A customer pulls a plow truck out of a ditch at -25°C in January, and what it does is crank that big V8 hard enough to get it running when the block heater wasn't plugged in — that's the kind of situation this 6-QTF-92 is built for, not some garage queen that sits on a trickle charger all winter.
850 cold cranking amps is the number that matters most here, and it holds that rating at -18°C with about 2.8mΩ internal resistance, so voltage drop stays manageable even when the starter's dragging against frozen oil, and usually 92Ah at the 20-hour rate is enough for a dual-battery setup in an overland rig or a backup sump pump system that runs for eight hours on float charge.
We've seen these go into commercail refrigerated trucks where they're under constant vibration and partial state-of-charge cycling, and the calcium-lead alloy grids seem to handle that better than standard antimony types, though we don't have hard data on cycle life at 50% DoD — figure 400 cycles or so if you're pushing it deep, but for starting duty it's basically fit-and-forget for 3-5 years typically.
We ship these on pallets of 12 units (the master carton pretty much fits standard freight dimensions) with the terminals protected by plastic caps and a COA from ISO9001 line, though the RoHS and CE marks are more for paperwork compliance than anything you'll feel in performnce — check TDS for storage if you're sitting on inventory, because self-discharge runs about 8% per month at 20°C, so plan rotation if you're buying a year's worth at once.
These use a constant voltage charge profile at 13.8V (actually 14.4V for equalization if needed) which is standard for automotive alternators, so drop-in replacement on a vehicle is straightforward, but the 27kg weight means you're not going to want to carry one up three flights of stairs — get a dolly or have two people for handling, and the PP case is tough but not indestructible if you drop it on a sharp corner.
Anyway, 2-year manufacturing defects but not overcharging or phyiscal damage, and the MOQ is usually 4 units if ordering direct, though we've got a few pallets in stock right now so lead time is 10-15 working days unless it's peak season — for large volume we'd suggest checking stock position before placing a PO.
We require a minimum order of 50 units for the 6-QTF-92. If you need fewer, let us know—we can sometimes accommodate sample orders for first-time buyers.
Standard lead time is 15-20 working days after order confirmation and deposit. For urgent orders, we can expedite to 10-12 days, but that depends on current production load.
Yes, we include ISO9001, RoHS, and CE certificates with every shipment. We can also share the test report for the 850A CCA and 92Ah capacity if your quality team needs it.
We offer standard automotive terminals as listed, but custom terminal types are possible for orders of 200+ units. Case color is always black polypropylene—we don't change that per order.
Store them in a cool, dry place between -15°C and 40°C. Since the self-discharge rate is 8% per month at 20°C, you'll need to recharge every 6 months to keep them healthy and avoid sulfation.
