How to open the SPK325-BK speaker to replace the battery?
Frequently Asked Questions - 20/06/2026
Response Notice-Facile

To open the casing of your Manta SPK325-BK speaker and access the battery, you first need to locate and remove all the fixing screws. Carefully check the casing, as some screws may be hidden under labels, plastic covers, or in areas close to connectors and ports. Count about 12 screws distributed around the casing.

Once the screws are removed, gently insert a non-abrasive tool (such as a plastic spatula or a thin rubber lever) into the junction between the two shells of the casing. Start at an angle or a corner, then apply a light constant pressure all around to gradually loosen the assembly joint. This methodical approach avoids forcing the casing and damaging it.

After breaking the initial seal, you should be able to gradually separate the two shells with your hands. Proceed with caution during this separation: a connection ribbon or an internal linking cable usually connects the two parts of the casing. Before completely separating them, gently disconnect this internal connector to avoid tearing it.

The battery is generally positioned near the connection ribbon, often at the bottom of the casing. It is held in place by a connector (plug) or sometimes glued. Note the position of the battery connector before removing it, to facilitate the reinstallation of the new battery in the same orientation.

When reassembling, first insert the new battery connector into its slot, then reposition the shells by properly aligning all internal elements (ribbons, cables). Reconnect the internal linking connector, realign the two shells, and reinsert all screws in the same order. Tighten firmly but without forcing, avoiding jerky movements that could damage the plastic structure.
