In summary, among battery-driven power management solutions, there are numerous alternatives because competing battery chemistries differ significantly with regard to cost, performance, safety and durability. Several factors need to be considered when choosing the appropriate MPD battery holder for a wireless application, such as environmental factors and battery access and replacement. Designing a battery holder for a remote wireless application often is complex and requires the consideration of design restrictions related to size, weight, power and cost factors. Many battery holders are available from MPD that meet the design requirements of various wireless applications.
