NONE BETTER
Coupled with a Metz 45 unit, I've gotten as many as 650 flashes at f5:6 using ISO 400 with film or digital. Battery never got below 1/4 charge. Been using this unit for over 20 years- it does NOT fail. Ever!
The Quantum Battery 2 provides hundreds of full power flashes and fast, consistent recycling for many 9 volt flash units.
Uses modules specially designed to fit into the flash battery compartment to replace unpredictable nicads or alkalines.50% faster recycling, and consistently fast even as battery charge is depleted.250+ full power manual shots, and 1000+ automatic shots per charge.
