User manual PROFOTO PRO-7 B CHARGERS

[. . . ] Battery facts About battery lifetime and how to prolong it The Pro-7b generator is equipped with one of the best long-life batteries with special characteristics to support very short recycling times. This battery type does not suffer from so-called memory effects known from old cellular phones. In fact, the battery is negatively affected by complete discharge and recharge cycles. [. . . ] · The life is doubled if less than 50% of the batteries capacity is used before recharge. · If only 25% of the batteries capacity is used before recharge, the lifetime increases 8 times, i. e. make sure to charge the battery as often as you can. · Only use Profoto three-step chargers. Factors that will shorten battery life: · The battery is left fully discharged for long periods. · Usage of non-Profoto chargers. Pro-7b Chargers & Battery facts At what temperatures can the Pro-7b be used, charged and stored? Ord. no. 10 40 26 The Pro-7b generator can be used when the temperature of the battery is within the range of -20º to +40ºC (-4º to +104ºF) The capacity of the battery decreases dramatically when the battery temperature falls below freezing (+32ºF) The generator and battery have a great thermal mass which will maintain the operational temperature for a long time, especially when insulated. It is therefore advisable to use the Pro-7b Protective Case (or similar insulating case) to keep the generator warm when used at low temperatures. Please note- because of this heavy mass, it can take several hours for a cold battery to restore operational temperature. · It is advisable to have the generator set to slow recharging when the battery temperature is low. · Never charge the battery if the battery temperature is below zero (+32ºF) or above +40ºC (+104ºF) · Do not store the unit in hot or cold conditions prior to use. · The battery itself must have the right temperature, it is not sufficient that the surrounding temperature is within the correct range, · Do not to expose the generator to direct sunlight and/or extremely high temperatures for longer periods than one hour. · Keep the Pro-7b protected from snow, rain, moisture and dirt.
