Driven by the widespread adoption of global mobile office and on-site field operations, portable printers have become essential equipment across multiple sectors including logistics & courier, supermarket retail, medical care, warehouse management and catering delivery. End-users prioritize instant receipt printing, mobile usability, lightweight design and dependable durability. As the core power source of such devices, lithium batteries directly determine runtime, printing stability, environmental adaptability and operational safety, serving as a decisive factor of product competitiveness. With over 24 years of specialized R&D and manufacturing of lithium polymer batteries, Shenzhen BPI Battery Co., Ltd. implements automotive-grade quality control and holds multiple international safety certifications. We develop customized high-performance lithium battery solutions exclusively for portable printers to supply steady, durable and safe power for all types of mobile printing equipment.
Portable printers frequently operate outdoors, inside vehicles, in cold chain facilities, cold storage rooms and high-temperature warehouses with drastic temperature swings. Conventional batteries commonly suffer unexpected power loss in low temperatures or swelling/erratic discharge under high heat.
BPI’s dedicated lithium batteries feature an operating temperature window of -20℃ ~ 60℃, suitable for most harsh working environments.
The cells retain favorable discharge capacity in frigid conditions to ensure smooth startup without unexpected power drop or automatic shutdown.
Internal impedance stays low and heat generation is minimized under high temperatures, drastically cutting risks of cell swelling and electrolyte leakage.
Consistent power supply guarantees normal printer operation amid extreme cold, intense heat, enclosed spaces and humid surroundings.
Adopting a 2S1P cell configuration with a rated voltage of 7.4V, the batteries deliver a flat discharge curve with marginal voltage drop and consistent output performance.
Stable power input effectively avoids common operational defects such as intermittent printing, paper jams, faded print characters and uneven paper feeding.
High energy density design maximizes capacity within limited internal space, balancing compact form factor and long continuous usage time.
A full single charge supports 4 to 8 hours of intensive non-stop printing to satisfy all-day field work requirements for field operators.
Low self-discharge characteristic enables long-term shelf storage without power depletion for instant on-demand use.
Low-impedance cell design improves energy conversion efficiency with minimized internal power loss and prolonged service lifespan.
Per IEC standard cycle testing, the batteries achieve ≥500 charge-discharge cycles with slow capacity degradation and stable long-term performance.
Longer service life reduces regular battery replacement frequency and cuts end-users’ total ownership expenses.
Lower after-sales maintenance burdens for equipment manufacturers while boosting product durability and market reputation.
Customizable dimension, capacity, wire outlet direction and cable length based on each printer’s internal layout constraints.
Bespoke connector design enables direct plug-and-play matching with mainboard terminals without mechanical modification to equipment housing.
Flexible pouch-type Li-Polymer cells feature slim profile and excellent malleability to fit compact inner spaces without spoiling device appearance or hand grip.
Perfectly compatible with handheld receipt printers, Bluetooth label printers, logistics waybill printers and industrial portable printers.
Fast customization turnaround shortens clients’ product development cycles and accelerates mass production scheduling.
Built-in five-fold intelligent protection against overcharging, overdischarging, overcurrent, short circuit and overheating.
Equipped with professional BMS (Battery Management System) to monitor real-time voltage, current and temperature and activate automatic protection upon abnormal conditions.
Pouch aluminum-laminated film structure delivers stable chemical properties with benign failure mode and zero explosion hazards.
Compliant with global consumer and industrial electronic safety criteria, facilitating CE, UL certification approval and smooth product market access.
