The Frequent FAQs of Maintenance-free Battery
What is a maintenance-free battery and how does it differ from a conventional lead-acid battery▾
A maintenance‑free (sealed, Ca‑Ca) battery needs no water topping, has lower self‑discharge (~3%/month vs ~5%), reduced gassing, longer life, but offers slightly less electrolyte access for testing than conventional flooded types.
What is the typical lifespan of a maintenance-free battery under normal operating conditions▾
Under normal use (25°C, regular driving, proper charging), JUST maintenance-free batteries typically last 3–5 years, equating to roughly 500–800 full charge–discharge cycles.
What are the main applications or equipment types suitable for your maintenance-free batteries▾
JUST maintenance‑free batteries suit UPS (0.6–200kVA), telecom base stations (48V systems), solar storage (12V/24V/48V banks), emergency lighting, security, and medical backup requiring 5–12‑year design life.
