How to Replace Samsung Watch Active 2 40mm Battery (BR830ABY) and Extend Its Lifespan

Introduction

The Samsung Galaxy Watch Active 2 40mm (models R830 and R835) is one of the most popular smartwatches for fitness enthusiasts and tech lovers. With its sleek design, health-tracking features, and smart notifications, it has become an essential part of daily life. However, like any wearable device, the battery is a critical component that determines how long your watch can last on a single charge.

Over time, lithium-ion batteries degrade, causing shorter battery life, unexpected shutdowns, or charging problems. If you are experiencing these issues, replacing the battery with a Genuine BR830ABY (0.92Wh / 240mAh) is the best solution. In this article, we’ll explain everything you need to know about the Samsung Watch Active 2 battery replacement, why the BR830ABY is the right choice, and how to extend the lifespan of your new battery.

Why Replace the Battery in Your Samsung Watch Active 2?

Batteries are consumable parts, meaning they naturally wear out with usage. The Samsung Watch Active 2 battery may start showing signs of degradation after 1–2 years depending on usage patterns. Common issues include:

• Unexpected shutdowns – The device powers off even when the battery shows charge.
• Charging difficulties – The watch fails to charge fully or stops charging suddenly.
• Overheating – The battery gets unusually hot during use or charging.

If you notice these symptoms, it’s time to consider replacing your old battery with the BR830ABY 240mAh battery, which is specifically designed for the 40mm Samsung Watch Active 2 models R830 and R835.
