    A: The frequency of testing depends on various factors such as battery type, usage, and operating conditions. As a general guideline, it’s recommended to test the specific gravity at regular intervals (e.g., every 1-3 months) or whenever you notice a significant change in battery performance.

    Q: Can a battery hydrometer measure the state of charge of a sealed lead-acid (SLA) battery?
    A: Unfortunately, battery hydrometers cannot measure the state of charge of sealed lead-acid batteries, as their electrolyte is sealed within the battery. For SLA batteries, it’s best to rely on voltage measurements using a multimeter or a charger with an integrated state-of-charge indicator.
