, bring the battery inside the house.
3. Remove the Battery from the Bike
For long-term storage (1+ month), remove it from the Surron.
This:
-
Prevents slow phantom drain
-
Reduces moisture exposure
-
Protects electrical components
Store it upright on a stable surface — not on concrete if possible. A wooden shelf or rubber mat is better.
4. Check It Every 1–2 Months
Even when not in use, batteries slowly lose charge.
Every 4–8 weeks:
-
Check the charge level
-
If it drops near 30%, recharge back to about 50%
Don’t let it sit under 20% for long periods.
Set a reminder on your phone so you don’t forget.
5. Avoid These Common Mistakes
Here’s what damages Surron batteries during storage:
❌ Leaving it at 100% for months
❌ Letting it sit completely dead
❌ Storing in extreme heat
❌ Charging in freezing temperatures
❌ Ignoring it for 6+ months without checking
Most battery problems aren’t from riding — they’re from poor storage.
6. Before Riding Again
When you’re ready to ride again:
-
Let the battery reach room temperature (if stored somewhere cool).
-
Charge it fully.
-
Do a short test ride.
-
Monitor for any unusual behavior (rapid drain, overheating, etc.)
If everything feels normal, you’re good to go.
Final Thoughts
Your Surron battery can last years if you take care of it. Long-term storage isn’t complicated — it just requires discipline.
If you remember one thing, remember this:
Store at 50% in a cool place.
That alone will dramatically increase battery lifespan.
Ride smart. Maintain smarter.
