    Very good batteries, they are light and with high capacity. They are quick and easy to load. They have a LED charge level indicator.

    Good product. Replace the multimeter alkaline battery with very good results. I also installed it in my house alarm.

    Пульсации 90мВ. Но это на холостом ходу. Под нагрузкой 120 Ом (около 80мА) амплитуда пульсаций снижается раза в четыре. Частота преобразователя увеличивается до 500кГц. Подключил к аккумулятору нагрузку. Вольтметр подключаю параллельно. На свежезаряженном аккумуляторе при нагрузке

    These batteries is not good. Charging is working, bat... Max. current have limit only 100mA. The electronic of battery not allow higher current. Capacity of batteries is too lower than 800mA. First battery have 249 mAh, second battery have 284 mAh. Screens of the tests are enclosed. I am afraid, bat I do not recomend these items.

    I tested these batteries at 135 mA, which I suspect is a much higher current than designed. i used a FX-35 load bank, a INA219 current sensor, a SD card adapter and an Arduino Nano V3. All of this can be purchased from Banggood. I also tested a Harbor Freight 9V alkaline battery for comparison. The results showed that the HF battery lasted longer but also had a lower voltage. I don't know what current the capacity rating of 800 mAh is determined, so don't draw conclusions from the data regarding

    pile rechargeable au format 9V de la marque OKCELL . bonne qualité, déjà deux cycle de charge sans souci. je les utilise pour de l’arrosage automatique. se recharge grâce à une connexion usb sous la pile ... pratique et Economique. je recommande. merci Banggood

    A ver lo que dura, pero de momento, contento con estas baterías de 9V. Cargan a 450 mAh más o menos. De voltaje y corriente, son los correctos anunciados. Compra recomendada!.

    Хорошие батареи. Ёмкость соответствует. Есть индикатор заряда надо нажать кнопку сбоку. Зарядка по USB.

    Il prodotto sembra ottimo e leggerissimo, si carica molto piu velocemente di una NichelMetal e la tensione a pieno carico e' di 9,2 Volt non resta che vedere come si conportera' nel tempo. Gli 800mah dichiarati dovrebbero garantire un buon tempo di utilizzo rispetto alle vecchie Nichel. Le consiglio.

    La batteria sembra tutta a posto, si carica velocemente e ha tre led per indicare lo sato di carica. C'è però un grosso problema: le istruzioni sono solo in cinese. The battery seems all right, The charging time is short and has three leds to indicate the charge status. But there is a big problem: the instructions are only in Chinese.
