Frequently Asked Questions — Power Supply Battery

What is a power supply battery used for?
Power supply batteries (VRLA sealed lead-acid) are used as backup power for UPS systems, telecommunications, alarm and security systems, medical equipment, emergency lighting, and home or commercial power systems. They are fully sealed and maintenance-free.
What is the difference between cyclic and floating applications?
Cyclic application means the battery is repeatedly charged and discharged — for example, powering a device during outages. It supports over 260 deep cycles. Floating application means the battery stays connected to a charger continuously (trickle charge), as in a standby UPS, with a typical service life of 3–5 years.
How long does a power supply battery last?
In floating (standby) use, power supply batteries typically last 3–5 years. In cyclic use they support over 260 deep discharge cycles. Actual lifespan depends on ambient temperature, depth of discharge, and charging frequency.
What Ah capacity do I need for my UPS?
Use this guide formula: Ah = (load in watts × backup hours) ÷ (battery voltage × system efficiency). For example, a 200W load requiring 1 hour of backup on a 12V system at 80% efficiency needs approximately 21 Ah. Always consult your UPS manufacturer's specification for the recommended battery rating.
Do power supply batteries require maintenance?
Thaihuawei VRLA (Valve Regulated Lead-Acid) power supply batteries are fully sealed — no electrolyte top-up needed, no leaks, safe for indoor installation. Check voltage and capacity every 6–12 months, and replace when the battery reaches 3–5 years of age or shows reduced performance.
