China (Mainland) Maintenance Free Batteries Electric Devices

Specifications: 6v,6.5ah. NW1.35kg DYNAVOLT’s unique construction and sealing technique guarantee that no electrolyte leakage can occur from the terminals or case of any DYNAVOLT battery. This feature insures safe, efficient operation of DYNAVOLT batteries in any position.

During the expected float service life of DYNAVOLT batteries, there is no need to check the specific gravity of the electrolyte, or add water. In fact, there is no provision for these maintenance functions.

The heavy duty lead calcium-alloy grids in DYNAVOLT batteries provide an extra margin of performance and service life in both float and cyclic application, even in conditions of deep discharge.. All of our DYNAVOLT SLA batteries have already passed UL test. Positive plates and negative plates are made from a Lead–Calcium system.

The glass fiber separators in DYNAVOLT SLA batteries have resistance to acid. The high porosity of the separators retains adequate electrolyte for the reaction of active materials in the plates.

The venting system, which operates at 1psi to 6psi(0.07-0.43kg/㎡) is designed to release excess gas and keep the internal pressure within the optimum range of safety, while it protects the negative plates from contamination from oxygen in the air. Vents are 100% visually inspected during battery production.

Standard case and cover are manufacture from ABS resin.
