Installation Guidelines

For Tabbed Batteries (Soldering):

• Use low-temperature soldering (max 260°C)
• Solder quickly (less than 3 seconds per joint)
• Avoid overheating the battery
• Ensure proper polarity: positive (+) side is larger, flat surface
• Negative (-) side has the rim/edge

For No-Tab Batteries:

• Use appropriate battery holder or socket
• Ensure correct polarity orientation
• Verify secure contact with holder terminals
• Test voltage after installation

For XHR Connector:

• Simply plug into matching XHR socket
• Verify polarity before connecting
• Ensure secure connection
• No soldering required
