- Higher Capacity, Lower Spend: Upgraded 850mAh Lithium cobalt oxide battery with about 2.6x larger capacity than common 9V 320mAh batteries. The eco-friendly concept runs through manufacturing. Say NO to harmful substances together such as Hg/Cd/Pd. Less than 1% – self-discharge rate of CZVV 9v li-ion rechargeable battery ensures 85% capacity maintenance after 36 months of non-use. Longer 1300x service life – The Energy is About to Shift – a wonderful combination of electricity and chemistry.
- Wide Applications: Compatible with most 9V battery-powered devices, like 9-volt smoke sensors, garage door openers, alarm clocks, wireless microphones, radios, electronic toys, flashlights, remote controls, massagers, transceivers, guitars, bass guitars, metal detectors, multi-function instruments, etc.
- Why 8.7V instead of 9V? – As we all know, the nominal voltage of a Li-ion battery is 3.7V, and the full-charged voltage is 4.2V – better known as the charge cut-off voltage. By connecting two groups of 3.8V High-Energy-Density lithium-polymer cells in series, we fabricated K007 with an EnergyCLSave frame. Under ideal conditions, a fully charged 9-volt battery will maintain a high voltage of about 8.7V(4.35V*2) – the highest voltage among all brands’ Lithium-ion 9V batteries can achieve so far.
- What You Get: CZVV Ultra 850mAh 9V Batteries(4 Count Pack with Output DC 8.7V), our worry-free 12-month warranty, and friendly customer service
