What it basically does in practice is give you a relaible buffer for solar or wind setups where the sun isn't always shining—the carbon in the negative plate helps it handle partial charging way better than a standard lead-acid, so you're not constantly worrying about sulfation when the weather's patchy.
It's 300Ah at the 20-hour rate, which is a solid workhorse number for off-grid storage, and you can push it up to 1500A for five seconds if you need a surge for starting a pump or something—the internal resistance sits at about 1.10 milliohms when fully charged, so it's pretty efficient at delivering that burst.
Cycle life is over 2000 cycles at 80% depth of discharge, and design life is quoted at 20 years at 25°C, but we usually see them hold up well past that in temperate climates—the gel electrolyte helps with that longevity, and it's fire-resistant ABS plastic case, which matters for indoor installs.
Where it really fits is in large-scale storage banks for commerical or community solar projects, or for anyone doing a multi-string setup where you need 2V cells to hit higher voltages like 48V or 96V—it's not ideal for small portable kits or anything you're moving around, it's heavy at about 16.3kg per cell.
For ordering, we ship to the US and EU regularly, and our company have the CE, IEC, and ISO certifications ready for customs clearance—teh OEM/ODM service is available if you need your own branding, but we usually stock the standard HC2-300 with a lead time of 20 days or so (check with me for current stock levels).
One detail a lot of buyers don't think to ask about is that the self-discharge is under 3% per month at 25°C, so it sits on a shelf for a few weeks without needing a top-up charge—that's better than many flooded batteries we've handled, and it means less maintenance on system overall.
We can work with a small trial order—no hard MOQ for initial samples. Just let us know how many you need and we'll quote accordingly.
For a 100-unit order, lead time is usually 15-20 working days after deposit. If stock is available, we can ship within a week.
Yes, we include CE and IEC certification copies with every shipment. ISO documents are also available upon request.
Store them in a cool, dry place below 25°C, and recharge every 6 months to keep self-discharge under 3% per month.
Yes, we offer OEM/ODM service. Just send us your terminal or connector specs, and we can adjust the battery accordingly.
