The battery holder is provided with L-shaped holders each having the form of a first plate and a second plate connected at a right angle corner and having an L-shaped lateral cross-section, and flat-plate holders that connect with the L-shaped holders and have an overall planar form. The L-shaped holder has connecting holes on the outside of the corner between the first plate and second plate. Further, the outer edge of the first plate opposite the corner is provided with first connecting tabs that can connect with connecting holes of another L-shaped holder. The flat-plate holder is provided with second connecting tabs on at least one side edge that connect with connecting holes of an L-shaped holder.
