Before installing the new battery, use a multimeter to verify its voltage (should be around 3.7V to 4.2V when fully charged). This ensures the replacement battery is functional and compatible with the four 40W Seviz battery replacement requirements.

Step 5: Install the New Battery

Place the new 1500mAh lithium-ion battery in the same position as the old one. If soldering is required, carefully solder the wires to the appropriate terminals, ensuring correct polarity (positive to positive, negative to negative). If the battery uses a connector, plug it in securely. Use electrical tape to secure any loose wires and prevent short circuits.

Step 6: Reassemble the Speaker

Carefully reattach the speaker casing, ensuring no wires are pinched. Replace and tighten the screws, and verify that the casing is secure. A properly reassembled speaker is essential for the four 40W Seviz battery replacement to be successful.

Step 7: Test the Speaker

Charge the speaker fully using the included Micro USB cable. Power it on and test its functionality, including Bluetooth connectivity, FM radio, and audio playback. Monitor the battery life over a few hours to confirm the four 40W Seviz battery replacement was successful.
