UPS Battery Maintenance


Batteries are the lifeblood of your UPS or telecommunications system, the power source for your standby generators and may provide backup power for your switchgear. In the event of a power emergency, batteries will provide continued operation of your computer, voice and data communications systems – but only if they work. Batteries used in UPS applications are typically VRLA type batteries and generally have a design life of 3-5 years for UPS up to 40KVA and 10-12 Years for larger KVA rated UPS. Failure to properly maintain your batteries or carry out regular checks can result in surprise failures in the battery when it is called upon to support the load. The key to ensuring the reliable operation of your battery backup is a comprehensive predictive maintenance and testing program.

IDCS offers preventive UPS battery maintenance specifically designed to minimize the risk of system downtime and provide you with peace of mind. We manage your battery systems under our preventative maintenance service plans and issue reports of their detailed condition. Because the average life span of a VRLA battery located in an optimal environment is approximately 5 years, we track the age and run-time capabilities of your batteries and issue proactive budgetary quotes to stay on top of your UPS battery backup system’s performance.

Preventive maintenance maximizes up-time and extends battery life by eliminating problems before they happen. Whether a battery fails from defect or deterioration, the best time to find out is during a preventive maintenance service, not during a power failure when critical loads might be compromised. We will custom design a Preventive UPS Battery Maintenance package that is best for you, including the following features:

Comprehensive maintenance for your V.R.L.A. or flooded batteries

Total battery terminal voltages

Spot checks for connection torques

Testing of cell/unit internal ohmic values

Measure of cell voltage levels

Visual inspection for leaks or bad cells

Inspection of battery environment

Detailed written inspection report of battery test and inspection results and recommendations for corrective actions

A battery maintenance contract with IDCS includes on-site inspections to uncover issues that may not be present in remote monitoring programs. Our technicians will assess any unforeseen battery vulnerabilities. We will minimize potential battery failure and mitigate any unnecessary battery risks. We will issue a full report tabulating and graphing the results of the maintenance check along with recommendations, if any issues were observed.

Where any battery has failed any checks, these will be resolved at the visit if possible or if not advice will be given as to best course of action for quick resolution. When your battery reaches 80 percent of its rated capacity, the ageing process accelerates and the battery should be replaced.
