Bosch Expert Starter Set - 2x EXBA18V-40 18V 4.0Ah Batteries and GAL 12V/18V-80 Charger

Runtime depends heavily on the tool and application. However, the 4.0Ah capacity is designed for extended use on moderately to heavily demanding tasks, providing significantly longer runtime than smaller capacity batteries.

The charger is compatible with all Bosch Professional 12V and 18V batteries, including many older models within those voltage classes. Always check your specific battery model's compatibility.

Tabless cell technology reduces internal resistance within the battery. This leads to less heat generation, improved power delivery (higher wattage), and greater energy density, allowing the battery to perform better and last longer on a charge.

AMPShare is an alliance of leading tool manufacturers. Batteries within the AMPShare Alliance are cross-compatible with tools from participating brands, allowing for greater flexibility in your tool ecosystem.

Lithium-Ion batteries are best maintained when not stored fully discharged or fully charged for extended periods. It's generally recommended to charge them when capacity is low and to avoid leaving them on the charger indefinitely after completion.

Bosch Professional tools and batteries typically come with a standard warranty. Please refer to the official Bosch Professional warranty documentation for the most accurate and up-to-date information, which often includes an option for extended warranty registration.

Ensure the battery is correctly seated in the charger. Check that the charger is plugged into a working power outlet. Clean the battery and charger contacts with a dry cloth. Try a different compatible battery in the charger, or try the battery in a different compatible charger.

Ensure the battery is fully charged and properly inserted into the tool. Check for any debris in the battery or tool connection points and clean if necessary. Try a different fully charged battery to confirm if the issue is with the battery or the tool.

Batteries naturally degrade over time and with use. Ensure the battery is not being stored in extreme temperatures. For consistent high-power tools, consider upgrading to a higher capacity battery if available or ensuring optimal charging practices.

Refer to the charger's manual for specific error code meanings related to the flashing LED pattern. This may indicate an issue with the battery, charger, or power supply.
