C & D Batteries.

Powerful C and D batteries for business and industry

When professional equipment requires high energy output over a longer period, C or D batteries are the natural choice. These robust power sources are built to deliver high and consistent capacity in demanding work environments, whether it’s security services, industrial operations or large-scale facility management. By ordering your batteries in bulk, you significantly reduce the unit cost.

The difference between battery sizes C (LR14) and D (LR20)

Both C and D batteries are cylindrical, robust, and have a standard voltage of 1.5 V for alkaline types. The difference lies in their physical size and therefore how much energy they can store:

• Battery size C (LR14 / Baby): Slightly smaller and lighter. Commonly used in medium-sized professional flashlights, medical equipment and portable measuring instruments.
   
• Battery size D (LR20 / Mono): The largest of the standard cylindrical sizes. Delivers extremely long operating time and is ideal for high-consumption equipment such as heavy-duty dispensers, megaphones and large industrial flashlights.
   

Maximize ROI with rechargeable C and D batteries

For equipment used daily, switching to rechargeable batteries (NiMH) is a cost-effective investment. A rechargeable C or D battery can often be recharged up to 1,000 times. Although the initial purchase cost is higher, it quickly pays off for businesses such as security companies and industrial operations with continuous energy consumption. Combine with one of our professional battery chargers to minimize downtime.
