Used primarily in wrist watches, the Maxell 337 Coin Cell Battery is surprisingly powerful for its size, providing 1.55 Volts of current and storing 8.3 mAh of charge. The battery's Silver Oxide chemistry gives it a very high energy density as well as a slow and steady discharge rate, perfect for low energy devices like watches, calculators, film cameras, remote switches and much more. The battery features Maxell's original leak-resistant processing, which prevents the electrolytes of the battery from unintentionally leaking, a natural tendency of alkaline electrolytes.
