key specifications of a typical VRLA (Valve-Regulated Lead-Acid) battery: 1. Voltage: Typical individual VRLA batteries are available in voltages like 2, 6, and 12 volts. 2. Capacity: The capacity of VRLA batteries can range widely, often from a few ampere-hours (Ah) to over 200 Ah, depending on the application.
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.
VRLA battery packs consist of three to four 12 V modules (12, 14, or 20 Ah capacity) for a total voltage of 36 or 48 V and energy capacity of 0.4–1 kWh. Valve-regulated lead–acid for E2Ws differ from starting, lighting, and ignition (SLI) VRLAs used in automotive applications in that they are able to be deep cycled.
The reserve capacity is the time in minutes that a new, fully charged battery can be continuously discharged at 25 amperes and maintain at least 1.75 volts per cell (10.5 volts for a 12-volt battery).
In this revision, particular reference is made to ‘General Definitions’, ‘Product Characteristics’, ‘Design Life’, ‘Service Life’ and ‘Safety’. 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.
Excessive ripple on the DC supply across a battery has the effect of reducing life and performance. It is recommended, therefore, that voltage regulation across the system, including the load, should be better than +/- 1% between 5% to 100% load, without the battery connected and under stable state of conditions.
VRLA battery
A valve regulated lead–acid (VRLA) battery, commonly known as a sealed lead–acid (SLA) battery, [1] is a type of lead–acid battery characterized by a limited amount of electrolyte ("starved" electrolyte) absorbed in a plate separator or formed into a gel; proportioning of the negative and positive plates so that oxygen recombination is ...
