Dobrý den, po zapnutí UPS pouze svítí dioda Ecomode, podle mně by měla blikat, jakože se nabíjí baterka. Při výpadku proudu nesvítí dioda BattMode, ale rovnou začne blikat dioda LowBatt a po pár vteřinách se proud úplně přeruší. UPS tedy neplní vůbec svojí roli. Co to znamená? Je blbý akumulátor? Jak to zjistit? Děkuji.
