High-energy batteries for low-maintenance systems

A new range of high-energy long-life batteries will benefit applications in low-maintenance systems such as remote sensing instruments and computer memory backup.

A new range of high-energy long-life batteries will benefit applications in low-maintenance systems such as remote sensing instruments and computer memory backup.

Based on lithium thionyl chloride chemistry, the new Dubilier batteries match the performance of leading brands, but are offered ex-stock at highly competitive pricing.

Lithium thionyl batteries have a nominal cell voltage of 3.6V, a very high energy density, a long shelf life and a good temperature range.

Their nominal voltage is the highest among all lithium batteries, and more than twice that of manganese dry batteries and alkaline dry batteries.

The batteries' high energy density is made possible by the use of highly active thionyl chloride as the positive active material.

As a result, they achieve a capacity of 2200mAh in an AA can - which compares very favourably with comparable size batteries of more traditional chemistry.

A key feature of this chemistry is the minimal internal resistance variation during discharge, assuring a stable operating voltage even during an instantaneous high current discharge.

As a result, the batteries are specified with a maximum discharge current of 10 to 1800mA depending on size, providing a high level of power to run, for example, a system shutdown in the event of power failure in a battery backup application.

Other features contributing to their low-maintenance characteristics in unfavourable environments include their extremely wide temperature range, -55 to +85C, and their robust hermetically sealed stainless-steel cans.
