    Product arrived in a well done blister with english label and instructions. Battery box seems solid and durable. Battery is already charged at 9.38V. No evaluation about capacity and affidability for now. Maybe in the future, if possible a new review. A good rate price/quality.

    j'ai acheter un petit pack de deux piles.... je voulais tester dans mes détecteurs de fumée afin de ne plus avoir a payer une blinde pour ce type de pile, de plus en rechargement, cela devrait etre un peu plus utile et ne pas gaspiller des métaux précieux dans des piles conventionnelles.. Bref, plus qu'a tester sur l'année qui arrive.

    Неплохие аккумуляторы для устройств с небольшим энергопотреблением. Область применения ограничена из-за особенностей конструкции. Плюсы: 1. Зарядка от USB. Не нужно отдельное зарядное. 2. Стабильное напряжение 9V. Критично для некоторых устройств. Минусы: 1. Повышенный саморазряд. Нужно заряжать раз в 3 месяца, даже если не используется. 2. Нет никакой возможности контролировать оставшийся заряд. Будьте готовы к тому, что ваше устройство может отключиться в любой момент, резко и без предупреждения.

    Very well designed, manufactured and finished. An interesting development in charging rechargable batteries.

    These are convenient to use for powering meters and other electronic projects. I will use these to power a portable oscilloscope. Delivery was good and the price was great. Good value. Thanks Banggood.

    Werken goed opladen werkt ook. Handig is da je voor deze batterijen gewoon je gsm oplader kan gebruiken. Want aparte laders kan je kwijtgeraken en da zou zonde van het geld zijn

    This battery has a 9.55 volt unloaded, and 9.4 volt loaded voltage, so acts like a brand new 9 volt battery. It requires 900 mAh at 5 volt to fully charge, that is 4.5 Wh. If you discharge it with 0.4 A, then you can take out 2.82 Wh at 9.5 volt, that is about 300 mAh. I consider those good values. When short cicuit protection kicks in, voltage drops to 1.8 volt. Charge it for 1 second, then it will come back to normal voltage.
