4. Configuració i instal·lació
This battery pack is designed for self-installation, meaning you will replace the internal cells of an existing battery housing. This process requires careful attention to detail and basic technical skills. If you are not comfortable with this procedure, please seek professional assistance.
Eines necessàries:
- Screwdriver set (to open battery housing)
- Soldering iron and solder (for connecting cells, if required by your specific pack design)
- Talladors/pellaferros
- Heat shrink tubing or electrical tape (for insulation)
- Multimeter (optional, for checking voltage i polaritat)
- Guants i ulleres de seguretat
Passos d'instal·lació:
- Preparar l'espai de treball: Ensure your workspace is clean, well-lit, and free of conductive materials. Wear safety glasses and gloves.
- Disassemble Old Battery Pack: Obriu amb cura la casing of your old battery pack. Note the arrangement and connections of the existing cells. Take photos if necessary for reference.
- Remove Old Cells: Desolder or disconnect the old battery cells. Be careful not to damage the battery management system (BMS) or other electronic components, if present.
- Arrange New Cells: Arrange the new Seilylanka Ni-MH cells in the same configuration as the old cells. Ensure correct polarity (+ and - terminals) as per the original pack's design.
- Connect New Cells: Solder the new cells into place, replicating the original connections. Ensure strong, clean solder joints. Insulate all exposed connections with heat shrink tubing or electrical tape to prevent short circuits.
- Test Connections (Optional but Recommended): Use a multimeter to check the total voltage of the assembled pack before closing the housing. It should be approximately 18V (or slightly less if cells are not fully charged). Verify there are no short circuits.
- Reassemble Battery Pack: Carefully close the battery housing, ensuring all wires are properly routed and not pinched. Secure the housing with screws.
- Càrrec inicial: Place the newly assembled battery pack into a compatible Ni-MH charger and perform a full charge cycle before first use.

5. Instruccions de funcionament
Once installed, your Seilylanka Ni-MH battery pack operates like any standard Ni-MH battery for your power tool.
Càrrega:
- Use only chargers specifically designed for 18V Ni-MH battery packs. Using an incompatible charger (e.g., Ni-Cd or Li-ion charger) can damage the battery and pose a safety risk.
- Carregueu la bateria en una zona ben ventilada, allunyada de materials inflamables.
- Allow the battery to cool down before charging if it has just been used intensively.
- Do not overcharge. Most modern Ni-MH chargers have automatic shut-off features.
Ús:
- Insert the battery pack firmly into your compatible power tool until it clicks into place.
- Operate the tool as per its own instruction manual.
- Avoid completely draining the battery (deep discharge) frequently, as this can reduce its lifespan. Ni-MH batteries benefit from being recharged before they are fully depleted.
- If the tool's performance significantly drops, it's time to recharge the battery.
6. Manteniment
Proper maintenance extends the life and performance of your battery pack.
