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 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B09R4B24WK | | Amperage | 2 Amps | | Antenna Location | Radio | | Battery Capacity | 850 Milliamp Hours | | Battery Cell Type | Lithium Polymer | | Battery Weight | 1.16 Ounces | | Best Sellers Rank | #167,379 in Health & Household ( See Top 100 in Health & Household ) #113 in 9V Batteries | | Brand | czvv | | Customer Reviews | 4.5 4.5 out of 5 stars (229) | | External Testing Certification | CE, RoHS, UN38.3, PSE, WEEE, SP188 | | Item Dimensions | 1.8 x 0.66 x 1.04 inches | | Item Weight | 251.2 Grams | | Manufacturer | CZVV | | Model Name | K007J 1*4 + Q019 | | Model Number | K007J 1*4 + Q019 | | Number of Batteries | 5 9V batteries required.
