Decrease Quantity of JCB Multipack Assorted Sizes LR44 LR41 LR43 Watch Battery 357 AG1 364 AG3 392 AG4 377 AG12 AG13.Since sensitive electronics might have issues operating at such low voltage and may have issues with reliability when using alkaline AG4/LR66/LR626 batteries.
These batteries are commonly found in wrist watches, calculators, and similar small electronic devices requiring a reliable power source. Generally speaking, the 376 battery is a non-rechargeable silver-oxide high-drain battery, while the 377 battery is a non-rechargeable silver-oxide low-drain battery.Another Compatible battery types — dl2450, cr2450n, ecr2450, br2450, kcr2450, 5029lc, lm2450 and etc. mm batteries - they differ in size, capacity, and other important features making them anything but compatible. Note that some silver oxide SR626 batteries are designed as high-drain batteries and are more suitable for digital watches and similar electronic devices, while other SR626 batteries are designed as low-drain batteries and are more suitable for analog watches, digital watches without alarms and LEDs, thermometers, and similar.
