Having a spare replacement battery enables digital camera users to use all the facilities of their camera without concern of running out of battery power & missing that all important shot. Battery cases are precision moulded using the latest laser techniques & the battery cells are pre-tested for 24 hours before final assembly. Protection & charging PCBs are also designed & produced in-house using the latest SMT machines. Finally, a built-in microprocessor safeguards the cells by limiting maximum voltage & protecting against deep discharge, short circuit & overload. This ensures that the quality of the Inov 8 brand is maintained to a very high standard & is backed by a full two year warranty against manufacturing defects. Most digital camera users are unaware that the CCD (Charged Couple Device) remains charged even though the camera is switched off. This is to enable quick start-up time when the camera is switched on. Therefore if their camera has not been used for a few weeks could find themselves with a greatly reduced battery that potentially lasts just a few shots. If a recently charged low-cost INOV8 replacement battery was amongst their camera kit they could switch batteries & start shooting immediately.
