CR2025PH 3V 165mAh Lithium Manganese Dioxide Battery: The Gold Standard in Automotive Proximity Power
Overcoming the Silent Killer of Modern Smart Keys: Signal Dropout
As vehicles transition to bidirectional Passive Entry Passive Start (PEPS) systems, your car key is constantly talking to your car. This constant background communication requires sudden, aggressive pulse currents to transmit rolling security codes. When standard commercial coin cells face these high-drain pulses, their voltage dips, causing delayed unlocking, dashboard battery warnings, or total signal dropout.
De CR2025PH eliminates this vulnerability. The “PH” aanduiding staat voor onze eigen ontwikkelde Power High (Hoge Capaciteit) formulation. By cramming an extraordinary 165mAh into the industry-standard 20mm x 2.5mm blueprint, we give automotive remotes the stamina to punch through interference, winter freezes, and summer heatwaves.

Strategic Value Pillars of 3V 165mAh Lithium Manganese Dioxide Battery
1. The “PH” 165mAh Power Advantage
While common off-the-shelf CR2025 cells hover around 145-150mAh, our PH engineering optimizes the inner active material density. This yields a massive 165mAh capacity. For your customers, this translates directly to fewer battery replacements and zero early-life low-voltage warnings on premium vehicle displays.
2. Automotive-Grade Thermal Hardening (-20°C to 70°C)
Car keys live an unpredictable life—dropped on frozen concrete or baked inside a glovebox under direct sunlight. The CR2025PH features a stabilized electrolyte solution that prevents the sluggish chemical kinetics caused by extreme cold, and resists internal pressure spikes caused by extreme heat.
3. Anti-Leakage Hermetic Shielding
Modern electronic keys are expensive investments. To safeguard internal PCBs, the CR2025PH is manufactured with a strict automated crimp-seal structure and a localized anti-oxidation layer. This ensures absolute protection against acid creeping or structural leakage over its entire operational lifecycle.

Veelgestelde vragen
What does the “PH” indicate on the CR2025PH battery? De “PH” staat voor Power High / Hoge Capaciteit. It indicates that the battery utilizes an upgraded, high-density chemical formulation allowing it to achieve a 165mAh capacity, meaning it lasts significantly longer than standard commercial 150mAh CR2025 variants under heavy pulse-load conditions.
Why is the CR2025PH preferred for car keys over standard CR2025 cells? Standard cells lack the thermal endurance and pulse-current stability needed for modern smart keys. The CR2025PH is rated for automotive environments (-20°C to 70°C), preventing the voltage drops that lead to ignition connectivity failures or weak remote range.
