The Bosch GXS18V-28N115X 18V Starter Kit pairs the ultra-high-capacity EXBA18V-15 EXPERT 15 Ah battery with the EXAL18V-160 16-Amp turbo charger, delivering sustained high-current power and rapid charging for demanding industrial applications. Engineered specifically for high-drain cordless equipment such as large rotary hammers, angle grinders, and stationary jobsite tools, this kit maximizes runtimes under heavy continuous loads without power fade.

The EXBA18V-15 battery incorporates three parallel layers of high-power 21700 lithium-ion cells alongside Bosch COOLPACK 2.0 heat-management housing. This structure minimizes internal electrical resistance and channels heat outward away from core components, preventing premature thermal shutdown and extending overall pack service life under full load.

The EXAL18V-160 turbo charger utilizes Active Air Cooling and provides a maximum charging current of 16 Amps to minimize turnaround intervals. A dedicated mode button enables switching between standard charging, Power Boost mode for rapid battery replenishment, and Long Life mode, which caps charging at 80% capacity to maximize cell longevity.

Features & Benefits

• 15.0 Ah Maximum Capacity: Delivers up to 50% longer runtime and up to 20% more instantaneous maximum power than standard CORE18V 12.0 Ah batteries.
• Triple-Layer 21700 Architecture: Distributes high electrical draw evenly across three layers of large-format cells to sustain high-amp tool performance.
• COOLPACK 2.0 Heat Management: Directs heat away from the cells to prevent thermal cutoffs during continuous operation.
• 16-Amp Turbo Charging Output: Rapidly recharges high-capacity batteries to keep production tools operational on the jobsite.
• Selectable Charging Modes: Push-button selection engages Power Boost for fast turnaround or Long Life mode to limit charge level to 80% for maximum cycle lifespan.
• Active Air Cooling: Draws cool air across battery cells during charging to reduce internal temperatures and cycle times.
• 5-LED Charge Status Gauge: Displays clear battery state-of-charge, remaining capacity, and operational warnings directly on the pack.
• AMPShare System Compatibility: Fully interchangeable across all Bosch Professional 18V tools and multi-brand cordless products within the AMPShare alliance.

Shipping: Beaver Industrial Supply offers free shipping on orders over $199, with the exception of Sawstop and Laguna, which require additional fees to be collected. Other exceptions apply as noted on product pages.

We reserve the right to determine the fastest and most cost-effective manner of transportation for all orders that qualify for free shipping. Our shipping carriers cannot deliver to PO box or U.S. military post office box addresses, such as APO and FPO, so we require a physical street address for delivery.

If the item qualifies for free shipping, you will be charged the original shipping cost and are responsible for shipping the product back with the shipping carrier of your choice.

We must receive the item undamaged. We recommend you package it accordingly and purchase insurance for higher-priced items to ensure you receive the full refund minus any incurred fees as applicable. We reserve the right to refuse the return of accessories.

Because items are your responsibility until they reach us, we recommend that you send the parcel using a delivery service that insures you of the value of the goods. Return shipping is at the customer's cost. At Beaver Industrial Supply’s discretion, delivery charges can be refunded if the goods are defective.

Returns require a return authorization number. Please call customer service at 314-773-5999 or submit a customer service inquiry to start the exchange or return process and receive an authorization number.

Machinery too large for parcel shipment (palletized or crated) is only returnable if there is a material defect that cannot be resolved by replacing components.
