Question about Bosch Home & Garden Charger AL 36V-20

I can't answer that.
I use it to charge the Li-ION batteries (36V, 4.0 Ah, 144.0 Wh) from the Bosch lawnmower.
They fit on this charger. Caution: The device and battery must not
not get too warm when charging (do not charge in direct sunlight)...
