What the thread found

• The Heden Carat handset can experience rapid battery drain even when powered off, which may indicate a defective unit or battery batch issue.
• Lithium-ion rechargeable 9V batteries provide better runtime than alkaline cells, lasting most of a full shooting day.
• Some users report that rechargeable lithium-ion batteries perform better than alkaline batteries for this device.
• Repeated battery removal and reinsertion can stress the connector wires over time.
• The 9V connector may require occasional tightening to maintain proper power contact after multiple battery changes.

Depends on

• The drain-when-off issue was resolved for one user by switching battery brands, suggesting it may be a battery compatibility problem rather than a universal design flaw.
• Reported runtimes for rechargeables vary between users, ranging from 5-6 hours to nearly a full day.
• Some users report that professionals they consulted advised against rechargeables, though this contradicts positive experiences from others.
• The connector durability concern is anecdotal and based on potential long-term wear rather than documented failure.
