Max. fluid temperature
The maximum fluid temperature that the sprayer can safely handle.
The preparation process of some formulations requires heating; therefore, data on the temperature to which the liquid must cool can be very important for safe operation. However, even in the most heat-resistant sprayers, this figure does not exceed 40 °C; such a liquid feels warm to the touch.
It is worth remembering the temperature limits when the unit is in the sun: if the tank has had time to get very hot in the sun, you should let it cool down before starting work.
Capacity
Capacity of the complete battery in the battery sprayer (see "Type").
A higher capacity allows you to work longer without recharging, but this is true only “ceteris paribus” — the actual energy consumption (and therefore battery life) depends on the performance, range and some other characteristics of the sprayer. Therefore, only devices with similar indicators can be compared by this parameter, and it is easier to evaluate battery life by directly claimed operating time (see below). Also, larger batteries tend to weigh more and cost more. Therefore, manufacturers usually choose the battery capacity according to the features of a particular model — in order, on the one hand, to ensure good battery life, and on the other hand, not to greatly increase the weight and price.
Operating time
Time of continuous operation of the battery sprayer (see "Type") on one battery charge. The actual operating time may differ slightly from the claimed one due to the specifics of a particular situation, however, these differences are usually not very large, and this indicator can be used to evaluate not only theoretical, but also practical indicators of battery life.
Weight
The total weight of the sprayer. Specified without taking into account the liquid or powder in the working tank; at the same time, for battery models (see “Type”), usually, the weight is given with a complete battery, and for gasoline models, on the contrary, “dry” weight, without fuel in the tank.
