New: Procell Constant

Home > News > Products > New: Procell Constant

Procell Constant is the newest addition to their range of professional batteries. The Constant’s are replacing the standard Procell Alkaline cells, to complete the dual Portfolio, alongside Procell Intense. While the Intense range is designed for High Drain Devices, the Constant is perfect for Low Drain Applications. The new range is still available in AAA, AA, C, D and 9V sizes.

The most notable difference is the Longer Lasting Power (vs. prior Procell Alkaline batteries) in low drain devices. Which will reduce the amount of times you need to change the batteries in your application, saving on operating costs that come with battery replacement. The table below shows the improved capacity of the new range.

The Procell Constant range has also seen improvements in the manufacturing process and are now guaranteed with a 10 year shelf – that’s double the previous shelf life of 5 years compared to the Procell Alkaline. This makes them the ideal choice when managing stock levels to ensure that there is always a back up to the cells in use.

To help manage stock, each box and cell is date-coded for effective inventory management. The Procell Constant comes economically packaged in fully recyclable card board boxes of 10 bulk cells, with no plastic packaging.
