Another Compatible battery types — dl2450, cr2450n, ecr2450, br2450, kcr2450, 5029lc, lm2450 and etc. This makes them suitable for all types of watches from high drain digital watches to low drain analogue watches. Since sensitive electronics might have issues operating at such low voltage and may have issues with reliability when using alkaline AG4/LR66/LR626 batteries.

To prevent confusion and thanks to modern chemistry and battery technology, some manufacturers offer multi-drain 376/377 batteries (compatible with SR626SW batteries, of course) that feature good tolerance to high-drain pulse currents and low self-discharge rate. For example, if you are looking for a watch battery replacement for your watch, and it was a Maxell SR626SW, you would scroll down the Maxell column until you found the part. mm, which isn't much - however, while battery compartments intended for SR626SW batteries may accept smaller SR621SW batteries, contacts with the SR621SW battery may NOT be fully reliable.If You are unsure regarding low-drain or high-drain models, go for a multi-drain SR626SW battery, also labeled as 367/377 battery. If they get swallowed, these batteries may start electrolytic reactions that may cause chemical burns, which are very dangerous. LR626 (alkaline) or SR626 (silver-oxide) capacities depend on the chemistry, but also on the cut-off voltage of the used device - alkaline batteries' voltage quickly drops, making them not so suitable for electronic devices like wrist watches and similar.

mm (lust as SR621SW battery), and it is generally not compatible with 377 battery with physical dimensions of 6. According to the IEC standard, and depending on their chemistry, these batteries should be labeled LR626 (alkaline) or SR626 (silver-oxide) batteries, and according to the ANSI standard, 1176SO batteries.As one can see, actual performances vary depending on the discharge current and temperature but also depending on the battery age. Although they can be found in small electronic devices including small toys, cameras and calculators, this Duracell D377/376 button cell’s most common application as a watch battery. When you wear a high-quality watch, you want a high-quality watch battery to keep it running reliably; and Energizer is the brand name that immediately springs to mind. Modern LR626/SR626 batteries don't contain mercury, cadmium, and other heavy metals or dangerous toxins.
