For solar storage or medical backup, the OPzV2-1000 handles deep cycling pretty well—we've shipped these to off-grid sites and hospitals alike, and the 1000Ah at the 10hr rate gives you solid runtime for critical loads.
It's a 2V cell, so you'll need to series them up for 12V or 48V systems, but the gel electrolyte means no acid spills and it'll sit at -30°C without freezing up—actually handles 60°C too, though you'll lose some life at the high end.
The internal resistnce is about 0.37mΩ, which is tighter than most flooded options, and with 2500A max discharge for 5 seconds it can handle motor starts or inverter surges without issue.
You'll get roughly 15-20 years out of it in float service, but if you're cycling it daily expect closer to 10-12 years—that's just physics with lead-acid, no way around it.
Lead purity is 99.9997% (we test every batch, COA included), and ABS case is fire-rated, so it passes most medical equipement inspections without extra hassle.
Lead time is usually 30 days or so for a full pallet (we ship them strapped on wood skids), and our company can do custom terminals if you need them—just confirm teh MOQ when you're ready.
Our MOQ for this model is 10 units per order. For larger quantities or ongoing contracts, we can discuss volume discounts and lead time adjustments.
Standard lead time is 25-30 working days after order confirmation and deposit. For rush orders, we can expedite to 15-20 days with a small fee.
Yes, we include CE, IEC, and ISO9001 certificates with every shipment. You can also request test reports for specific parameters like capacity or internal resistance.
Absolutely, the terminals are customizable. Common options include copper or brass inserts, threaded posts, or flat connectors. Just let us know your preferred type, and we'll match it for free.
Store it in a cool, dry place between -20°C and 40°C, away from direct sunlight. With a self-discharge rate under 3% per month at 25°C, it can sit for up to 6 months before needing a recharge.
