The Michael Kors MK5039 is a stylish and sophisticated timepiece, but like all quartz watches, it relies on a small but crucial component: the battery. Knowing how to replace the battery and understanding the type required is essential for keeping your MK5039 ticking accurately and reliably. This article delves into the specifics of the Michael Kors MK5039 battery, exploring compatible options, replacement procedures, and common issues encountered during the process. We'll also discuss where to source reliable replacement batteries and offer advice on extending the lifespan of your watch battery.
Identifying the Correct Battery: Energizer 371/370 (SR920W/SR920SW)
The Michael Kors MK5039 typically uses an Energizer 371 or 370 battery, which are also commonly known as SR920W and SR920SW. These are silver oxide button cell batteries, renowned for their stability and long lifespan compared to other battery chemistries. The "SR" designation refers to the battery's size and type, while the numbers indicate specific dimensions. The "W" and "SW" suffixes might refer to slight variations in manufacturing or packaging, but functionally, they are virtually interchangeable for use in the MK5039. It's crucial to use the correct battery type; using an incorrect size or chemistry could damage the watch movement.
Understanding Silver Oxide Batteries
Silver oxide batteries are a popular choice for watches due to their several key advantages:
* High energy density: They pack a significant amount of power into a small package, providing a longer lifespan than some other battery types.
* Stable voltage: They maintain a relatively constant voltage throughout their discharge cycle, ensuring consistent watch performance.
* Long shelf life: Even unused, silver oxide batteries retain their charge for a considerable period.
* Low self-discharge rate: They lose charge very slowly when not in use.
However, they also possess some limitations:
* Sensitivity to moisture and temperature: Extreme temperatures or exposure to moisture can affect their performance and lifespan.
* Not rechargeable: Silver oxide batteries are single-use and must be replaced when depleted.
Where to Buy Replacement Batteries: Online and Offline Options
Finding replacement batteries for your Michael Kors MK5039 is relatively straightforward. Several avenues are available:
* Amazon.com: Amazon offers a vast selection of watch batteries, including the Energizer 371/370 (SR920W/SR920SW), often in multi-packs for cost-effectiveness. Searching "Michael Kors Watch Battery Replacement" on Amazon.com will yield numerous results, allowing you to compare prices and reviews. Look for reputable sellers with positive customer feedback to ensure you receive genuine batteries. The convenience of online shopping is undeniable, allowing for easy comparison and home delivery. However, be mindful of shipping times and potential delays.
* Local Jewelers and Watch Repair Shops: Local jewelers and watch repair shops are excellent resources for battery replacements. They often stock a range of watch batteries and can provide on-the-spot replacement services. The benefit of using a local shop is the immediate service and the possibility of getting advice on proper battery installation and watch maintenance. However, the cost may be higher than purchasing batteries online.
* Electronics Stores: Some electronics stores, particularly those specializing in components, may also carry watch batteries. This could provide a convenient option if you need a battery immediately.
