## Overview

The Bosch GBA18V40-2PK is a 2-pack of 18V CORE18V® Lithium-Ion 4 Ah Advanced Power Batteries designed for professional-grade performance. Featuring cutting-edge 21700 cells and Bosch-exclusive CoolPack 2.0 technology, these compact batteries deliver 60% more power and double the runtime of standard 2 Ah packs while weighing only 1.1 lbs each. Compatible with Bosch 18V tools and the AMPShare system, they offer efficient, long-lasting power for medium-duty applications like drilling, grinding, and cutting.

## Description

This 2 Pack features two Bosch CORE18V® 4 Ah Advanced Power Batteries, each of which is a compact battery delivering power in a lightweight solution. It allows you to get the power and lose the weight. The GBA18V40 delivers high power in a compact size for standard to medium-duty applications, such as drilling into concrete, metal and wood; metal grinding; cutting and even light-duty chipping. It delivers 2x the runtime and 60% more power compared to BAT612 18V 2 Ah battery. The GBA18V40 is designed with high-power Lithium-ion cells, featuring a single layer of enhanced 21700 cells for greater battery efficiency. Cutting-edge battery design – includes copper end plates, power rails and a flexible circuit board for reduced resistance and increased efficiency. This Advanced Power Battery has the Bosch-exclusive CoolPack™ 2.0 technology, which cools the battery faster and helps provide longer lifetime compared to Bosch 18V batteries without CoolPack™ 2.0. This compact battery weighs only 1.10 Lbs. but provides performance comparable to much heavier batteries in a lightweight solution. It is compatible with Bosch 18V tools and chargers and the AMPShare™ System. It also has a high-resolution charge-status indicator.

Review: Great Priced Batteries - Not much to say about them, they’re batteries. They were a great price, I get a little over an hour worth of usage out of them on my Bosch cordless sander, and that’s with the 4ah batteries. They do however take a long time to charge which probably has more to do with the charger then the batteries. But I will be ordering another two pack soon. It’s a great deal considering what Lowes is asking for them.
Review: THE BEST Batteries On The Market - I date my batteries when I get them. I am still using 2.0ah Bosch batteries I bought in 2012! One is starting to lose it's longevity after TWELVE YEARS of use! These 4.0 batteries run tools forever, at a slightly higher weight than the basic 2.0ah pack. I grab batteries when they are on special and I just got four of these 4ah batteries to run bigger tools like saws and blowers. I have been a Bosch owner for 20+ years and have 17 tools that have run reliably and taken routine abuse.

### ⭐⭐⭐⭐⭐ Long Lasting
*by T***Y on November 16, 2025*

So far so good. I really love (ok, like) my Bosch battery powered tools and the fact that they are using the same battery platform for so many years, and years to come.
