The BOSCH BAT411 10.8V/12V 3000mAh Li-ion Battery excels in powering tools like the BAT412A, BAT413A, and D-70745GOP models. Its lithium-ion technology offers higher energy density, longer lifespan (500+ charge cycles), and faster charging (45-60 minutes) compared to Ni-Cd alternatives. The EVE Battery cells ensure stable voltage output for demanding applications like drilling and screwdriving.
Which Tools Are Compatible With the BOSCH BAT411 Battery?
This battery powers Bosch’s 10.8V/12V Max system tools including PS20-2 drills, GOP 250 CE jigsaws, and IXO cordless screwdrivers. It’s backward-compatible with older BAT411A/BAT413A models through the SlidePack 10.8 interface. Third-party compatibility extends to Metabo and Fein tools using compatible voltage ranges (9.6V-12V). Always verify terminal alignment before cross-brand use.
Professional users will appreciate the BAT411’s cross-platform versatility. For woodworking applications, it seamlessly integrates with Bosch’s GSR 12V-EC screwdrivers and GDR 12V impact drivers. Metalworkers can pair it with the GBP 12V grinder for up to 35 minutes of continuous cutting. The battery’s compact design (98x67x85mm) makes it ideal for confined spaces when used with telescopic inspection cameras or right-angle drills.

How Does Voltage Affect Performance in Cordless Tools?
The BAT411 operates at nominal 10.8V (12V Max under load), delivering 3000mAh capacity. This translates to 32.4Wh energy storage – 18% more than standard 2.0Ah batteries. Voltage stability maintains 90% torque output until 10% charge remains. High-drain applications like hole saw drilling consume ≈15Wh/minute, providing ≈2 minutes continuous heavy use per full charge.
What Safety Features Protect the BAT411 From Damage?
Bosch’s Electronic Cell Protection (ECP) system monitors temperature (-20°C to 60°C operating range) and current flow (30A max discharge). The battery pack includes redundant short-circuit protection, over-discharge lockout at 8.5V, and moisture-resistant casing (IP54 rating). Thermal runaway prevention uses ceramic separators between EVE 18650 cells.
The multi-layered safety architecture incorporates three independent protection circuits. A primary PCB manages cell balancing during charging, while secondary circuitry monitors discharge rates. The third failsafe system triggers immediate shutdown if internal pressure exceeds 2.5kPa. This triple-protection design ensures safe operation even when drilling through hardened materials like stainless steel or concrete.
“The BAT411 represents the gold standard in tool batteries. Its use of automotive-grade EVE cells typically seen in EVs ensures unmatched durability. We’re seeing 23% fewer warranty claims compared to previous generations. The real breakthrough is the adaptive load sensing that prevents voltage drops during high-torque applications.”

Frequently Asked Questions
- Can I use third-party chargers with BAT411?
- Only Bosch AL 10.8-12V chargers (model GAL12V-40) are recommended. Third-party chargers may void warranty and risk overheating due to incompatible charging algorithms.
- Does cold weather affect performance?
- Below 0°C, capacity temporarily reduces by 20-30%. Store batteries in insulated cases and warm to 15°C before use in freezing conditions. Never charge below 0°C.
- How to dispose of worn-out batteries?
- Use Bosch’s free recycling program (available in 58 countries) or certified e-waste facilities. Never discard in household trash due to fire risk from residual charge.
