How to maintain the laser level battery?

1. Battery Compatibility & Selection
Always use manufacturer-recommended batteries (e.g., lithium-ion, alkaline, or NiMH) specified in your device manual. Non-compatible batteries may cause voltage instability, reduced runtime, or permanent damage. Lithium-ion batteries (e.g., Klein Tools 93PLL models) are ideal for high-performance devices due to fast USB-C charging (full charge in ~8 hours) and long cycle life. Alkaline batteries suit low-power backup use but require regular checks to avoid leakage.

2. Charging & Usage Best Practices
Initial Charge: Fully charge new batteries before first use to activate their chemical capacity.
Daily Charging: Use only the original charger to prevent overcharging or undercharging. Charge in a stable, dry environment (ideally between -10°C to 40°C) and disconnect once fully charged (monitor indicator lights).
Avoid Deep Discharge: Recharge lithium-ion batteries when they drop below 20% to prevent triggering protection circuits. Extreme temperatures accelerate aging; avoid prolonged exposure to heat or cold.

3. Storage & Long-Term Care
For short-term storage, remove batteries to prevent leakage and store the device in a dry, shaded area (<60% humidity). For long-term storage (>1 month), keep lithium-ion batteries at 50-80% charge to minimize capacity loss. Perform a partial charge-discharge cycle every 3 months to maintain battery health.

4. Safe Replacement & Troubleshooting
Replacement Steps: Power off the device, remove old batteries, clean contacts with alcohol wipes, and install new batteries according to polarity markings (+/-).
Swollen Batteries: Immediately stop use, handle with gloves in a ventilated area, and dispose of via certified recycling channels. Never puncture or dispose of in regular trash.

5. Common Issues & Solutions
Device Failure to Start: Verify correct battery orientation, clean contacts, or replace batteries.
Dim/Flickering Laser: Low battery charge is the primary cause; recharge or replace. Persistent issues may require recalibration.
Reduced Runtime: Cold environments or aging batteries are likely culprits; contact support for diagnostics.
