The charge algorithm of the SLA differs from the NiCd and NiMH in that voltage-limit rather than current-limit is used. The charge time of the SLA is a slow 16 hours. With higher charge currents and multistage charge methods, the charge time can be reduced to 10 hours and less. In no way can the SLA be charged as quickly as the NiCd. A multistage charger applies three charge stages consisting of constant-current charge, topping charge and float charge (see figure below).
Best Answer: Zanaflex will stay in your body at a maximum of 24 hours. I would say that after 3 days of not taking Zanaflex, if your blood was drawn, no trace of Zanaflex would be found. If you look at the package insert [information that the FDA approves and has to be with every medication], on the first page, second column there is a graph. It shows that after 1 dose, at 24 hours, there should be little or no Zanaflex in the bloodstream. Zanaflex also has a pretty short half life (~2 hours) so the graph matches.
