Perform Shallow Discharges; Avoid Frequent Full Discharges. Old NiMH and NiCd batteries had a âmemory effectâ and had to be completely discharged from 100% to 0% to keep their capacity. Modern devices use Lithium Ion batteries, which work differently and have no memory effect. In fact, completely discharging a Li-ion battery is bad for it. You should try to perform shallow discharges â discharge the battery to something like 40-70% before recharging it, for example.
Defense Switched Network. The Defense Switched Network (DSN) is a primary information transfer network for the Defense Information Systems Network (DISN).
To call within the DSN system, just dial the 7-digit number. To call a commercial number from a DSN line, first dial '99'. To call a DSN number from a commercial or cellular phone, dial 0505 + 7-digit number (NOTE: This will only work when calling Army installations). Do NOT accept collect calls on a DSN line.
