Simple Tips To Keep Lithium Batteries Working Well

Here are simple yet effective tips to keep your forklift lithium batteries working well for years:

1. Avoid Full Discharges

Keep charge between 20%–80% for daily use.

Only do a full 100% charge when necessary (e.g., before long storage).

Never drain to 0%—it stresses the battery.

2. Use Partial (“Opportunity”) Charging

Unlike lead-acid, lithium batteries love short, frequent charges.

Plug in during breaks—no need to wait for a full discharge.

3. Store at Mid-Charge (40–60%)

If storing for weeks/months, keep at ~50% charge.

Avoid storing at 100% or 0%—both degrade the battery over time.

4. Keep Batteries Cool (But Not Cold)

Ideal temp: 15°C–25°C (59°F–77°F).

Avoid extreme heat (>45°C / 113°F) or freezing (<0°C / 32°F).

Store in a shaded, ventilated area.

5. Use the Right Charger

Only use a lithium battery charger (lead-acid chargers can damage them).

Fast charging is fine if the battery supports it.

6. Clean & Inspect Regularly

Wipe terminals to prevent corrosion.

Check for swelling, leaks, or damage (rare but serious).

7. Update Firmware (If Applicable)

Some smart lithium batteries get BMS (Battery Management System) updates—keep them current.

8. Avoid Overloading the Forklift

Excess weight strains the battery, reducing lifespan.

9. Rotate Batteries (If You Have Multiple)

If possible, alternate between batteries to even out wear.

10. Follow Manufacturer Guidelines

Each brand (e.g., EnerSys, Green Cubes, Flux Power) may have specific best practices.

By following these simple habits, your lithium forklift battery can last 8+ years with minimal performance loss.
