Battery manufacturer Yuasa Battery Sales unveiled its latest advanced nano-carbon valve regulated lead-acid (VRLA) batteries at the Data Centre World 2015 event in London.
The battery was designed for use in large energy storage and remote renewable power applications where frequent charge/discharge cycles are encountered.
A Yuasa spokesman told BEST: “This battery has been in development for 5-7 years. VRLA batteries have been around for 30 years and if you design a new product it usually takes 12-18 months, but this particular technology is for such a specific application.
“It’s the type of use for when you need high cycle demand.” He added: “When launching a new product, before anything, you have to make sure it works correctly before it goes out to customers, because the last thing you want is back-up power that doesn’t work.”
The SLE-1000 and SLR-1000 batteries feature advanced nano-carbon technology for deep long cycle life, specifically for use in large capacity applications such as renewable storage.
Smaller than traditional batteries the SLE-1000 offers up to 3000 deep discharge cycles at 50% depth of discharge (DoD).n It also features a nominal voltage of 2V and nominal capacity of 1000Ah/10hr.
Maximum discharge rate is 1000A and the batteries can be used between -15 to +45°C.
Alternatively the SLR-1000 batteries are designed for frequent discharge cycles. The at 1000Ah/10hr nominal 2V high capacity cyclic cells can be deployed in large energy storage applications and offer up to 5000 cycle life at 50% DoD.
