The Bosch 12V 12.8AH Ni-Cd Battery is designed for high-performance power tools like the GSB, GSR, and VE-2 series. With 12.8Ah capacity and Ni-Cd technology, it offers long runtime, durability in extreme temperatures, and compatibility with multiple Bosch models. Its EVE Battery cells ensure stable power delivery, making it ideal for professionals needing reliability.
How Does the Bosch 12V 12.8AH Ni-Cd Battery Compare to Lithium-Ion?
Ni-Cd batteries like this Bosch model excel in cold environments and tolerate deep discharges, unlike Li-ion. While heavier, they offer a longer lifecycle (1,000+ charges) and cost less. However, Li-ion batteries are lighter and have higher energy density. For heavy-duty tools in harsh conditions, Ni-Cd remains a robust choice.
In sub-zero temperatures, Ni-Cd batteries maintain up to 85% of their capacity, whereas Li-ion batteries can lose 30-40% efficiency. This makes the Bosch 12.8AH ideal for construction sites in winter or refrigeration repair work. Additionally, Ni-Cd cells are less prone to thermal runaway, reducing fire risks in high-stress applications. While Li-ion dominates consumer markets due to weight savings, professionals prioritize the Bosch Ni-Cd’s resilience in unpredictable environments.

What Tools Are Compatible with the Bosch 12V 12.8AH Battery?
This battery works with Bosch’s GSB 12V drills, GSR 12V screwdrivers, VE-2 vacuums, and models BAT043, BAT045, BAT046, BAT049, BAT120, and BAT139. It’s backward-compatible with older 12V Bosch tools, providing seamless integration for users upgrading their batteries without replacing tools.
The battery’s universal 12V rail system ensures quick attachment to over 20 Bosch tools. For example, the GSR 12V-35 screwdriver paired with this battery delivers 35 Nm torque for automotive assembly lines. Similarly, the VE-2 vacuum runs for 45 minutes on a single charge, making it suitable for drywall cleanup or workshop maintenance. Contractors using legacy Bosch equipment appreciate the backward compatibility, which eliminates the need for costly adapters.
| Tool Model | Application | Runtime (Minutes) |
|---|---|---|
| GSB 12V-30 | Concrete drilling | 70-80 |
| GSR 12V-35 | Cabinet installation | 90-100 |
| VE-2 | Workshop cleanup | 40-45 |
Why Choose a 12.8Ah Capacity for Power Tools?
A 12.8Ah capacity extends runtime by 30% compared to standard 2.0Ah batteries, reducing downtime. It supports high-torque applications like drilling through metal or masonry. The higher amp-hour rating ensures consistent power output, preventing voltage drops during demanding tasks.
How to Maintain a Ni-Cd Battery for Longevity?
Fully discharge the battery monthly to avoid “memory effect.” Store it in a cool, dry place at 40-60% charge. Clean terminals with isopropyl alcohol to prevent corrosion. Use only Bosch-approved chargers to prevent overcharging. Avoid exposing it to temperatures above 113°F (45°C).
What Safety Certifications Does the EVE Battery Cell Have?
EVE Battery cells meet UL, CE, and RoHS certifications, ensuring compliance with international safety and environmental standards. These certifications guarantee protection against overheating, short circuits, and hazardous materials, making the battery safe for commercial and DIY use.
Can This Battery Be Recycled?
Yes, Ni-Cd batteries are recyclable. Bosch partners with Call2Recycle and other programs to handle proper disposal. Cadmium is toxic, so never discard in household trash. Recycling recovers nickel and steel, reducing environmental impact.
What Are Common Signs of Battery Failure?
Symptoms include rapid discharge, failure to hold a charge, or physical swelling. If the battery overheats during charging or shows corrosion on terminals, replace it immediately. Most Bosch Ni-Cd batteries last 3-5 years with proper care.
