Please note:

• This transparent casing version of the battery requires regular inspection of the electrolyte level and timely addition of qualified distilled water (if needed).

• Adding electrolyte should be strictly in accordance with the manufacturer's instructions to avoid safety hazards or damage to the battery due to improper operation.

Differences from the non-transparent casing version:

• This version features a transparent casing for easy viewing of the battery's internal condition and checking the electrolyte level.

• This version is more suitable for applications that require frequent electrolyte level checks.

• The non-transparent casing version may be slightly less expensive, but requires other methods (such as voltage measurement) to determine the electrolyte level.
