New Bosch battery range for professionals. Expert 18V: Maximum power, longer runtime

The Expert 18V high-performance batteries set new standards – with up to 2,400 watts of maximum power¹ and up to 280 percent² longer runtime compared to the GBA 18V 4.0 Ah Professional battery. The range for trade professionals is part of Bosch’s top performance class Expert. It comprises four rechargeable batteries with capacities of 4.0, 5.5, 8.0 and 15.0 ampere hours as well as two high-speed chargers. The Expert 18V batteries and chargers are compatible with the Professional 18V System and the multi-brand AmpShare battery alliance.

Power on a new level

The Expert 18V batteries take power to the next level. The EXBA18V-40 and EXBA18V-55 achieve maximum powers of up to 2,000 watts.¹ Compared to current batteries in the Bosch range, such as the GBA 18V 4.0 Ah Professional, the temporary maximum power has been doubled. The EXBA18V-80 and EXBA18V-150 even deliver up to 2,400 watts of temporary maximum power1. This makes all batteries in the Expert range ideal for particularly demanding applications.

Long, uninterrupted work thanks to an even longer runtime

The new Expert 18V rechargeable batteries also set new standards in terms of runtime. Compared to the GBA 18V 4.0 Ah Professional, the EXBA18V-80 extends the runtime by up to 120 percent.² The rechargeable battery in the new range with the largest capacity is the EXBA18V-150 with 15.0 Ah. The high-performance battery offers a runtime that exceeds that of the GBA 18V 4.0 Ah Professional by up to 280 percent.²

Innovative tabless technology for maximum efficiency

Bosch has become the world’s first manufacturer to bring the benefits of tabless technology in battery cells to 18V batteries for cordless power tools. Both, EXBA18V-40 and EXBA18V-80 also feature tabless cells. In conventional lithium-ion batteries, cells have small connection bands on both sides – so called “tabs”. They create a bottleneck for the power delivered by the battery and contribute to the cell’s electrical inner resistance, causing heat to be generated. To ensure that the battery doesn’t overheat, particularly during high-performance applications, the tool shuts itself off, leaving the remaining energy in the battery unused. Using tabless cells, this bottleneck has been eliminated and the current flows via countless parallel paths. The result: Less resistance, less heat, and longer runtime for high-performance applications.

More robust than ever before

The newly designed housing has been specially developed for challenging use on construction sites. Metal inserts and a reinforced contact system make the new Expert 18V rechargeable batteries extremely robust. The CoolPack 2.0 technology also enables rapid heat dissipation. This combination allows users to benefit from a particularly long battery lifetime. At the same time, the new release button and use of Soft-Grip ensure ergonomic handling. There are five LEDs on the back of the battery that indicate either the state of charge or, with the new Defect Risk Detection, possible risks.

Ultra-fast charging – even under extreme conditions

The new Expert chargers also contribute to greater efficiency on construction sites. They are also compatible with the Professional 18V System rechargeable batteries from Bosch and the AmpShare Alliance. The compact EXAL18V-160 single charger fully charges an EXBA18V-80 rechargeable battery within 39 minutes in Power Boost mode with up to 16 amperes of charging current, making it three times faster than the GAL 18V-40 Professional³ charger. The EXAL18V2-320 dual charger fully charges two of these rechargeable batteries at the same time. For more gentle charging, professionals can select two additional modes via a button on the charger: The Long Life mode ensures maximum battery life, while Standard mode balances charging power and battery life. Active Air Cooling cools the rechargeable batteries and Flex-Temp Charging extends the battery charging temperature range of the Expert rechargeable batteries from -10°C to +55°C. Both functions therefore minimize the downtime of the batteries by enabling a quick charging start, whether after demanding applications or in cold temperatures.

The EXAL18V2-320 dual charger is the first charger from Bosch that has been fully optimized for use, transport, and storage in a specially developed L-Boxx. The mobile charging station has space for the charger and a total of four rechargeable batteries.

The Expert 18V batteries and chargers will be available individually and in practical sets from September 2025. All prices are recommended retail prices and do not include VAT.
