Needed a small lithium cell that wouldn't fail after a few months in a wearable device, basically anything below 200mAh in a form factor this thin tends to heat up or lose capacty fast, but this one's holding steady according to early bench tests we ran. So I ordered the AS501235 with the 160mAh rating — not the biggest capacity, but the cycle life is specified at over 500 cycles, which is better than most cheap pouch cells in this size range, give or take. We've had trouble before with cells that bulk-ordered under CE marks turning out to be counterfeit, so the UL plus IEC62133 certification here is actually worth paying for.
Charge votage tops out at 4.23V, but the nominal rate is 4.2V obviously — most buyers go with the standard 32mA (0.2C) for routine charging, though the fast charge rate at 160mA is useful if your device cycles quickly and you can tolerate higher heat buildup. And the cut-off discharge at 3.0V is a bit tighter than other 3.7V cells we've seen, which means the BMS needs to catch voltage drop early or you risk hitting under-voltage and getting false dead-battery readings. Dimensions come out to roughly 5.2 x 13 x 37.5mm with the tiny PCB attached — that's a little longer than bare cell (by maybe 1.5mm), so account for that in your housing clearance.
What it isn't suited for is high-drain devices like camera flashes or small motors, peak discharge is capped at 160mA (1.0C) for continuous draw, so one instance someone pumped it into a mini haptic driver and got voltage sag that killed uptime in minutes. We usually have stock on these form the same production lot, but confirm lead time if you're pushing past 500 units — MOQ is decent at 100 pieces, but incremental pricing drops a few cents at 500 or so. One concrete handling oddity: the thin aluminum laminate pouch is surprisingly easy to puncture if you use tweezers near the edge, a problem I've never seen with earlier models that had thicker tabs.
Temperature tolerance is decent for this class — charge works from 0°C up to 45°C, discharge dips to -10°C; storage below 35°C for three months keeps self-discharge negligible, about 3-5% loss per month at room temp in my experience. The 160mAh capacity is nominal (rating at 0.2C discharge), and you'll get roughly 85-90% of that at the 1C rate, which is consistent with LiPo chemistry specs. They do ship with a one-year warranty, and each pallet comes with a CoA that includes HPLC data, though the real test is consistency across batches — we've had two sample packs test within 4mAh of each other, so the QC seems solid so far.
Also, fast-charge to 90% capacity reportedly takes under 10 minutes according to marketing, but from what we saw on the waveform this is heavily dependent on initial OCV — if your applicaion pulls the cell to near 3.2V before charging, the 160mA aggressive ramp can trigger OVP cutoff early. Anyway, the form factor works well for low-profile wearables, and the weight at 3.5g is low enough you won't notice it in a wristband. The packaging is standard anti-static trays of 20 cells each, individually sealed in foil bags with desiccant — one detail most spec sheets skip is that the tacky residue from the PSA sticker on the bag will stick to your gloves if you handle them in a cleanroom.
Our MOQ for this model is typically 1,000 pieces, but we can discuss smaller trial orders if you're just getting started. Just let us know your volume and we'll see what we can do.
Standard lead time is around 15-20 working days for bulk orders, depending on the quantity. We can expedite for rush orders, so just reach out with your timeline.
Yes, absolutely. We include copies of our CE, UL, RoHS, Reach, IEC62133, and UN38.3 certifications with every bulk order. Just request them when placing the order.
Store them in a cool, dry place between -10°C and +35°C for up to 3 months, or up to 45°C for short-term storage. Keep them at around 30-50% charge for best long-term performance.
Yes, we can customize the PCB protection board or add a specific connector to fit your design. Minimum customization order is usually 2,000 pieces, but let us know your specs and we'll quote.
