The Frequent FAQs of Dry-charged Battery
What is a dry-charged battery and how does it differ from a maintenance-free or sealed battery▾
A JUST dry-charged battery is shipped without electrolyte (0% acid), activated on-site; maintenance-free/sealed batteries are factory-filled, permanently sealed, water loss <4 g/Ah, self-discharge ≈3%/month.
What advantages do dry-charged batteries offer in terms of storage life and shelf life before activation▾
JUST dry-charged batteries can be stored up to 24–36 months at 20–25°C with <10% capacity loss, versus 6–12 months for conventional wet-charged, significantly reducing inventory obsolescence.
How is a dry-charged battery activated and what type of electrolyte is required▾
Activate a dry-charged battery by filling cells to level with 1.260–1.280 SG sulfuric acid (H₂SO₄, ~30–36% w/w), rest 20–60 minutes, then charge at C/10–C/20 for 3–10 hours.
