UPS & Inverter Batteries

A battery is a device which produces electricity by the method of electro chemical reaction. A battery consists of positive plates , Negative Plates and an electrolyte. A battery has a positive terminal and negative terminal. Usually the type of batteries used in UPS applications are ‘lead acid’ batteries (Wet batteries since it contains water). The positive and negative are made up of lead oxides and sulphuric acid as the electrolytes.

Batteries are the storage devises for power. The utility power is in AC form and batteries store it in DC form. The charger section of UPS facilitates this. There are generally three types of batteries, namely, Automotive, Tubular and SMF (Sealed Maintenance Free). Automotive batteries are used for vehicles where discharge is deep for a short duration. Tubular batteries are designed for deep discharge for long durations such as in the case of UPS applications. Both Tubular and SMF are used for all industrial uses including UPS.

Battery is the main storage power for any UPS system. Each UPS may be designed with a specific battery voltage. Batteries are available in different voltages and different capacities. Batteries are available in different voltage ratings such as 2V, 6V, 12V, etc of which 12V is the most popular of all the lot. Suppose a UPS is designed with 120V DC battery voltage. it requires at least 10 nos of 12V batteries to work the system. The size of each of these batteries determine the backup time available after power failure. Battery capacity is measured as AH(Ampere Hour) and will vary from say 1AH to 300AH. Generally the bigger the battery, more is the AH it will have and gives longer back up.

Some Key Features of Tubular UPS & Inverter batteries:

  • SPECIAL PLURI TUBULAR POSITIVE PLATES: For long service under deep cycle usage
  • LOW ANTIMONY: Designed with low antimony content to minimize water loss & thereby reduce the topping requirement.
  • SPEIAL MICROPOROUS SEPERATORS: To permit free exchange of ions & prevent shot circuit risks.
  • BATTERY SHELL: A high impact, versatile, leak proof & durable hard rubber container with multiple lids.
  • VENT PLUG: Specially designed vent plugs and cell covers to prevent leakage of acid, fumes and Gases, thus providing the connectors and terminals from corrosion and providing safety.
  • "We have been using Unipar 5KVA UPS for the last 5years. Their service rendered has been extremely good and has been always been prompt ontime. We would always recommend their service just for their sheer quality and service rendered."
