You may wonder asking about what is sealed maintenance-free batteries and what could be the
difference between it and traditional lead acid batteries. Which one is better and what is the
maintenance necessary for the battery?
We will answer all of that and more in this blog post.
Sealed Maintenance free batteries are the evaluation of the lead acid batteries manufacturing
technology. The lead Acid battery technology depends on chemical reactions between two different
types of Lead in an electrolytic solution of acid and water, these chemical reactions occurred inside
the battery generates emissions of gasses that must be vented from the battery to prevent
overpressure inside the battery that will be causes explosion of the battery. So first batteries of Lead
Acid were made with many vent holes to prevent any high pressure inside the battery, but that leads
the loss of the electrolytic solution level inside the battery, which decreases the connectivity of the
two different leads. Therefore, continuous observation of the solution level was mandatory every
periodic time to increase the solution level and keep the original ratio between water and acid from
the upper cap of every battery section, absolutely this was the most important maintenance
procedure and most dangerous one for the humans and environment compared with other
procedures like keeping the battery clean, tightly attached cables and keeping them isolated from
oxidation.
As humanity and the environment are always important, the manufacturing technologies keep
evolving, trying to minimize the emissions of these gases and rise the overall battery efficiency by
minimizing the self-discharge rate, internal resistance, and corrosion. Many technologies and
chemical formulas are invented and succeeded to maintain those issues as the gases emissions are
minimized to the level that the vents are no longer needed to be replaced with only one tight vent to
handle the tiny amount of gas emissions that could appear at the end of the battery life cycle. Which
allowed the battery to be fully sealed except for the tight vent that allows extraction only of extra
emissions to prevent burst or explosion and gives the chance for another checking indicator
technology to existing like the Magic Eye to be the process of the battery check easy as indicating
the eye’s color green, black, or white. Then humanity and the environment won longer battery life
with fewer emissions, higher efficiency, and a full recycling process.
We at Chloride Egypt collaborates in inventing and enhancing the lead acid battery technologies to
provide the best power solution for the environment, humanity, and the application to perform
maximum quality. Technologies like Ca-Ca alloy, expanded metal, and encapsulated negative plates
separators from polyethylene envelopes used by Chloride Egypt boost battery efficiency and let our
clients enjoy an easy high cold start, very low self-discharge rate, high resistance to overcharging,
and many more features that make Chloride the best performer in all situations.
