Bosch CORE18V 18V 6.3 Ah Battery

Bosch Announces CORE18V GBA18V63 18V 6.3 Ah Battery

Las Vegas, Nev., January 17, 2017 – The Bosch CORE18V Battery offers maximum power and performance while minimizing weight, an achievement that proves its claim as the best-built battery among leading competitors. The battery employs advanced Lithium-ion technology to deliver 80 percent more power than previous generation Bosch batteries. Next-generation, high-powered Bosch CORE18V cells are laser-welded and rail-connected for high efficiency, allowing CORE18V batteries to deliver better performance than competitive batteries that have up to 24 percent more weight and are up to 35 percent larger.

The Bosch CORE18V Battery offers optimized cell technology and an improved power connector within the 10 high-density cells that ensure lower internal resistance. That means higher currents can be drawn from the cells over a longer period of time.


Greater Performance, More Runtime

Bosch has answered the need for stronger and longer-lasting battery performance in high-load applications, where cordless tools have previously been unable to provide enough power and runtime. The Bosch CORE18V Battery delivers up to 20 percent longer runtime than previous-generation Bosch 6.0 Ah batteries and up to 50 percent longer than 5.0 Ah cells in extreme applications.2 Thanks to its next-generation cell technology and power efficiency, the CORE18V battery can generate more current to finish jobs that other batteries can’t. In addition, it’s the most compact and lightweight high-power battery available.

“Bosch looks at battery power from the user perspective. What do users want? They want greater power and more runtime in a compact size, which is what CORE18V is all about,” said Theron Sherrod, product manager, Robert Bosch Tool Corporation. “CORE18V represents a big piece of the Bosch effort to build end-to-end product systems that offer superior performance, no matter what the job is. Based on increased power and runtime, plus backward compatibility across the full power tool lineup, we feel this is a step beyond battery power systems that are currently available.”

The battery housing of Bosch CORE18V is designed to transfer more heat to the outer surface, resulting in up to 35 percent better cooling effect than previous CoolPack batteries. The CoolPack 2.0 system employs advanced design to keep the battery cooler for better runtime and longer life; updated CoolPack technology provides up to 135 percent longer battery life than batteries that don’t have CoolPack technology.

In addition, this technology combined with reduced resistance and higher efficiency means that the battery is less likely to overheat during high-load applications.

Bosch CORE18V batteries provide 100 percent compatibility with all 18-volt Bosch Lithium-ion tools and chargers. Bosch is developing high-power tools to take full advantage of CORE battery technology.

    Really, it delivers 80 percent more power than their previous generation battery? It sound to me that you’re either completely clueless about the relatively simple concept of how batteries actually work and/or easily fooled into believing anything you hear or, maybe, you’re just willing to day anything and everything if the money is good enough, in which case I can only imagine how truthful the rest of your reviews were, a thought I want to get rid of as soon as possible because I actually really like your blog and reviews,in general, minus this one of course.
    Seriously, all bosch did is switch to a larger cell design, which does have the ability to provide a bit more power and store a little more energy but the tradeoff of the larger cells is a larger, heavier battery pack, this is why bosch removed whatever metal it could and switched to a higher quality plastic to make sure the battery doesn’t fall apart the first time a drill flies off a ladder and onto the floor… The welcome side effect of this experiment is a reduced weight and (probably) same durability, thanks to the higher quality non-metallic components.

    But 80 percent more power? Not unless bosch somehow figured out a way to mass-produce graphene, which I know is not possible as of yet. I think that someone might have played a joke on you or that you might be the newest victim of the Fine Print Man.

      Oleg – It’s a press release written by Bosch….we print their press releases like we do for all the tool companies. Also, Bosch doesn’t buy advertising from us so your accusation is off base. You can easily tell what articles are press releases and our reviews, because we put “REVIEW” in the title and we show the product in images from our job sites.
