CR1632PH 3V 140mAh Battery High-Capacity Automotive Grade Coin Cell
CR1632PH 3V 140mAh Lithium Manganese Dioxide Battery: Heavy-Duty Automotive-Grade Energy
The Evolution of the Key Fob Demands More Than a Standard Battery
Modern vehicle remotes are no longer just passive clickers; they are active, bidirectional computing devices. Features like Passive Entry Passive Start (PEPS), remote climate pre-conditioning, and digital screen alerts draw continuous background energy and high-frequency pulse currents.
When standard commercial batteries fail under these heavy drain demands, drivers get stranded.
Enter the CR1632PH. The “PH” moniker stands for Power High (High Capacity). By packing an exceptional 140mAh capacity into a sleek 16mm x 3.2mm form factor, this battery delivers up to 25% longer operational life than standard cells, setting a new benchmark for Tier-1 automotive supply chains.

Engineered for B2B Procurement Priority
1. The “PH” High-Capacity Edge (140mAh)
While consumer-grade CR1632 batteries typically peak at 120-125mAh, our specialized PH chemical engineering optimizes internal volume efficiency. This provides a robust 140mAh reservoir, ensuring the battery handles sudden high-current bursts (like starting an engine from 50 meters away) without voltage dips.
2. Extreme Climate Defense (-20°C to 70°C)
Automotive components endure the harshest thermal shifts. Left in a vehicle during a sub-zero blizzard or under a sun-baked windshield, the CR1632PH maintains structural integrity and electrical output, preventing localized interior outgassing or frozen cell failures.
3. Anti-Corrosion & Heavy-Duty Seal Technology
Leaky batteries ruin expensive smart key modules. Our CR1632PH is manufactured using automated precision-crimping and advanced sealing materials, boasting a near-zero leakage rate under prolonged high-temperature exposure.

Frequently Asked Questions
What exactly does the “PH” indicate on the CR1632PH battery? The “PH” prefix denotes our proprietary High-Capacity / Power-High formulation. It means the battery is engineered with elevated energy density to reach 140mAh, specifically designed to withstand the heavy pulse currents of automotive smart key architectures, outlasting standard CR1632 variants.
Why is the CR1632PH classified as an “automotive-grade” battery? It earns this classification due to its resilient operating temperature envelope (-20°C to 70°C) and robust pulse-discharge design. It guarantees reliable remote-to-vehicle handshakes even under severe environmental conditions that typically cause standard consumer lithium cells to drop voltage.
