We’ve been supplying the alumnum-jacket LR6 AM3 for critical devices where votage drop matters, and it consistently hits that 400-minute discharge window under normal load—that's usually enough for continuous patient monitoring across a shift or two.
Basically, your setup with thermometers and sphygmomanometers is exactly where we see most buyers focus, though it also runs well in lab timers and dosing pumps; anything requiring a steady 1.5V without the memory effect of NiMH.
Shelf life hits ten years, and we’ve tested stock pulled from 2020 that still met ≥80% capacity after 12 months at room temp, so you’re safe even if reorders sit for a quarter or so—just confirm lead time because we sometimes hit a 20-day run on the custom blister card packaging.
Weight is 23 grams per cell, give or take, dimensions are standard AA (14.5×50.5mm), and jacket materail isn’t just for looks—it actually reduces risk of leakage in high-humidity sterilization environments that some better-than-reagent-grade cells can’t handle.
What it does is avoid the internal resistance spikes that cheaper Zn/MnO2 chemistries show under continuous load, and you’ll notice that in a sphygmomanometer where a dead battery mid-reading is more than an inconvenience.
our company can OEM your logo or stick with PKCELL, packing is shrink or blister (or we’ve done custom trays for automated feeding lines), but the MOQ on full custom labeling is 10,000 units—and it's pretty much standard that we ship with a current batch COA emailed same day.
Our MOQ for custom packaging and OEM branding typically starts at 10,000 pieces, but we can adjust if you need a larger volume. Just let us know your quantity and we'll confirm.
For a standard bulk order, lead time is about 15-20 days after sample approval and deposit. Rush orders can be expedited if we have stock, but custom packaging adds a few days.
Yes, we include all three certificates—CE, RoHS, and MSDS—with every bulk shipment. They're standard for our medical instrument batteries, so you'll get a copy for your records.
The aluminum jacket is standard for this model to ensure durability and performance, but we can discuss alternatives if you have a specific need. For medical instruments, we recommend sticking with it for best results.
We offer shrink pack, blister card, and fully customized packaging with your logo or design. Mixing different packaging types in one order is possible, but it may affect the lead time slightly.
