Sometimes a powerful battery is really needed – and that's what RCR123A /16340 is. With a huge capacity of 650 mAh you can rely on it. With an energy output of 3.7 V, it is also suitable for powering powerful LED lights or other devices that require high voltage. But you can also count on a very low self-discharging rate – this will keep you from charging the battery, and once you want to use it, there will be nothing to take the energy from.
There is no doubt that this battery is very powerful. But what about the security aspect? The battery is protected by PCB (protective circuit board) and has several other safety features such a built-in over charge and discharge protection.
