Description

The CZVV 1.5V Rechargeable AA Lithium battery is designed for use in household and business items like mice, keyboards, gamepads, remotes, toys, and more. Ultra-High Capacity High energy density in a small volume ensures maximum capacity.

Cycle 1300s of Times Cycle times to over 1300x, the combined value of a single battery exceeds 1000 ordinary dry batteries. All batteries are guaranteed to be pre-charged before leaving the factory. CZVV warrants these batteries to be free from defects in materials and workmanship. About Constant Output We have noticed that for a long time, there has been a tangled question - why are the advantages of disposable and rechargeable batteries incompatible? The voltage of a rechargeable battery always drops gradually over time. When the rechargeable battery voltage is not high enough to wake the device, a new annoyance arises - why does the rechargeable battery always seem to fail to achieve the ideal battery life? The key to solving this problem is how to keep the voltage of the rechargeable battery at a constant level. A new generation of 1.5V constant voltage output AA rechargeable batteries is here. Equipped with short-circuit protection, overcharge protection, constant voltage control circuit, etc. - the CZVV laboratory has once again defined the smart chip technology in the battery field. About CZVV We are an emerging high-tech enterprise from China. We founded the brand with the vision to redefine green energy and make life better. At CZVV, we focus on producing the highest quality products for consumers - a philosophy that has been in place since we produced our first battery on the shop floor. Since then, the pursuit of supply chain excellence has become not an end but a mission for us. Not the end, but the beginning.

    • great batteries!
Color: White Charger with 8 Batteries
i've now bought 3 8 pack with charger because buying the batteries by themselves is more expensive. But the batteries are awesome! Remote controls have more range, and the batteries last a lot longer than regular duracell or energizer, and being able to recharge them quickly means way less waste.

    • 1 bad out of 8, but getting full 1.5v
Color: White Charger with 8 Batteries
Review Image by Mohammad Zeeshan Mohammad Zeeshan
Review Image by Mohammad Zeeshan Mohammad Zeeshan
I bought these batteries specifically for an outdoor siren, since lithium batteries are known to provide a consistent 1.5v, compared to the 1.2 - 1.3v from Ni-MH, which is what I required for a nice loud siren. From my research both lithium and Ni-MH carry similar capacities/ mAh. I do not know if the Lithium ones also have a very slow discharge rate when not in use like the Eneloops but long story short lithium wins for providing a consistently higher voltage for devices that need it. I put 4 of these after charging in the siren which started acting weirdly. It seemingly connected to the hub but would not produce any sound. I thought the siren had gone bad. Reluctantly I swapped the batteries with the almost dead alkaline ones and it worked. I then put in fully charged Ni-MH ones from EBL which I had bought at the same time as these, and it worked again. I thought these lithium ones probably didn't have enough juice to power the damn thing. Disappointingly, before putting them away, I checked them one by one with a multimeter and sure enough one was completely dead. Putting it back in the charger, the blue/ red lights kept fluctuating for a few sec and then turned off completely as if it is completely charged per instructions. It still was dead. I have since put in 4 working ones of these and the siren is working. It doesn't subjectively sound any louder with the full 1.5v incase anyone was wandering lol. The durability/ reliability and (hopefully slow) discharge rate of these remains to be seen. The charger and batteries do not look cheaply made. Don't know if they come pre-charged fully but they seemingly topped off quickly (<45 min for all 8) on first charge. After buying ~60-70 rechargeable AA/AAA/9V batteries from Eneloop, EBL, Ansmann, Tenergy over the last 10 years with zero dead on arrival and most working up till now, I must say 1 out of 8 (12.5%) DOA rate is not great. I took the chance with a new brand and tech (rechargeable lithium AA), but I guess I'll stick to Eneloops even with the lower voltage, due to their excellent reliability, or will try the non-rechargeable lithium variants. Side note: The way lithium batteries provide a near constant 1.5V until they completely die, might lead many devices to inaccurately display battery percentages. When these batteries need a charge they don't fall down gradually like alkaline and Ni-MH (with the battery percentage reading showing that in most devices) but rather the voltage drops abruptly when they need a charge. So just FYI for devices that are vital/ emergency related, I would suggest vigilance and recharging them periodically without relying too much on the battery indicator. ... show more
