Among design engineers, it is standard practice to adhere to a procedural selection process to choose the most suitable battery for an application or project. Various batteries, like the Duracell 150mAh or the swl2500efr UPS battery, are evaluated through an objective assessment that takes into account the technical requirements, performance, cost and future maintenance.
This predetermined process looks at variables such as charge and duty cycles, correction factors, system voltage, environmental conditions, location, original cost, cost of installation and future costs of servicing and replacement.
It is possible to alter the priority of factors. However, selecting the correct battery that is a perfect match for the application is the top priority. The performance levels and essential needs for usage plus capacity differences in different temperatures can impede considerations of other factors from the beginning, except if they are correctly set from the start.
Consequently, a determination on the life of the battery for the application as given by the vendor should be done. To accurately project the actual costs of the battery after initial costs, design engineers should consider the following:
- Make certain that initial costs cover the batteries, racks and shipment
- Set up complexity, if it varies for the different battery options in consideration
- Servicing commitment and the degree of maintenance complexity
- Battery lifespan before the need for replacement for the different battery types
- Dependability and reputation of battery models and their suppliers
- Agree on warranties and compare warranties from different vendors
After collecting information on technical needs and associated costs for various battery options short, intermediate and long term costs can be determined. This is where you provide an objective assessment of the project.
Creating an accurate projection of battery cost requires that you do the following activities on an ongoing basis.
- Seek advice from maintenance experts on current, emerging and future processes for servicing battery strings
- Higher or lower inspection visits
- Alterations to associated system servicing programmes
- Present workloads and future projections
- Number of personnel and required expertise level
- Remuneration and benefits
- The weight of battery and site maintenance
You must also explore modern maintenance apparatus. Examples of such tools are:
- Methods that reduce the time needed
- Improved settings around the battery
- Site observation, tracking and recording requirements
- Battery monitoring improvements that are cost effective and which reduce time and effort required
All these factors have to be assessed, analysed and quantified before deciding on the final solution. They must surpass the final criteria. Simply put the final and primary criteria is: is this choice the best to ensure that power never goes off?
Batteries are still lacking in in-built capability to independently report on their health status, but battery monitoring has progressively advanced in recent years. The staggering improvements mean that end users, maintenance providers and UPS manufacturers that have not done a comprehensive assessment of accessible Battery Monitoring Systems (BMS) are late to do so. BMS technology coupled with reduced costs has already made it possible to have remote site monitoring in the utility and telecommunication sectors. It is now convenient to monitor battery cabinets in remote locations with real-time and useful data being conveyed to end users for swift and prompt action.
For a search to be successful and meet the desired results, it is important to recognise the fact that backup battery power safeguards crucial data, services and hardware that are worth much more than the batteries.
Ultimately, the value of the batteries is higher than any amount paid. The real cost can only be determined by the value of what they protect and the damage that can be incurred if they fail.
It is reassuring to be guaranteed that power will continue uninterrupted even when there is a power outage from the grid.
