Setup: Battery Activation (Filling with Electrolyte)
Your Yuasa YTX9-BS battery is supplied dry and requires activation by filling it with the provided electrolyte. Follow these steps carefully:
- Bereiden: Place the battery on a horizontal, stable surface. Ensure you are wearing appropriate safety gear (gloves, eye protection).
- Remove Seal: Carefully remove the sealed foil label from the top of the battery.
- Prepare Electrolyte Pack: Remove the black cap from the electrolyte pack. Keep this cap, as it will be used to seal the battery later. Caution: Do not poke or remove the foil seals from the electrolyte pack (liquid pack).
- Fill Battery: Align the electrolyte pack with the 6 cells (tubes) of the battery. Upside down the electrolyte pack and gently push it into the 6 cells of the battery. The electrolyte will start to flow into the cells.
- Monitor Filling: While filling, make sure at least one tube has bubbles from both sides (each side has 3 tubes). It may take 20-25 minutes to fill all the electrolyte pack. Caution: Do not remove the electrolyte pack until it's fully filled. If no bubbles on both sides of tubes, gently tap the pack from the bottom 2 to 3 times.
- Seal Battery: Once fully filled, gently remove the electrolyte pack from the top. Seal the 6 cells of the battery by pushing the black cap (from Step 3) all the way in. Ensure the cap is sealed flatly on the lid. After capping the battery, do not remove the cap and fill any water or electrolyte anymore.
- Initiële kosten: You will need to charge the battery after all the processes above. Refer to the "Charging" section for details.
