With a catalogue of over 250 standard models, MPD ensures that there is a solution for nearly every application.
Innovation in Coin Cell Battery Holders
MPD has a long history of leadership in the design of coin cell battery holders. In 1983, MPD invented and patented the first coin cell battery holder for general PCB placement. Since then, the company has continually refined and modernised its designs, creating an ever-growing selection to match the increasing number of devices that rely on coin cell power.
MPD has pioneered numerous innovative styles of coin cell battery holders to cater to the diverse needs of the electronics industry. Vertical holders save valuable space on crowded PCBs, while Mini holders reduce height by up to 3 mm compared to traditional designs. Glider holders provide stronger connections and tool-free battery replacement, offering a clear upgrade over coin cell retainers. MPD’s latest advancement, the Snap Dragon, introduces a snapping cover that adds extra reliability to the classic holder format.
Find the Right Size
MPD offers coin cell battery holders in nearly every size, including 191, 335, A76, CR1025, CR1216, CR1220, CR1225, CR1620, CR1632, CR2016, CR2025, CR2032, CR2320, CR2325, CR2330, CR2335, CR2354, CR2420, CR2430, CR2450, CR2477, CR3032, as well as F3 and F5 iButton, LR1120, LR44, ML414, SR512SW, SR60, V80H/CP1654, BR series, and many more. This broad coverage ensures engineers and designers can find the perfect holder for almost any application.
Coin Cell Retainers: Compact and Reliable
Coin cell retainers are a simple yet effective way to secure coin cells while maintaining electrical contact. Designed to take up little more space than the bare battery itself, they allow engineers to save valuable PCB real estate without compromising performance.
MPD coin cell retainers are crafted from nickel-plated metal, a choice that not only ensures strong electrical connectivity but also prevents galvanic corrosion. Since most coin cells are made with nickel shells, this material pairing delivers long-term durability and reliability.
Built for Automation
Every retainer from MPD is engineered with automation in mind. They can be easily picked and placed during assembly, with both through-hole and surface-mount options available to suit different production needs. This makes them a cost-effective solution, combining efficiency on the manufacturing line with the quality MPD is known for.
Wide Range of Sizes
MPD offers coin cell retainers to fit nearly every size, including 191, 335, CR1025, CR1216, CR1220, CR1225, CR1632, CR2016, CR2032, CR2320, CR2325, CR2330, CR2354, CR2430, CR2450, CR2477, F3 and F5 iButton, LR1120, LR44, ML414, SR512SW, SR60, V80H/CP1654, BR series, and many more. This extensive range ensures there is a reliable retainer solution for virtually any application.
9V Snaps: Simple and Economical Connections
9V snaps remain one of the most reliable and cost-effective methods for connecting 9V batteries. MPD offers a complete line of snap connectors designed to suit a wide range of applications.
Flexible Options
These connectors are available in both “I” and “T formats. The difference lies in the orientation of the battery contacts, parallel for the “I style” or perpendicular for the “T style.” This flexibility enables engineers to select the configuration that best suits their design.
Built for Every Application
To meet specific needs, MPD also produces snap variants such as -HD, featuring heavy-duty female contacts for extra durability, and -MC, which include moulded plastic covers for added protection. With such a wide variety available, MPD makes it easy to find the right 9V snap connector for your project.
Additional Products and Accessories
Battery Replacements
Some specialty batteries can be expensive or hard to source. To make replacements easier, MPD has developed innovative battery replacement holders. These holders are designed in the same shape as the original battery but use standard, readily available cells to match the electrical profile.
For example, the BA4D-S replaces a traditional lantern battery with four standard D cells. This not only reduces cost but also ensures that replacements are quick and practical, especially in emergencies when rare battery types may be unavailable.
Lead Acid Battery Clips
MPD also manufactures a reliable line of lead-acid battery connectors. Available in both alligator clip and block clip styles, these sturdy clips are built for secure and dependable connections. Their robust design makes them suitable for a wide variety of applications where lead-acid batteries are used.
