No. However, the batteries are user replaceable and provide enough energy for many uses.
Each cartridge can only be fired once but can deliver multiple electrical cycles. That means that while the darts can only be projected at a target once, as long as the darts remain in the target after the initial 30-second electrical cycle, subsequent electrical cycles can be engaged.
No. Civilians may only purchase 15-foot cartridges. Only Law Enforcement agencies can buy cartridges of other lengths.
All TASER energy weapons are equipped with back-up stun gun features to be used after the cartridge has been deployed.
As long as all conditions for NMI are met (including probe connection and probe spread), a current can flow through muscles and the attacker can lose control of said muscles.
The darts can penetrate clothing and the electricity can also jump up to two inches of combined distances between the probes and the skin.
A TASER energy weapon may work just as well on a 300-pound man as they will on a 150-pound woman.
As probe connection and probe spread are the primary conditions for NMI, a probe deployment's ability to induce NMI does not depend on the target's mental state.
