Beyond the standard range above, Power-Time develops customized KENWOOD-compatible battery solutions, including capacity upgrades, special housing and connector configurations, fuel-gauge (smart battery) implementations, intrinsically safe variants, and private-label projects for distributors. Send us the radio model and target specification for a feasibility review and quotation.
Our batteries are manufactured using premium lithium-ion cells sourced from leading suppliers including Panasonic, LG, and carefully selected Grade A cell manufacturers. Every battery undergoes comprehensive quality verification, including:
Built-in protection circuitry helps prevent overcharging, over-discharging, overcurrent, and short-circuit conditions while maintaining stable power delivery and long service life.
Clear audio communication is essential in demanding working environments. Power-Time manufactures a broad range of KENWOOD-compatible audio accessories covering tactical, surveillance, noise-suppression, bone conduction, and fire-ground communication needs, together with the microphones, cables, and amplification devices that complete a radio system.
Our KENWOOD-compatible audio accessories are available with the multi-pin connector types used across NEXEDGE, ProTalk, and legacy TK radio families, so a single accessory line can serve mixed radio fleets. Depending on the model, options include IP-rated water and dust protection, high-temperature cable construction for fire-ground use, and reinforced strain-relief terminations for heavy daily use.
Beyond the standard range, Power-Time develops customized audio accessories to meet specific requirements, including connector type, cable length and material, housing shape, PTT placement, microphone sensitivity, acoustic tuning, branding, and packaging. Send us your target radio model and specification for a feasibility review.
Quality control remains a core part of every product we manufacture. Our production and testing procedures include incoming material inspection, audio performance verification, battery testing, environmental testing, connector durability testing, cable flex testing, drop testing, and compatibility verification against the radio models and charging systems they are designed for.
Advanced testing equipment allows us to evaluate product performance at each production stage, so that every batch meets the reliability expectations of professional radio users.
In addition to standard products, Power-Time provides OEM and ODM services for communication accessories, including custom branding, packaging, connector specifications, and communication equipment compatibility needs.
Order lead time depends on product type and order scope. Standard production typically takes 3 to 5 weeks depending on order size, while OEM/ODM projects may require additional lead time. Contact our sales team for details specific to your requirements.

Send us your radio model number and the accessory type you need. Our team will confirm compatibility before you order. Compatibility is determined by the radio's connector type, battery form factor, and charging contact layout.
Yes. Our audio range includes fire-ground communication headsets designed for use with fire helmets and SCBA masks, helmet-mounted headsets for hard hats, throat microphone systems for respirator and extreme-noise environments, bone conduction headsets, and noise-cancelling headsets for high-decibel industrial work. Please confirm your helmet or mask model so we can recommend the correct mounting configuration.
Yes. Beyond earpieces and headsets, we supply vehicle microphones for in-vehicle radio installations and external amplified loudspeakers for vehicles, control rooms, and high-noise working areas, together with the connection cables and adapters required to complete an installation.
Yes. Our battery range covers NEXEDGE NX-5000, NX-3000, and NX-1000 series portables as well as ProTalk and legacy TK-series radios. Because different families use different battery form factors, please confirm your specific model when requesting a quote.
Yes. We offer custom branding, packaging, connector specification, and product development for distributors and communication equipment suppliers. OEM and ODM projects are handled separately from our standard product line, with dedicated lead times.
Standard production typically takes 3 to 5 weeks depending on order size. Minimum order quantity varies by product type. Contact our sales team with your target model list and quantities for a specific quotation.
Our products are manufactured under ISO 9001 quality management. Depending on the product category, certifications and test reports may include CE, RoHS, and UN38.3 for lithium batteries. Contact us to confirm documentation for a specific product.
