Tips for Extending Battery Life

One important tip to extend the life of your batteries is to store them properly. Keep them in a cool, dry place away from direct sunlight or extreme temperatures. This can help prevent leakage and maintain their performance over time.

Another way to prolong battery life is by removing them from devices when not in use. If you won’t be using the device for an extended period, take out the batteries to prevent draining and potential corrosion.

It’s also beneficial to avoid mixing old and new batteries in the same device. Using batteries with different levels of charge can cause uneven power distribution, leading to faster depletion.

Regularly cleaning battery contacts with a soft cloth can improve connectivity and ensure optimal performance. Dirty contacts may create resistance and reduce efficiency, impacting battery life.

Consider investing in rechargeable batteries for devices that undergo frequent use. Rechargeables are more cost-effective and environmentally friendly alternatives that can be reused multiple times before needing replacement.


Understanding battery sizes and equivalents can help you find the right replacement for your AG4 battery. By knowing the features and uses of different batteries like the SR626SW, 377, V377, or D377, you can make informed decisions when it comes to watch battery replacements. Remember to check the voltage and dimensions (6.8 x 2.6) to ensure compatibility with your device. Additionally, implementing tips for extending battery life can save you time and money in the long run. Stay powered up with the right equivalent battery for your needs!
