& they do sell power packs with 18650s in for their power tool range, did you drop AA[etc] or 18650s? I assume the later.
AAs.
One might need to delve into the exact detail of what is defined as a 'portable' battery.
I found this;
Portable battery definitions and types
www.g-pbatt.co.uk
And a portable battery appears to be defined as;
Lead acid batteries
- Sit and ride toys
Alkaline/Zinc carbon batteries
- Clocks
- Torches
- Toys
Primary (single-use) Lithium batteries
- As an alternative to Alkaline
Secondary (rechargeable) Lithium Ion batteries
- Mobile phones
- Laptops
- Power tools
Nickel cadmium batteries
- As a rechargeable alternative to power tools
Nickel metal hydride batteries
- As a rechargeable alternative to power tools
Silver oxidebatteries
- Button cells used in watches or hearing aids
Mercury oxide batteries
- Button cells used in watches or hearing aids
Zinc air batteries/Air depolarised batteries
- Hearing aids
- Clocks
So if the 18650s in a power tool battery are 'Portable' one might assume that they do indeed accept them for recycling.
