  • Consider a lithium-ion compatible charger if your bike uses a LiFePO₄ battery, as charging requirements differ from traditional lead-acid models.
• Terminal Cleaning and Corrosion Prevention

  Corrosion on battery terminals increases electrical resistance, reducing efficiency and potentially causing starting issues.

  • Inspect terminals monthly for white, green, or blue powdery buildup (indicative of corrosion).
  • Mix one tablespoon of baking soda with 8 oz of water and apply it to the terminals using a brush to neutralize acid residue.
  • Wear nitrile gloves and safety glasses—battery acid and corrosion byproducts can irritate skin and eyes.
  • After cleaning, rinse with clean water and dry thoroughly.
  • Apply a thin layer of petroleum jelly or a commercial anti-corrosion spray to both terminals to inhibit future buildup.
• Checking Electrolyte Levels (Flooded Lead-Acid Batteries Only)

  Note: This does not apply to sealed AGM (Absorbent Glass Mat) or gel batteries, which are maintenance-free.

  • For conventional flooded batteries, check electrolyte levels every 1–2 months, especially in hot climates or after heavy use.
  • Ensure the liquid covers the lead plates inside each cell—exposed plates can sulfide and permanently reduce capacity.
  • Top up with distilled water only. Tap water contains minerals and impurities that can contaminate the electrolyte and accelerate internal degradation.
  • Do not overfill; keep the level just below the bottom of the fill well to allow for expansion during charging.
