6 FAQs about [What is the maximum current of a valve-regulated battery ]
What is a valve regulated battery?
The valve-regulated version of this battery system, the VRLA battery, is a development parallel to the sealed nickel/cadmium battery that appeared on the market shortly after World War II and largely replaced lead-acid batteries in portable applications at that time.
Why should lead-acid batteries be valve regulated?
Thus, the strong position of lead-acid batteries in this field will be improved by the valve-regulated design, and they will remain in widespread use in the future. Furthermore, the VRLA design opens applications for lead-acid batteries where acid stratification had been an obstacle for the vented design.
What is the maximum current allowed in a battery?
TABLE 1. MULTI-RATE, CONSTANT CURRENT CHARGING The region in Table 1 indicates a maximum current allowed of C/2 (50 amperes per 100 AH of rated capacity), and a switching voltage of 2.45 v/c. Naturally, lower currents may be used, which will reduce battery heating, resulting in greater recharge efficiency and lengthen the recharge time.
What is the limiting current of a battery with liquid electrolyte?
In conventional batteries with liquid electrolyte, this limiting current is very small, since the diffusion rate of dissolved oxygen is very slow, and as consequence, the equivalent of oxygen reduction is limited to a few mA per 100 Ah of nominal capacity and thus is hardly noticed in battery practice. 3. The valve-regulated version
What is the IEC/EN Guide to Valve Regulated Lead-acid batteries?
This guide to IEC/EN standards aims to increase the awareness, understanding and use of valve regulated lead-acid batteries for stationary applications and to provide the ‘user’ with guidance in the preparation of a Purchasing Specification.
What is a valve regulated cell?
A valve regulated cell or battery is closed under normal conditions by a non-return control valve that allows gas to escape if the internal pressure exceeds a predetermined value. The valve does not allow gas (air) to enter the cell.
