Whether samples of watch batteries from different manufacturing dates can be supplied is not confirmed in the available product documentation. The records identify the item as the Vinnic 0% Mercury Silver Oxide Button Cell and describe its performance, inspection procedures, minimum order quantity, and delivery schedule. However, they do not define a sample policy or allow customers to select production dates. This request should therefore be verified with CHUNG PAK before ordering.
The supplied technical information focuses on battery performance and intended use rather than production-batch traceability. It mentions resistance to leakage, a consistent voltage output, low self-discharge, and long service duration. No specific manufacturing dates, lot numbers, shelf-life details, or procedures for selecting samples by date are included.
The listed silver oxide button cell references cover models such as 357, 386, 389, 391, 380, 399, 370, 393, 382, 396, 361, 376, 363, 319, 379, V303, V301, V344, V390, V394, V395, 371, V377, V393, V384, V397, V362, V364, V319, V379, SR1154SW, SR1142SW, SR1130SW, SR1120SW, SR936SW, SR927SW, SR920SW, SR921SW, SR754SW, SR736SW, SR726SW, SR721SW, SR626SW, SR621SW, SR527SW, SR63SW, SR64SW, SR60SW, SR66SW, SR69SW, SR57SW, SR716, and SR920SW.
CHUNG PAK states that its quality system includes complete inspection on the production line, laboratory sampling and testing, and inspection of incoming raw materials. These measures demonstrate a structured quality-control process, but they do not confirm that customers may request samples representing different manufacturing dates.
The company lists ISO 9001:2015 and ISO 14001:2015 certifications. Its broader manufacturing operation also covers paper separators, zinc materials, metal and plastic components, tools, and machinery, in addition to battery production.

| End uses | Quartz watches, pocket watches, wall clocks, stopwatches, and laboratory precision timers |
The current records do not provide a definite answer. Since no date-based sample request procedure is described, customers should confirm availability, acceptable date ranges, and quantities directly with CHUNG PAK.
The documentation refers to the Vinnic 0% Mercury Silver Oxide Button Cell range. Examples of the listed references include SR626SW, SR621SW, SR920SW, V303, V377, and several other silver oxide button cell models.
The stated controls consist of full inspection during production, laboratory sampling and testing, and checks on raw materials received by the factory.
At present, the ability to obtain watch battery samples from different production dates remains unverified. To receive a useful confirmation, provide the supplier with the exact battery model, requested manufacturing dates or date range, sample quantity, and any required batch or lot identification. The documented commercial conditions include a minimum order of 10,000 batteries and an estimated delivery time of 30 days. For product assistance or technical support, contact vinnic@chungpak.com.
