Quick Facts – FLEX Li-Ion Battery
- Brand: FLEX
- Model: FLE000265 (AP18.0/5.0)
- Battery type: Li-Ion
- Voltage: 18V
- Capacity: 5.0Ah (90Wh)
- Protection rating: IPX6, dust and water resistant
- Charging time: approximately 45 minutes
- Thermal management: KEEP COOL technology
The FLEX 18V Li-Ion Battery delivers 5.0Ah capacity (90Wh) and reaches a full charge in around 45 minutes, built for continuous use in the workshop and out in the field. The battery is rated IPX6 for dust and water resistance, making it suitable for demanding working environments. KEEP COOL technology reduces heat build-up under load and contributes to a longer cell lifespan.
The battery works with all FLEX 18V tools and serves as a central power source for professionals in construction, service and vehicle reconditioning. An electronic control system coordinates charging and discharging for consistent output throughout the entire use cycle. More FLEX tools for professional use can be found in our range of FLEX tools.
What sets the FLEX 18V Li-Ion Battery apart?
The battery combines high capacity with several protective functions in the same package. KEEP CONTROL technology continuously monitors the cells, and protection against overcharging, overcurrent and overheating ensures safe charging cycles. High-performance Li-Ion cells provide long runtime without adding notably to weight or size.
A charge indicator shows the current level directly on the battery, making it easier to plan work sessions without interruption. The combination of KEEP COOL and KEEP CONTROL makes the battery a stable choice for users who need consistent power output over time.
Where the FLEX Battery performs best
The battery is designed for work in environments where dust, moisture and heavy workloads are an everyday reality.
- Construction sites with dust and moisture
- Reconditioning workshops and detailing studios
- Outdoor service and maintenance work
- Workshops requiring long runtime without charging interruptions

Frequently Asked Questions (FAQ)
Does the FLEX 18V Li-Ion Battery fit tools from other brands?
No, the FLEX 18V Li-Ion Battery is designed for FLEX's own 18V tools and is not compatible with tool systems from other manufacturers. The battery does, however, work with all tools in the FLEX 18V range, making it a flexible power source for those who already use FLEX tools.
How should the FLEX 18V Li-Ion Battery be stored when not in use?
The FLEX 18V Li-Ion Battery should be stored in a dry, cool place with the cell partially charged to preserve capacity over time. KEEP CONTROL technology helps protect the cells even during extended periods of inactivity, but we recommend avoiding extreme heat and full discharge during storage.
What distinguishes the FLEX 18V Li-Ion Battery from other 18V batteries on the market?
The FLEX 18V Li-Ion Battery stands out through the combination of KEEP COOL thermal management and KEEP CONTROL battery monitoring, which together reduce heat build-up and contribute to a longer lifespan compared with batteries lacking equivalent protection. The IPX6 rating also provides dust and water resistance that is not standard across all competing 18V batteries.
