Factory Supply 12V Gel Type Lead Acid Battery for Solar Street Lights and Medical Equipment

It basically pulls consistent current for longer discharge windows than most standard AGMs—we’ve run these on solar street light arrays pulling about 8A nightly for two years with no drop-off at the controller. The gel electrolyte is what does it, keeping the plates form sulfating even when you’re cycling down to 50% depth of discharge every day.

150AH at the 20-hour rate is the number to look at, which gives you roughly 7.5A continuous for 20 hours before you hit the cutoff. At 12V nominal that’s about 1.8kWh usable if you’re not hammering past 50% DOD, which we don’t recommend anyway. Cycle life sits at 500+ cycles when you stay in that range. Self-discharge is under 3% per month, so you can bench it for a couple months without top charging.

We’ve seen these going into medical carts pretty often—mobile ultrasound units and those infusion pump setups where you need a steady 12V bus and can’t have acid sloshing. ABS case holds up fine at -15°C but don’t push past 50°C without derating the capasity about 10-15% base on what we’ve measured. 44kg is heavy (roughly 97lb), so the T5/F7 terminals are sized for heavier 35mm² cable lugs without stress on the posts.

Actually, the silica gel isn’t all the same across suppilers, we use European silica in ours—it wets out the plates more uniformly, which shows in the capacity test results when you check the first cycle COA. The separator material is something we improved last year after getting feedback about vibration issues in solar street pole mounts. We usually stock these, but lead time for OEM bulk orders (200 units or so) is typically 20 days give or take.

MOQ is 10 units for standard packaging—strapped on a pallet, no individual cartons, which saves freight space. If you’re pairing these with a charge controller that pulls peak over 120A, you’ll want to oversize to two in parallel rather than run one at max discharge current. it have CE, ISO9001, and ISO14001, but request the specific COA for the batch if you need the internal resistnce value under 3.5 mΩ.

People sometimes try to use these for engine-starting appliction. Don’t. The internal impedance is too high for cranking amps—this is strictly deep cycle. For solar street lights running on PWM controllers, the battery lasts longer than most buyers initially expect, usually hitting that 500-cycle mark without the bulging you see on cheaper gel knockoffs.
