We're looking at the 19000mAh D-cell here, ER34615, and it's a lithium thionyl chloride chemistry that's been our go-to for utility meters for years — basically non-rechargeable, but you already know that.
You'll see these in alarm systems, GPS trackers, and medical equiment backup where low-current draw over a decade matters more than burst output; it's not suited for high-drain devices like power tools.
Nominal voltage sits at 3.6V with a continuous discharge of 200mA or 400mA pulse, and we've had customers push it to -55°C without issues; the 10-year shelf life (check lead time for fresh stock) comes from self-discharge under 1% per year, which is tighter than most off-the-shelf cells.
We ship form Guangdong with CE, RoHS, GOST-R, and UN38.3 — COAs are standdard, and we'll OEM logo or packaing if you need; MOQ is typically 500 units or so, but confirm for your volume.
One thing we've learned handling these: the aluminun metal jacket holds up better in outdoor enclosures than PVC, but either works fine for indoor meters; anyway, pulse capability matters more for the initial wake-up signal than continuous draw.
Payment terms are usually 30% deposit with 70% before shipment, and we keep about 20,000 units in stock for utility sector buyers, so lead time is roughly 2-4 weeks unless the order is custom.
Continuous discharge is 200mA, but it can handle pulses up to 400mA. Just keep in mind this is a non-rechargeable cell, so heavy drains will reduce overall capacity.
Yes, we do. You can customize the logo, color, packaging, and even add wires or pins. Just let us know your specs when you place the order.
It's CE, RoHS, GOST-R, IEC Reach, and UN38.3 certified. We can send the cert copies along with the shipment or upon request.
MOQ is usually 1000 pieces, but we can work with smaller trial orders. Lead time is around 15-20 days after order confirmation, depending on quantity and customization.
Yes, it's designed for a 10-year shelf life. Store it in a cool, dry place below 30°C, and avoid direct sunlight or moisture. No special handling needed beyond that.
