In addition to the brennenstuhl® professionalLINE rechargeable battery AB 1805 (Art. No. 9834518), all Bosch rechargeable batteries from the GBA 18 V x.x Ah Professional series can also be used. Due to the limited space available because of the battery cover on the LA 4000 / LA 4010 cordless and hybrid lamps, only batteries up to max. 6.0 Ah can be used with these lamps!
The use of the Bosch 18V ProCore series 4, 8 and 12 Ah is not possible with this blaster series due to larger dimensions.
