18V 4.0Ah FORCE Tabless Battery (A18OB4T) - see what's inside

The AEG 18V 4.0Ah FORCE TABLESS Battery is engineered to get an improved performance out of your AEG 18V tools. Revolutionary tabless battery technology enables tools to be pushed harder for longer and with less resistance*.

Laser welded cell straps and upgraded heat sinks are also part of the Battery's advanced thermal management system, which reduces the occurrence of over-temping.

Performance upgrades driver greater results from this Battery including 29% faster cutting, 24% faster drilling and 15% faster driving compared to a standard AEG 4.0Ah FORCE Battery (A18FB4).**

*Based on test results performed under lab conditions by Techtronic Industries between 1 March - 30 October 2024. Max output can be sustained for up to 10 seconds. Power applies to battery output. Tool performance may vary.

**Test results performed under lab conditions by Techtronic Industries between 8 January - 15 February 2025 showed the 18V 4.0Ah FORCE TABLESS Battery, used under heavy load applications, generated 29% faster cutting with the 184mm FUSION Circular Saw (A18FCS680), 24% faster drilling with the FUSION Hammer Drill (A18FPD0) and 15% faster driving with the FUSION Impact Driver (A18FID0) when compared to the AEG 18V 4.0Ah FORCE Battery (A18FB4).
