## Description

czvvRechargeable 9V Batteries - High-Performance Lithium-ion Battery 4 Pack with 4-Bay Speed Charger - Leak-Proof Ultra Long-Lasting 8.7 Volt 1300x Cycle Times with a 10-Year Shelf Life

## Features

- 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.
- ≤4H Strong Fast-Charge: Support 4-channels of fast charging at the same time. Preset with 3 charging models - Trickle charging, Constant Current charging, and Constant voltage charging, 5V 2A input ensures batteries to 100%. LED lights on the charger allow you to check the charging status anytime. 6-in-1 IC chip with a leak-proof design, safety protection comes first, and hassle-free use. *Unauthorized use of other brand chargers may cause accidents.
- 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), CZVV Q019 Pro Individual Portable 4-Bay Charger(Input 5V 2.0A), Type-C Lightning Cable, User Guide, our worry-free 12-month warranty, and friendly customer service
