only come in increments of 1.5 volts how ever the voulume to engey racial of sla is prety high and u can release it pretty quick take7.2 ah 12 volt and u can pull a 30 amp short a 200 ah 12 vilt sla will start a car and that is what u will find in a wheelchair

how ever it is possable to make a battery out of a bottle of diet rite and with out saying how it could be used as a bomb just by containing an internal short circuit and containing the resulting sodium build up from the high salt content but u could still take a bottle of diet rite on board just not a bottle of deit rite configured as a bomb

the amount of electrical power from a diet rite battery would be less than a aa battery
