Substation Batteries
Substation Batteries
(OP)
Our current flooded cell, station-class battery standard allows either Selenium or Antimony-type batteries. In the past Calcium-type batteries were used, but inherently had some problems concerning plate growth, affecting reliability and durability. Since then, it is understood that there have been advances in design that, in theory, take care of the problems that existed in the past.
-Do you currently use Calcium-type batteries?
-If so, has plate growth been a problem?
-Are there any new issues that have come up concerning this type of battery (Has Reliability, Durability, etc. been effected.)?
-Do higher float and equalize voltages cause any operating concerns (switchgear, etc.)?
-Any particular manufactures to look at for calcium-type batteries?
-Any other bad experiences? Good experiences?
Thanks in advance for the input.

RE: Substation Batteries
Yes one of the facilities I used to work in had Ca and YES we had problems with buckling and expansion of the plates within the first year. The expansion of the plates was so severe that it was popping open the top coves of the containers. We did register an increase in the internal resistance of the batteries and decrease in sp gravities of the cells. All this happened during the first year after commissioning of the batteries, which was the defect libiality period, and the supplier had to replace the batteries with Ca free type.
I am afraid it won't be appropriate to disclose the name of the manufacturere in this forum.
