As a leading global battery solutions provider, Shenzhen Bak Technology Co., Ltd. understands that a high-performance battery is not only manufactured but also maintained. Whether powering electric vehicles, energy storage systems, or industrial equipment, proper maintenance habits can significantly extend battery life, ensure safety, and preserve optimal performance. Today, we are sharing a set of universal, professional-grade battery maintenance tips to help our global customers maximize their return on investment.
Improper use and neglected maintenance lead to accelerated capacity degradation and increased internal resistance, which not only affects device range and power but can also pose safety risks. A scientific maintenance strategy can effectively slow the aging process, ensuring stable and efficient operation throughout the battery's entire lifecycle.
Based on years of industry experience, we have distilled the following core maintenance recommendations:
1. Temperature Management: Avoid Extreme Heat and Cold
-
Optimal Range: Try to operate and store batteries in a moderate environment of 20°C - 25°C.
-
Avoid Heat: Prevent prolonged exposure to high temperatures (e.g., inside a car under the summer sun) or running high-power applications while charging. High heat is the number one enemy of battery longevity.
-
Beware of Cold: Battery activity decreases in low temperatures, causing temporary performance drops. Avoid high-current charging below 0°C.
2. Charging Habits: Partial Rather Than Full Cycles
-
Ideal Charge Level: Avoid fully draining the battery (0%) or charging to 100% every time. Maintaining a charge level between 20% - 80% or 90% is best practice, significantly reducing stress on the battery's internal chemistry.
-
Periodic Full Calibration: For devices with fuel gauges, a monthly full charge-discharge cycle (charge to 100%, then use it down below 20%) is recommended to help the BMS (Battery Management System) calibrate its readings for accuracy.
3. Long-Term Storage: It's Not Just "Set"
-
Storage Charge Level: If a battery needs to be stored long-term, charge it to 40% - 60%. Storing a battery at full charge or completely empty can cause irreversible damage.
-
Environment: Store batteries in a cool, dry place.
-
Regular Check-ups: Check the charge level of stored batteries every 3-6 months and top them up as needed to maintain the optimal storage voltage.
4. Cleaning & Inspection: Prevent Problems Early
-
Keep Clean and Dry: Regularly clean the battery case and terminals with a dry cloth to prevent short circuits or corrosion caused by dust and moisture.
-
Visual Inspection: Stop using the battery immediately and contact a professional if you notice any swelling, deformation, leakage, or damage. Never continue using a damaged battery.
5. Use Genuine Accessories: Trust Professional Quality
-
Always use the manufacturer-recommended or original charger, cables, and accessories. Incompatible chargers may not provide the correct voltage and current, potentially damaging the battery or creating a safety hazard.
We understand that manually following all maintenance rules can be challenging. Therefore, every battery pack manufactured by [Your Company Name] integrates an advanced smart Battery Management System (BMS). Our BMS acts as a "24/7 battery steward," working silently to provide:
-
Real-time monitoring of voltage, current, and temperature.
-
Automatic cell balancing to ensure consistency.
-
Multiple protections against overcharge, over-discharge, overcurrent, and short circuits.
-
This significantly reduces the complexity of manual maintenance, giving you greater peace of mind.
