Battery Care Tips for Industrial Handhelds: Avoid full discharge (keep above 20%). Keep away from high temperatures. If swelling occurs, stop use immediately.

🔋 90-day warranty is the industry standard for replacement batteries. Batteries naturally lose capacity over time — this normal wear is not covered. Warranty applies to manufacturing defects only.
