Keenstone offers a 3.7V consistent voltage with a 2-hour charge time with over 1000 recharge cycles. Nothing is better than reducing your carbon footprint while saving you money and time.
There are two types of household batteries: non-rechargeable and rechargeable. Non-rechargeable batteries are expensive long-term and rarely eco-friendly. So people look to rechargeable batteries like Ni-MH. However, they still have limitations too like long recharge time, high self-discharge over time, insufficient voltage, and shorter recharge cycles.
Keenstone offers RCR123A rechargeable lithium batteries that are commonly used in household appliances. AA batteries are used for most gadgets such as remotes, toys, shavers, flashlights, keyboards, and much more.
Compared to alkaline and NiMH battery, the Keenstone RCR123A lithium rechargeable batteries provide a consistent 3.7 voltage output regardless of battery capacity. See the illustration below for a direct comparison. As you see, the alkaline battery voltage drops significantly and the NiMH battery is unstable.
In this toy car racing test, we’re comparing Keenstone to the Eneloop Pro to see how it holds up. A remote control race car is one of the most power demanding devices. You’ll see within the first hour, Keenstone reaches 530 cycles, outnumbering the Eneloop by 100 cycles with a more steady lap time due to Keenstone 3.7V output.
In the second test, we put Keenstone and Eneloop pro batteries into two flashlights. As you can see, the easiest way to review the voltage output is reviewing the lightbulbs. The flashlight with Keenstone batteries remains at a stable brightness while the right while the flashlight with Eneloop Pro flickers.
Voltage consistency is what distinct Keenstone from its competitors. Batteries with a consistent voltage output can not only protect the device but optimize the product lifespan, especially for high-drain devices.
Experience fast charging like never before. Within 2 hours, Keenstone can be fully ready. The majority of Ni-MH batteries take 5 or more hours to recharge. Keenstone reduces the waiting time by over 50% to offer you an unmatched charging experience.
The Keenstone’ high recharge cycles is attributed to lithium's weaker memory effect. Keenstone is designed to retain up to 70% of its original capacity at 1000 charge cycles, whereas most other material rechargeable batteries can only hold 50% after 500 charge cycles.
A simple charging case is specially designed for travelers. The 8-pack battery charging case features a micro-USB interface weighing at only 186g. Plug in the Micro-USB cable to your computer or power bank to enjoy an easy, fast and ultra-convenient battery recharge.
The charging status is told by Keenstone’ dual charging indicator system. The green LED on the charger indicates the normal status of Micro-USB cable. The implanted blue light on the bottom of the battery shows the charging status of each battery separately. The light goes off when they’re fully charged.
Keenstone meets the battery restrictions of most airlines and can be carried safely in its crew cabin. Compact and lightweight at only 17.3g for each battery, Keenstone is your best traveling batteries!
This charger case is specially designed for Keenstone currently, other batteries are not applicable.
Keenstone has obtained 6 national and world patents. Of which, the proudest patent has to be its innovative three-in-one controller.
Traditional NiMH batteries do not feature a charge/discharge system. Keenstone integrated a safety chip as a charging progress indicator. Once fully charged, the current automatically stops. The built-in chip also prevents charging in abnormal situations, such as a short circuit or extreme temperatures to guarantee safe use.
Keenstone values safety. The battery has undergone rigorous smash and drop testings in the lab. The batteries have been crushed by a pressure of 13 kN (1.3 TONS) or dropped on by a 20kg steel block from a distance of 60cm to test whether leakage or explosivity.
Packed with innovative patented technology and built with eco-friendly materials, Keenstone lithium rechargeable batteries are definitely one-of-a-kind.
Since 2013, six chemical and electronic engineers from Keenstone’s R&D department began to explore new possibilities regarding rechargeable lithium batteries. This paved the way of Keenstone’s development.
During the four-year product development process, engineers have tested more than 20 types of lithium battery chemical systems and over 30 electronic solutions to optimize product performance. Keenstone was then designed with the best product solution for stability and safety.
Under the continuous technological improvement, Keenstone has obtained 6 national invention patents and is currently applying for 3 international patents in United States, Europe, and Japan.
