lead technology , it is now possible to match the life expectancy offered by Lithium-ion with the additional safety , recyclability and lower costs of lead acid technology .
Advanced pure lead – why is it different ?
Two key components are key to determining battery life : the grid and the paste . The paste generates the energy in the battery while the grids transfer energy to the terminals so it can be used . Due to normal operations of batteries , the grids will corrode , and the paste will dry out . The speed at which this happens is what will determine battery life .
Standard VRLA batteries use a mix of lead and other elements to achieve a good balance between cost and life .
However , due to the presence of other elements , and a simpler manufacturing process , they are limited in terms of performance , heat tolerance and even storage time .
Pure lead batteries use higher purity materials ( virgin lead ), along with other manufacturing improvements to help reduce the rate of grid corrosion and paste dry-out .
Thanks to these advancements , pure lead batteries have an extended life , increased runtime , prolonged storage time and improved heat tolerance . It ’ s important to note there isn ’ t a single way to make a pure lead battery , so every manufacturer will have a unique approach .
Building on the solid pure lead foundation , the advanced pure lead technology takes life expectancy closer to Lithium-ion by introducing a catalyst to further delay paste dry-out .
While catalysts are not new to the industry , adding them to a 12V pure lead battery is , and it allows us to achieve the resulting 7 – 10-year life expectancy .
A future-focused strategy
By thoroughly understanding the different battery chemistries and their applications , you can make decisions to safeguard your operations and futureproof your investment and growing power demands .
A comprehensive , thoughtful and inclusive approach ensures your battery backup solution will support your current needs and adapt seamlessly to future demands and advancements . �
