Questions about this item

How do I install the 131.50 x 22.00 x 20.10 mm battery in my Sony SRS-X7, and what step is often missed?

Open the speaker compartment, align the connector with the LIS2181HNPD part number, and press firmly until it clicks; the step often missed is fully seating the connector before closing the cover.

What maintenance will the 2600mAh lithium-ion pack need later?

After 2 or 3 full charge and discharge cycles the pack reaches peak capacity; store it below 60 °C and avoid low-quality chargers to maximise lifespan.

What limit appears first during extended playback at high volume?

The 7.4 V 19.24 Wh capacity determines runtime; sustained high output will drain the 2600 mAh cells until the protection circuit shuts the pack down.
