1. Why use VRLA batteries?
They are sealed, maintenance-free batteries that are safe for indoor use. They provide reliable backup without the need to add electrolyte or perform complex maintenance.
2. What is the difference between VRLA and Gel batteries?
AGM batteries are designed for fast discharges and high power, ideal for UPS systems and telecommunications. Gel batteries withstand deeper discharges and frequent cycles, making them ideal for solar and renewable energy applications.
3. Why consider Flame Retardant (FR) batteries?
These batteries, with their flame-retardant casing, increase safety in critical facilities such as data centers and hospitals.
4. What advantage do Front Terminal batteries offer?
They make installation and maintenance easier in racks and cabinets, optimizing space in telecommunications rooms and data centers.
5. How do I choose the right battery for my application?
Atlantic Power offers a Battery Sizing tool, based on the IEEE 485-2020 standard, which determines the exact capacity according to the load and required backup time.
6. What is a Valve-Regulated Lead-Acid (VRLA) battery?
Unlike conventional flooded batteries, VRLA batteries are sealed, maintenance-free solutions that do not require electrolyte refilling. Their sealed design prevents acid leakage or evaporation, ensuring safe operation in various applications. In addition, one-way safety valves automatically release gases when internal pressure exceeds safe limits, maintaining optimal pressure levels and ensuring reliability without external intervention.
7. What types of Valve-Regulated Lead-Acid (VRLA) batteries exist?
There are two main types: AGM (Absorbent Glass Mat) and GEL. AGM batteries use a fiberglass separator that absorbs and holds the electrolyte, preventing it from flowing inside the battery. GEL batteries use silica to solidify the electrolyte into a gel form. Depending on the application, VRLA batteries can be classified as starting batteries, stationary backup batteries, or traction batteries for motive power.
8. What is the end-of-discharge (EOD) or cut-off voltage of a battery?
The EOD voltage is the minimum permissible voltage to which a battery can be discharged. If the voltage falls below this level, over-discharge may occur, causing permanent damage. The EOD is directly related to the discharge rate: the higher the discharge current, the lower the effective capacity of the battery at that cut-off voltage.
9. What is the end-of-charge (EOC) voltage of a battery?
The EOC voltage is the point at which the battery is considered fully charged. At this stage, the active materials of the lead plates are saturated, and the battery voltage will no longer increase, even if charging continues.
10. What is the difference between floating use and cycling use of batteries?
Cycling use: The battery is used as a direct power source for equipment, undergoing repeated charge and discharge cycles. This is typical in renewable energy systems, electric mobility, and similar applications.
Floating use: The battery is kept at a constant state of charge and serves mainly as backup. It discharges only in the event of a power outage or emergency, as in UPS systems, power plants, or critical infrastructure.
11. What is float charging and equalizing charging in lead-acid batteries?
Float charging: The battery remains permanently connected to a constant-voltage source to preserve its charge. This ensures the battery is always ready for operation, especially in standby or emergency applications.
Equalizing charging: A controlled overcharge performed periodically to balance all the cells in the battery, prevent capacity differences, and extend its service life.
12. What are the requirements for proper battery storage?
Batteries should be stored in a clean, dry, and well-ventilated environment, on stable flooring, at temperatures between 15 °C and 25 °C. Even during storage, batteries must be recharged every 3 to 6 months to avoid capacity loss and sulfation.
