How to Store and Maintain Tomberlin Golf Cart Batteries in Winter

How Does Cold Weather Affect Tomberlin Golf Cart Batteries?

Cold temperatures slow chemical reactions in lead-acid or lithium-ion batteries, reducing capacity by 20-40%. Freezing conditions can cause electrolyte fluid in lead-acid batteries to solidify, risking permanent plate damage. Lithium-ion batteries face reduced ion mobility, leading to voltage drops. Both types experience accelerated sulfation if stored improperly.

Extended cold exposure creates distinct challenges for different battery chemistries. Flooded lead-acid batteries suffer most in sub-32°F environments as their liquid electrolyte becomes slush-like, increasing internal resistance. AGM (Absorbent Glass Mat) batteries handle cold better due to immobilized electrolytes, but still lose 30% capacity at 20°F. Lithium iron phosphate (LiFePO4) batteries maintain 80% efficiency down to -4°F but require insulation below 14°F to prevent cathode stress. All battery types show increased voltage sag during cold starts – a 48V system might temporarily drop to 42V when engaged in freezing conditions.

Which Charging Practices Prevent Battery Damage During Storage?

Use smart chargers with float/trickle modes for lead-acid batteries. Maintain voltage between 13.2-13.4V. For lithium-ion, avoid continuous charging – employ storage mode (3.8V/cell). Charge monthly for lead-acid types. Never store discharged below 50% capacity. Temperature-compensated charging adapts voltage to ambient conditions, preventing over/under-charging.

Advanced charging strategies can extend battery life by 18-22%. For lead-acid systems, implement equalization charges every 60 days during storage – this 15.5V controlled overcharge helps dissolve sulfate crystals. Lithium-ion batteries benefit from periodic wake-up cycles: bring to 80% charge monthly, then discharge to 40% before returning to storage. Always use manufacturer-approved chargers – Tomberlin’s BMS (Battery Management System) may reject third-party units, causing error codes. For multi-battery packs, balance charge individual cells to maintain voltage variance below 0.05V.

“Tomberlin’s Battery Management System requires specific storage protocols. We recommend removing batteries from the chassis in sub-freezing climates. Our testing shows using insulative wraps combined with maintenance charging preserves cycle life by 18% compared to in-cart storage.” – Redway Power Solutions Lead Engineer

FAQ

Q: Can I leave my Tomberlin charger plugged in all winter?

A: Only with maintenance-mode chargers. Continuous charging degrades batteries – use float chargers that cycle on/off based on voltage.

Q: Does storage temperature affect warranty coverage?

A: Yes. Most manufacturers void warranties if stored below -20°F or above 122°F. Document storage conditions.

Q: How long do properly stored batteries last?

A: Lead-acid: 3-5 years. Lithium-ion: 8-10 years. Storage practices account for 40% of lifespan variance.
