Chapter 7.9 - Comparison of Varigus Types of Cells
By Alexander C. King and William Knight
From UninterruptibJe Power Supplies and Standby Power Systems
Comparison of Various Types of Cells
A simple comparison of battery types used for a UPS system is detailed
below.
Prices are rated against Plante at 100 percent (which should give a
20-year life). All VRLA cells are rated at 1O-year design life, the exception
being the nickel-cadmium sealed cell, which should give a 20-year
life. Rating is 26.6 kW, autonomy period 15 min, float voltage is 409 V,
end of discharge is 306 V, or 180 lead acid cells float 2.27 VPC to end of
discharge 1.7 VPC. Ambient temperature 20°C.

The above figures are at best a rough guide, and economics may vary
with the power rating being considered
One should also bear in mind the life-cycle of the various cells. VRLA
cells are normally available with a design life varying from 5 to 10
years, and there is the possibility of increasing these figures. At least
one manufacturer claims a design life of 20 years, but under a strict
regime of operation. In the writer's knowledge most 1O-year design life
cells afford in practice a life of approximately 7 to 8 years.
