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.

DSC is a paging system that uses data signals to automate the transmission and reception of calls on VHF marine radio channel 70. Every DSC radio has a unique number, which you use to call other radios, just like a mobile phone.However, unlike mobile phones, DSC allows you to call every other radio in range at the same time if you are in trouble.SC also offers the ability to send and receive GPS positions-all DSC radios can be connected to a GPS receiver. A DSC message is a brief burst of digitised information transmitted from one station to alert another station or stations.
