Shouldn Heavy-Duty or Super Heavy-Duty batteries work?
No. Unfortunately many terms used by the battery industry can be very misleading. “Heavy Duty” batteries are often the least powerful batteries you can buy and are a step down in quality. The term used to refer to zinc chloride batteries that had 50% more capacity than traditional carbon zinc batteries — but that was 50 years ago! Calling zinc chloride batteries heavy duty became misleading once alkaline batteries with 300% more capacity than zinc chloride batteries became available. Stick with factory recommended batteries.
