Exact fitment is critical for key fob components. A misaligned battery can prevent proper closure or damage internal contacts. This battery ensures seamless integration into the designated BMW key fob housings. It fits perfectly.
Unlike generic batteries, which often require modification or do not sit flush, this replacement is engineered to match OEM dimensions. This precision minimizes installation complications. It saves time and effort.
The battery operates at a nominal voltage of 3.7V, providing a capacity of 580mAh, and delivering 2.14Wh of energy. It is a Li-ion (Lithium-ion) type battery. These specifications are crucial for consistent power delivery.
These electrical parameters are vital for the key fob's operational integrity. A 3.7V output ensures stable power to the internal electronics. The 580mAh capacity dictates the operational duration between charges or replacements. This ensures reliable key fob function.
Under-spec'd batteries can lead to intermittent performance or reduced signal range. This battery's specifications align with the power demands of the listed BMW key fobs. It offers dependable power.
This replacement battery incorporates multiple protection circuits. These include overdischarging protection, overcharging protection, current protection, reset protection, overheat protection, and voltage protection. These features are fundamental for battery health.
Each protection mechanism safeguards both the battery and the delicate key fob circuitry. Overcharging protection prevents thermal runaway. Overdischarging protection extends the battery's lifespan. Current protection mitigates short-circuit risks. This ensures safe operation.
Unprotected generic batteries pose significant risks, including swelling, leakage, or even fire. The comprehensive suite of protections in the MKD35UP offers enhanced safety. It provides peace of mind.
The battery is encased in an ABS+PC shell. This material choice is noted for its heat and wear resistance. The outer casing protects the internal cell.
An ABS+PC composite shell provides superior durability compared to standard plastics. Key fobs endure daily handling, drops, and temperature fluctuations. This robust shell helps the battery withstand such stresses. It resists physical damage.
Cheaper battery casings can crack or deform, exposing the cell to damage. The enhanced material properties of this shell contribute to the overall longevity of the replacement battery. It offers lasting protection.
The product package includes a set of small installation tools. These consist of blue and black screwdrivers and a white plastic pry tool. These tools facilitate the replacement process.
These specialized tools are essential for safely opening the key fob without causing damage. The screwdrivers are sized for the tiny fasteners often found in such devices. The pry tool helps separate plastic casings without marring surfaces. It simplifies the repair.
Sourcing appropriate tools separately can be inconvenient and costly. The inclusion of these tools adds significant value for the end-user. It makes DIY repair accessible.
The battery carries multiple international certifications. These include CE, FCC, RoHS, and ECT certificates. These attest to product compliance.
These certifications signify adherence to stringent safety, environmental, and electromagnetic compatibility standards. CE marking indicates conformity with European health, safety, and environmental protection standards. FCC certification ensures electromagnetic interference is within limits. RoHS restricts hazardous substances. This confirms product quality.
Uncertified components may not meet these critical standards, potentially leading to safety hazards or environmental concerns. The presence of these certifications provides an assurance of quality and regulatory compliance. It builds user confidence.
This battery is suitable for various applications. These include refurbishment, repair, distribution, and personal use. Its versatility is a key attribute.
For repair shops, this battery offers a reliable component for servicing BMW key fobs. Individuals can perform DIY replacements, saving on dealership costs. Distributors can stock a certified, compatible part. It serves multiple needs.
Opting for a direct replacement battery like the MKD35UP is often more cost-effective than replacing an entire key fob. It extends the life of existing hardware. This is a smart choice.
Restoring a key fob's power means regaining seamless access to your vehicle. Imagine the convenience of a fully functional key fob, reliably locking and unlocking your BMW without hesitation. The frustration of a dead battery becomes a distant memory. This replacement ensures consistent performance, allowing you to operate your vehicle's remote features with confidence and ease, every single time you reach for your keys. The included tools make the process straightforward, letting you quickly return to effortless vehicle interaction.
