How to storage golf cart lithium battery?

Storing a golf cart lithium battery (LiFePO4) properly is crucial for maintaining its lifespan and performance.

1. Charge to the Correct Level Before Storage

For short-term storage (1–3 months):Charge to 50–60% (ideal for lithium batteries).

For long-term storage (3+ months):Charge to 40–50% (prevents stress on cells).

Avoid:Storing at 100% charge (accelerates degradation).

Storing at 0% charge (can cause deep discharge damage).

2. Disconnect the Battery (If Possible)

Turn off the golf cart’s power switch.

If storing for long periods, disconnect the battery terminals to prevent parasitic drain (some carts have small power draws even when off).

3. Store in a Cool, Dry Place

Ideal Temperature: 10–25°C (50–77°F)

Avoid:Extreme heat (>35°C / 95°F) – speeds up degradation.

Freezing temps (<0°C / 32°F) – can damage cells.

Humidity: Keep in a dry area (avoid damp garages or sheds).

4. Check & Recharge Periodically

Every 3–6 months, check the battery voltage:

If voltage drops below manufacturer’s recommended level (usually ~3.0V per cell for LiFePO4), recharge to 50%.

Do not leave fully discharged—this can permanently damage lithium batteries.

5. Avoid Physical & Electrical Risks

Fire Safety: Store away from flammable materials (lithium batteries are generally safer than lead-acid but still need caution).

No Metal Contact: Prevent terminals from touching metal (risk of short-circuiting).

6. Before Reusing the Battery

Recharge to 50% if it was in storage.

Perform a full charge cycle before heavy use.

Check for swelling or damage—replace if unsafe.

BNT Golf Cart Lithium Battery Storage Tips

Storage Charge: 50% SOC (State of Charge).

Special Feature: Self-discharge rate is very low (~2–3% per month), so less frequent check-ups needed.

Winter Storage Guide for Lithium Golf Cart Batteries 

1. Pre-Winter Prep

Clean terminals (remove corrosion with baking soda + water).

Charge to 50% before storage (never 100% or 0%).

2. Indoor vs. Outdoor Storage

Best: Indoor (climate-controlled garage or basement).If Outdoors: Use an insulated battery box to buffer against temp swings.

3. Temperature Extremes

Below Freezing? Most LiFePO4 batteries can’t charge if cells are <0°C (32°F).

Fix: Warm the battery to 5°C (41°F)+ before charging.

Heat Risk: Storage above 30°C (86°F) accelerates degradation.

4. Monthly Check-Up

Voltage Check: Ensure it hasn’t dropped below ~48V (for a 48V pack).

Physical Inspection: Look for swelling or leaks.

5. Spring Reawakening

Recharge to 50% if voltage dropped.

Full balance charge before first use.

Test performance with a short drive before heavy loads.
