Why Choose Lithium-Ion Over Other Battery Types?
Lithium-ion batteries outperform NiCd and NiMH alternatives with higher energy density, no memory effect, and slower self-discharge rates. They’re lighter, more compact, and environmentally friendlier. The Earthquake 20V 4.0 Ah model leverages these advantages for improved tool performance and user convenience.
How to Maximize the Lifespan of Your Earthquake 20V Battery?
Avoid complete discharges; recharge when the battery reaches 20%. Store in a cool, dry place at 50% charge if unused for extended periods. Clean terminals regularly and use only Earthquake-approved chargers. Extreme temperatures and physical impacts can degrade cells, so handle with care.
For optimal performance, consider implementing a rotation system if you own multiple batteries. This prevents overuse of individual units and allows cells to recover between charges. Seasonal storage requires special attention – remove batteries from tools and store them in climate-controlled environments. Below is a recommended maintenance schedule:
| Maintenance Task | Frequency |
|---|---|
| Terminal cleaning | Monthly |
| Full discharge-recharge cycle | Every 3 months |
| Storage charge adjustment | Before long-term storage |
What Safety Precautions Should Users Follow?
Do not expose to water, fire, or punctures. Use protective storage cases during transport. If the battery overheats, swells, or emits smoke, discontinue use immediately. Follow manufacturer guidelines for disposal and recycling to prevent environmental harm.
When working in humid environments, utilize silicone-based protectants on electrical contacts to prevent corrosion. Never stack heavy objects on stored batteries, as this can compromise internal components. In case of accidental damage, place the battery in a fireproof container and contact local hazardous waste disposal services. First responders recommend using Class D fire extinguishers for lithium-ion battery fires, as water may exacerbate thermal runaway reactions.
