Your modern 9 V block batteries: They fully replace standard block batteries and deliver an enormous 4,500 mWh of energy - for radio, toy remote control and more.
High-performance rechargeable batteries: Thanks to constantly high power output and particularly low self-discharge, the rechargeable batteries are perfectly suited for e.g. smoke detectors and measuring instruments.
Charging without battery charger: Unlike conventional rechargeable batteries, you can simply charge them via USB, e.g. with the power adapter of your mobile device. Clever: The included USB charging cable charges both batteries at the same time if required!
