conclusions
1) store a long time 2/3 led indicator (40-80% charge) or 2/5 for EneRacer/ProCore
2) if the capacity is more than 80%, then 1880 does not charge, but shows a charge of 100%
3) if several times to put off, then charging will begin 80->100% 4) until the fan has shut down, the infection continues, even if the led is already lit continuously
