    Des batteries 18650 d'un bon rapport qualité prix / 18650 batteries with a good price-quality ratio
    Arrivées rapidement, dommage que l'embalage ne soit pas plus résistant, en effet certains étaient abimés au cours du transport, heureusement pas les batteries 18650.

    Arrived quickly, a pity that the packaging is not more resistant, indeed some were damaged during transport, fortunately not the batteries 18650.

    cheap not high capacity
    Cheap batteries, that is nice.
    After receiving these batteries I did a charge and discharge test with an engineering charging device.
    The batteries were rated at 2400mAh, but after two tests the real capacity was around 1500mAh.
    They work but their capacity is lower than expected.

    UltraFire 2PCS 18650 2400mAh 3.7V Li-ion Rechargeable Battery
    Всё пришло в целости и сохранности. По прибытию АКБ были в полузаряженном состоянии, как по сути и должно быть по технологии хранения и транспортировки. Зарядились в соответствии с ёмкостью. Теперь для качественной и долгой работы надо полных 4-6 циклов сделать зарядки/разрядки. Только тогда можно будет судить о их 100% качестве. В чём, в принципе я не сомневаюсь.
    Новые показали, при использовании в светильнике, вызывают моргание светодиодных ламп. Буду пробовать в шуруповёрте.

    Аккумуляторы наполовину заряжены.

    Долгая доставка. С момента оплаты до получения - 50 дней

    Batterie 18650 d'excellente qualité
    ces batteries sont au nom de la célèbre marque ultrafire qui les utilises mais le format 18650 est très standard et peut servir ailleurs comme dans un talkie walkie ou un powerbank USB. vu le prix, super produit
