AEG PRO18V replacement batteries

About this battery system

AEG's PRO18V family uses 18V lithium-ion slide packs. The range includes compact packs for lighter jobs and larger multi-row packs for sustained drilling, cutting and grinding. AEG's charger documentation identifies five-cell 2Ah packs and ten-cell 4–6Ah packs; these are cell counts, not a universal promise about every revision.

AEG PRO18V should not be assumed interchangeable with Milwaukee M18 despite the shared 18V label.

Manufacturer-supported example specifications below; individual tool fitments and Amazon availability still require checking.

Battery chemistry, cells and energy

AEG's A18DPC manual lists 5 Li-ion cells in L1820R 2Ah and 5 × 2 cells in L1840R/L1850R 4–5Ah packs. Cell format (18650 or 21700) is not established for all models.

Energy (Wh) = nominal voltage (V) × capacity (Ah). Divide by 1,000 for kWh. These are nominal estimates, not measured usable energy or guaranteed runtime. A 90Wh pack is 0.09kWh; at an illustrative constant 90W load, ideal runtime would be one hour before losses. Real power tools draw variable power.

Choosing a replacement battery

Platform family is an initial research grouping, not a verified fitment for every tool or generation. Check exact tool model, battery part number, connector and charger compatibility. Do not assume matching voltage means interchangeable.
