Import Tips
• Cross-reference LR44 alkaline part numbers but classify by actual silver oxide chemistry, not model number
• Batch test capacity (>140 mAh for LR44-size) to distinguish low-grade cells from premium silver oxide
• Comply with California Prop 65 warnings for battery products containing trace heavy metals
