Just looking more closely on the Li-On battery on the Bosch strimmer - thought it said 4 Ah. What it actually said it BIG was 4 AII and below that small was 1.2 Ah.
The size kind of gave it away anyway, but I thought 4Ah eh mm wonder if it will fit my newish DeWalt DCD776 drill :-) (I won't of course, but worth a look).
OT: And about that drill, it's very well made and am very please with it, except for:
The led - great idea but the beam is obscured by the chuck so cannot see the drill bit in its light. I hear even newer models have the light near the handle base.
The chuck is not as "positive" as the one on my old DeWalt NiCad in that it releases the bit sometimes under vibration.
A real gem on the old drill was that bit-holder moulded into the case
- is absent in the new drill. WHYYYYYYYYYYYYYY!!!! It was so useful.
