7. Keep Batteries Clean and Dry: Keep batteries clean and dry underscores the importance of maintaining battery hygiene. Dirt and moisture can damage the battery contacts and lead to poor performance or failure. Regularly wiping the battery contacts with a dry cloth ensures good conductivity and performance. Industry guidelines recommend keeping electronic devices free from moisture and contaminants to preserve battery integrity.
