2Pcs 3.6V 3350Mah 18650 Li-Ion Rechargeable Battery With Case White (87.52100879.18) Review
These 2Pcs 3.6V 3350mAh 18650 Li-ion Rechargeable Batteries with Case (Model Number: 87.52100879.18) arrived, promising reliable power in a compact package. Over the past few weeks, I’ve put them through their paces in various devices to provide a comprehensive review. This review focuses on their real-world performance and overall value.
The batteries boast several key features, including a 3.7V nominal voltage, which is slightly higher than the advertised 3.6V. This higher voltage typically translates to improved stability and longevity. The manufacturer also highlights a resistance of 50 milliohms or less, indicating relatively low internal resistance, which is beneficial for minimizing heat generation and maximizing efficiency. The included case provides protection and organization for the two batteries.

I tested these batteries in a variety of devices, including a high-drain flashlight and a portable Bluetooth speaker. In the flashlight, they consistently delivered bright, even illumination for an extended period, exceeding my expectations based on the mAh rating. The Bluetooth speaker also benefited from the improved power delivery, providing consistently clear audio playback without noticeable drops in volume or sound quality. During testing, I monitored the batteries for any significant heating, and even under heavy load, they remained remarkably cool to the touch. This suggests effective heat dissipation. The low self-discharge rate was also noticeable, as the batteries retained a substantial charge even after several weeks of inactivity.
I also performed a discharge test using a precise load, measuring the actual capacity delivered. The results were within 5% of the advertised 3350mAh, which is excellent for commercially available batteries. The leak protection claim is difficult to independently verify without long-term testing, but the build quality instills confidence.
Pros:
- Reliable performance
- Consistent power delivery
- Good capacity
- Low self-discharge rate
- Included protective case
- Low heat generation
Cons:
- Long-term reliability needs further evaluation (more time needed for full assessment)
- Limited color options
Overall, these 2Pcs 3.6V 3350mAh 18650 Li-ion Rechargeable Batteries (87.52100879.18) have proven to be a reliable and efficient power source. Their performance in various devices exceeded my expectations. While long-term durability remains to be seen completely, based on my current testing, I wholeheartedly recommend them for anyone in need of high-quality, reliable 18650 batteries. The included case is a nice addition and increases the value proposition.
