Can You Obtain Watch Battery Samples From Multiple Production Dates?

When evaluating watch batteries for quality consistency, buyers may need samples manufactured at different times. However, the available records for the Vinnic 0% Mercury Silver Oxide Button Cell do not state whether CHUNG PAK can provide samples selected from multiple production dates.

The product documentation covers battery performance, model availability, inspection practices, minimum order quantity, and standard delivery lead time. It does not describe a sample policy, batch-selection process, manufacturing-date range, or procedure for requesting date-specific battery samples. Buyers should therefore confirm this requirement directly with CHUNG PAK before placing a sample or production order.

Watch Battery Product Overview

The product referenced in the supplied information is the Vinnic 0% Mercury Silver Oxide Button Cell, commonly used as a watch battery. It is designed to offer strong leakage resistance, stable voltage output, low self-discharge, and extended operating life.

These characteristics make silver oxide button cells suitable for devices that require dependable and consistent power over time, particularly precision timekeeping equipment.

Supported Applications

The listed applications include mid-range and high-end quartz watches, pocket watches, wall clocks, sports stopwatches, and laboratory precision timers. Product selection should be based on the device's required battery size, electrical specification, and operating conditions.

Availability of Samples by Production Date

No supplied record confirms that samples can be requested from different manufacturing dates. There is also no stated information regarding batch codes, shelf-life verification, production-date labeling, retained stock, or the number of samples available from each production period.

For buyers conducting comparative testing, aging studies, incoming quality checks, or supplier qualification, the request should clearly identify the required battery model, target production dates or date range, sample quantity, and any necessary batch traceability documentation.

Available Silver Oxide Button Cell Models

The listed model range includes 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.

Before requesting date-specific samples, buyers should verify the exact model reference and confirm whether stock from the requested production periods remains available.

Quality Control and Manufacturing Information

The documented quality framework includes 100% inspection during production, laboratory sample testing, and incoming inspection of raw materials. These procedures indicate that quality checks are performed throughout the manufacturing process.

Although these controls support product quality management, they do not by themselves confirm the availability of batteries from separate production dates. Production-date selection remains a commercial and inventory-related matter that requires supplier confirmation.

CHUNG PAK lists ISO 9001:2015 and ISO 14001:2015 certifications. Its battery operation is supported by broader manufacturing capabilities involving paper separators, zinc materials, metal and plastic components, tools, and machinery.
