Smart Lock Exclusive Batteries 16PCS

• Install the battery correctly – Match the positive (+) and negative (-) ends to the device.
• Avoid short circuits – Do not connect the battery’s positive and negative terminals directly, as this can cause overheating, leakage, or even an explosion.
• Do not mix old and new batteries – Replace all batteries in a set at the same time to prevent over-discharge, which can cause leaks and damage to your device.
• Remove dead batteries promptly – Leaving depleted batteries inside a device can lead to leaks and potential damage.
• Store batteries properly for seasonal devices – If you're not using equipment like air conditioners or fans for a long time, remove the batteries to prevent leaks.
• Keep batteries away from children – Store them out of reach, and never let kids handle batteries without supervision.
• Clean battery contacts – Wipe the battery terminals and the device’s contacts occasionally to ensure a good connection and proper performance.
