With the rise of scenarios such as outdoor camping and small family gatherings, portable Bluetooth speakers have become popular products in the consumer electronics market due to their ability to provide high - quality sound and easy portability. A portable Bluetooth speaker launched by an audio equipment brand takes "long battery life + high sound quality + splash proof" as its core selling points and needs to solve the problems of short battery life (only 6 - 8 hours on a single charge) of traditional speakers and unstable power supply (leading to sound distortion) when playing at high volume.
In the battery selection stage, the brand tested a variety of 3.7V lithium batteries and finally determined that the BAKTH - 606394 - 1S - 3 battery was the optimal solution.
In terms of battery life, the large 4800mAh capacity allows the speaker to play continuously for 18 hours at medium volume (60% volume, suitable for outdoor leisure scenarios) and 10 hours at high volume (100% volume, family gathering scenarios), which is more than 50% higher than the battery life of traditional speakers. The stable 3.7V voltage provides a continuous and balanced current for the speaker's audio amplification module. Even when playing bass tracks at high volume, there is no current noise or sound distortion, ensuring the sound quality.
The thin design of the BAKTH - 606394 - 1S - 3 battery (complying with the 606394 size specification) enables the speaker to maintain a compact appearance, making it easy for users to hold or put in a backpack. After the speaker was launched, it was widely praised by consumers for its ultra - long battery life and stable sound quality. In the user reviews on e - commerce platforms, the proportion of feedback such as "battery life exceeds expectations" and "continuous playback for a day without charging" accounts for more than 70%, and the stable performance of the BAKTH - 606394 - 1S - 3 battery has become one of the core competitiveness of the product.
