Industries such as medical devices, security systems, and industrial uses often use ER or ERM batteries. These batteries are chosen because they provide long-lasting power and reliability. These fields rely on these strong batteries to keep their devices and equipment working well and effectively.

What are the maintenance and storage recommendations?

Store ER and ERM batteries in a cool and dry place. Keep them away from heat and moisture. Do not recharge them, as they can overheat or leak. To prevent short circuits, keep the battery ends away from metal. Avoid mixing old and new batteries or using different brands together. Protect the batteries from getting damaged. Check them regularly for leaks or swelling. Keep them out of reach of children and pets to avoid choking hazards. Always recycle used batteries properly through local programs.
