In today's world of well being the most reliable systems of support for global economy and communication network are powered by both AC and DC types of power sources. Therefore it becomes imperative to hold uninterrupted power supply, hence in order to augment this primarily we cater for unforeseen impediments for a reliable standby source where in the critical application contains as follows:
- For instantaneous switch over as per variable design source to fall back again on the main source.
- To support critical load for much greater time (several days?) until the primary source is restored viz Diesel generator/stationary battery banks.
What ever be the change in various technologies for the search of non maintenance batteries the VRLA (Value Regulated Lead Acid), various types of industrial batteries viz. tubular,plante,traction and ups, have still proved to be the most dependable source of power.
Why are not all batteries reliable ever with the best of the best manufacturer's warranty/guarantee?
It is very simple (No Rocket Science) most customers do not pay heed to the necessary drill of normal maintenance and routine checks of their alternate power source.
Honestly the value regulated Lead Acid batteries has to have a service life up to 5 to 6years but mostly the common cause for early demise is loss of water in the electrolyte thus causing loss of capacity while other causes also are prevalent.
