What is the correct procedure for filling a BS BATTERY conventional dry battery with electrolyte?

[OAutumn]

Filling a BS BATTERY conventional dry battery with electrolyte correctly is crucial for optimal performance. Follow these steps for a safe and effective fill:

1. Preparation for Filling:

   • If your battery has sealing and vent plugs, remove them just before adding electrolyte.
   • If a long exhaust tube is present, cut off its sealed end approximately 3cm (1 inch) from the lip. If there's a short sealing tube, replace it with a long one and trim it to the same length as the original.

2. Filling with Electrolyte:

   • Carefully fill the battery with electrolyte (diluted sulphuric acid) that has a density of 1,280.
   • Add electrolyte until it reaches the "upper level" marking on the battery casing.
   • Ensure the electrolyte temperature does not surpass 30°C (86°F) during the filling process.
   • Allow the battery to sit for about 30 minutes after filling. The electrolyte level may drop, so top it up to the "upper level" if needed. Adhering to these steps ensures your BS BATTERY conventional dry battery is filled correctly, promoting its longevity and efficiency.
