Frequently Asked Questions

What is a primary lithium battery?

A primary lithium battery is a single-use cell. It is not rechargeable. It is chosen where a device must run for years without a battery change, where access for replacement is difficult, or where long storage before first use matters. Pkcell's lines include LiSOCl2 (3.6V), LiMnO2 (3V and 9V), lithium button cells (3V CR series), LiFeS2 (1.5V), custom primary lithium battery packs and hybrid pulse capacitor packs.

What is the minimum order?

Minimum order value is USD $500, according to the company FAQ. That figure is an order-value threshold, not a unit price and not a per-model quantity. Per-model minimum quantities are confirmed per order, because the company's published pages do not give per-model MOQ figures.

Are samples available?

Yes. The company states that samples are available. Sample lead time is confirmed per order, because the company's About page and FAQ page give different sample and order lead-time ranges. This site reports lead time as confirmed per order rather than selecting one range as a promise.

What certifications are available?

Certification names differ by product line. The LiSOCl2, LiMnO2 and LiFeS2 lines list KC, UL, MSDS, CB, UN38.3, PSE and More. The battery pack and hybrid pulse capacitor lines list UL, UN38.3, IEC62133, RoHS, MSDS, CE and ISO9001. Certificates are available upon request. Certificate numbers, issuing bodies and validity periods are not published on this site.

What payment and shipping options are stated?

Payment options stated in the company FAQ are T/T, L/C and PayPal. Shipping options stated there are air freight (including FEDEX, DHL, UPS and EMS) or sea freight. Trade terms stated there are EXW, FCA, FOB, CFR and DDU. These are company statements about available options, not guarantees for any single order.

What warranty is stated?

The company states a warranty of 1 to 3 years, without splitting that range by product line. Warranty terms for a specific order are confirmed at the time of ordering.

Do you sell LiFePO4 batteries, lead-acid batteries, Ni-MH batteries or chargers?

Those lines do not appear in the company's own online product catalogue for primary lithium batteries, so this site does not list them as current products. Whether they are current products, and their specifications, are items to be confirmed with the company directly.

How should I confirm a specification before ordering?

Confirm the final datasheet before mass production. That note appears in the source button-cell table and is good practice for every line: capacity variants, operating temperature, discharge conditions and pack structure should all be confirmed against the datasheet for the exact model and order.
