Bosch EXPERT 18V battery vs ProCORE?

The short answer is: both battery types fit your tools. The new EXPERT 18V series works with all blue Bosch Professional 18V power tools and AMPShare alliance devices. You do not need to replace your existing equipment to take advantage of the new batteries.

The choice depends on the tools you use every day. For power-hungry machines such as angle grinders, circular saws, or blowers, choose the EXPERT or ProCORE series. If you mainly work with a standard drill driver or impact driver, a classic GBA battery will be completely sufficient for you.

Differences between EXPERT, ProCORE, and GBA series

The EXPERT 18V series went on sale in September 2025 and includes four capacities: 4.0 Ah (EXBA18V-40), 5.5 Ah (EXBA18V-55), 8.0 Ah (EXBA18V-80), and the powerful 15.0 Ah (EXBA18V-150). The previous ProCORE18V series remains available on the market and enjoys very good user reviews. In the US market, the equivalent of the ProCORE line is the CORE18V series, for example the GBA18V80 model.

The main difference is the maximum power output. The EXBA18V-40 and EXBA18V-55 batteries deliver up to 2000 W of power, while the EXBA18V-80 and EXBA18V-150 models reach up to 2400 W. For comparison, the older GBA 18V 4.0 Ah battery reached 1000 W of maximum power in Bosch testing.

Higher power translates into real runtime under heavy load. In tests conducted by Bosch, the EXBA18V-80 battery lasted up to 120% longer than the GBA 18V 4.0 Ah when grinding steel with the GWS 18V-15 S grinder. In turn, the largest EXBA18V-150 model powering the GBL 18V-750 blower provided a runtime up to 280% longer compared to the GBA 4.0 Ah.

Selected EXPERT batteries feature innovative tabless cells. Bosch states that it is the first manufacturer on the market to use them in 18 V power tool batteries. However, it is worth noting that not all models in this series feature this design. Tabless cells are found in the EXBA18V-40 and EXBA18V-80 models, whereas in the US market, for example, the EXBA18V-60 model is available with traditional 21700 cells arranged in two layers.

The external design has also changed. EXPERT batteries feature a housing with special metal inserts, reinforced power contacts, and an improved CoolPack 2.0 cooling system. The charge level is indicated by five LEDs that support the Defect Risk Detection function.

Fun fact: Bosch states that it is the first manufacturer in the world to introduce tabless cells to 18 V batteries designed to power power tools.

Below we have gathered popular batteries and chargers from the EXPERT, ProCORE, and GBA series to help you assemble the optimal power set for your workshop.

Recommended Bosch 18V batteries and chargers

Chargers for EXPERT batteries: old and new models

You can easily charge the new EXPERT batteries with older Professional 18V system chargers. However, keep in mind that basic models take quite a long time to do so. For example, the popular GAL 18V-40 charger takes as much as 124 minutes to fully charge the EXBA18V-80 battery from zero to one hundred percent.

A good, versatile intermediate choice is the GAL 12V/18V-80 charger. It charges noticeably faster than the 4 A model and also allows you to power smaller 12 V batteries from the Bosch blue line if you use both voltage standards in one workshop.

For demanding users, Bosch has prepared dedicated, ultra-fast chargers: the EXAL18V-160 and the dual-bay EXAL18V2-320. In Power Boost mode, the EXAL18V-160 model delivers a current of up to 16 A and charges the EXBA18V-80 battery to full in 39 minutes, which means a process three times faster than with the GAL 18V-40. The dual-port EXAL18V2-320 version charges two batteries at the same time and is designed to fit directly into the L-Boxx system case.

The new charging stations are equipped with Long Life and Standard modes that protect cell lifespan during daily work. These devices are designed for safe battery charging across a wide ambient temperature range from -10 to +55 degrees Celsius.

Fun fact: The new EXAL18V-160 fast charger charges the EXBA18V-80 battery in just 39 minutes, while the basic GAL 18V-40 charger takes as much as 124 minutes for the same task.

What not to mix: green Bosch POWER FOR ALL

When shopping, you must pay attention to the colors and markings of the tools. Green Bosch power tools and garden equipment belong to the DIY POWER FOR ALL system. It is a completely different battery standard with a different slot and different communication with the charger.

Blue EXPERT, ProCORE18V, and GBA batteries fit all blue power tools from the Bosch Professional 18V line as well as tools affiliated with the multi-brand AMPShare alliance. Under no circumstances will you be able to insert them into green POWER FOR ALL tools or charge them in green chargers.

Frequently Asked Questions

Does the Bosch EXPERT battery fit old Professional 18V tools?

Yes, all batteries from the new EXPERT 18V series are fully backward compatible. You can attach them to any blue power tool from the Bosch 18V professional system. They also work with partner brand tools affiliated with the AMPShare alliance.

What is the difference between Bosch EXPERT and ProCORE?

The EXPERT series is a newer generation of power, offering peak power reaching up to 2400 W compared to older designs. Selected EXPERT models are equipped with tabless cells, reinforced housings with metal inserts, and indicators with failure risk detection. The ProCORE series, known in the USA as CORE18V, is an older, still manufactured, and proven line of high-performance batteries.

Will the GAL 18V-40 charger charge an EXPERT battery?

Yes, the basic GAL 18V-40 charger will charge any battery from the EXPERT series. However, you must remember that the charging process will take quite a long time. For the EXBA18V-80 model, a full charge takes about 124 minutes.

Which charger charges Bosch EXPERT batteries the fastest?

In Power Boost mode, the charging current reaches 16 A, allowing you to recharge the EXBA18V-80 battery in just 39 minutes. These devices can operate safely in temperatures from -10 to +55 degrees Celsius.

Does the Bosch Professional battery fit green Bosch tools?

No, Bosch Professional batteries do not fit green home and garden tools. The green line uses a separate POWER FOR ALL standard with different mechanical and electrical connectors. For blue batteries, you must exclusively use blue Bosch tools or machines from the AMPShare alliance.
