● design for the USP power supply applications ● long life (25 degrees C float use, the design life of up to 5 to 8 years) ● safer (shell with fire-retardant materials, products certified by UL safety) ● self-discharge (long storage time 1 to 2 years) ● good sealing (sealing reaction efficiency up to 99.9%) ● Distinguished Service (3-year warranty, quality assurance) OTP battery uses a unique multi-alloy formulations, the use of imported Cast-chip devices and self-developed grid mold, strict temperature control, the OTP battery grid not only the thickness, weight uniformity, the float long life, low self-discharge. Imported automatic computer-controlled lead powder machine the OTP battery to strict automatic control procedures to ensure the lead powder oxidation degree of particle size uniformity and stability, but also adapt to the battery current discharge characteristics.
