The invention is about a box for automobile accumulator batteries that function in the surroundings at extreme temperatures, ranging from -30 DEG C to +90 DEG C. According to this invention, the box consists of two frameworks (1, 2), one superposed upon the other, between which there is a space (a) filled with a thermo-insulating layer made of polyurethane foam. Made up of two plane elements (3, 4), between which the polyurethane foam is introduced, the lid (B) has several holes (b) in which filler caps are screwed up (6). The invention proves useful due to the following advantages: it eliminates the thermal shocks of the automobile accumulators - the thermal shocks of which significantly reduce their safety during exploitation; it eliminates the frequent recharging during the wintertime; it gives easiness of exploitation. |
