Safe Cleaning Procedure
First, switch off the equipment and disconnect it from external power. Work in a ventilated area away from heat, sparks, and flammable materials. Wear chemical-resistant gloves and safety glasses before removing the battery.
- Remove the battery without crushing, puncturing, or short-circuiting it.
- Place the damaged cell in a nonconductive container and follow local battery disposal requirements.
- Remove loose dry residue from the compartment with a disposable brush or swab.
- Clean metal contacts using a small amount of high-purity isopropyl alcohol, provided this method is permitted by the equipment manufacturer.
- Allow the compartment to dry completely before inspection.
- Replace contacts showing deep pitting, weakened springs, damaged plating, or unstable resistance.
Do not apply water, mix household chemicals, or attempt to neutralize unidentified lithium battery electrolyte. The chemistry of primary lithium batteries differs from alkaline batteries, so common alkaline-battery cleaning methods may be unsuitable.
Preventing Corrosion in OEM Projects
For products using a CR123A 3V lithium battery, corrosion prevention begins with correct cell selection and battery-compartment design. Designers should verify terminal pressure, contact material, polarity protection, storage temperature, pulse current, cutoff voltage, and protection against moisture ingress.
During OEM and ODM development, HOLITH reviews the operating current, installation direction, connector type, wire specification, expected service life, temperature range, and packaging requirements. A manufacturer can control cell assembly, sealing, aging, voltage screening, internal resistance testing, and batch traceability. A trader generally has less direct control over these quality checkpoints.
IEC 60086-1 covers dimensions, markings, performance testing, safety, and environmental aspects of primary batteries. IEC 60086-4 addresses the safety of lithium primary batteries, while UN 38.3 testing is commonly required before lithium cells and batteries enter international transport.
Bulk Supply Sourcing Checklist
Before approving a production order, confirm:
- Cell chemistry and rated capacity
- Maximum continuous and pulse current
- Leakage and sealing inspection records
- Lot identification and traceability
- Storage and transportation conditions
- UN 38.3, MSDS, RoHS, CE, and market-specific documents
- Sample approval and incoming inspection criteria
HOLITH uses automated production and testing equipment and reports annual output exceeding 40 million batteries. Direct manufacturing control supports consistent sealing, stable electrical performance, customized battery configurations, and reliable bulk supply for alarms, meters, medical devices, security systems, and tracking equipment.
