With a full charge voltage of 8.4V-8.7V and a maximum output current of 2.3A, these batteries are designed for longer-lasting performance. Additionally, they are three times more durable than alkaline batteries and five times longer-lasting than carbon batteries.

Multi-Protection and Safety

Kratax rechargeable batteries are certified to meet rigorous standards such as ROHS, CE, CQC, and PSE. They are equipped with advanced protection features to prevent overcharge, overvoltage, overcurrent, overdischarge, reverse charging, and short-circuiting. This ensures reliable performance and longevity for both the batteries and chargers.

Wide Compatibility

Suitable for a wide range of electronic devices including wireless microphones, multimeters, electric guitars, walkie-talkies, toy remote controls, smoke alarms, cameras, massagers, alarm clocks, portable radios, and transistor radios, these batteries offer versatile and reliable power solutions.

Independent Charging Channels

Designed with one independent charging channel, each battery can be charged individually via a 5V 2A USB input, eliminating the need to charge them in pairs. Using a USB Type-C cable, you can fully charge 1 battery in about 3.7 hours or up to 4 batteries within the same time frame. The IC-controlled charging process ensures constant voltage, eliminating the memory effect and minimizing potential damage to the battery. This makes for a longer cycle life and higher capacity.

Environmentally Friendly

Our batteries are free from toxic and harmful heavy metals like lead, mercury, and cadmium. They have a low self-discharge rate of just 0.03% per month, which is 1/100th of Ni-MH batteries. Additionally, the weight of these batteries is 30% less than Ni-MH batteries, making them a more eco-friendly and lightweight choice.

In summary, the Kratax 9V lithium battery provides high capacity, multi-protection, wide compatibility, independent charging, and eco-friendly features, making it an ideal choice for any electronic device.
