How long does battery last using EX-1 Mars continuously?
A. For EX-1 Mars, it depends on what type of battery you use. In dry cells, alkaline batteries last longer with better conditions. Normal dry cell batteries can be obtained cheaper but you should be careful with longer usage. Nicad battery is economical and reasonably long lasting. However, with either type of battery, it should last 1 to 2 hours. (nicad batteries can vary depending on the method of charging.) Things to avoid are installing pen cell type nicad batteries into dry cell battery holder. Nicad battery produces gas while charging and discharging ant it could rust and as a result create a bad connection between terminals and cause sudden malfunction (cut off). Therefore use genuine KO nicad pack which has spot type welding for each cell connection.
