I don't have a leaf blower, but from my experience of other battery powered garden tools - don't bother.  Unless you got one with  a very high capacity Li-Ion battery, It probably would run out of puff very quickly.

Yes Ruby, I've been trying to rake the leaves off my garden and it's not easy.   There is a Bosch blower with an 18V, 2 amp Li battery on Amazon.  It quotes UP TO 14mins, so maybe more like 10 mins. 

I tried a Bosch hedge trimmer for my garden, but even with two batteries, it wasn't up to the job.  I've got a mains one which is much better , though I need a 50 mtr lead to reach the back hedge and that has its own problems!

Write your comments here...I too have a Bosch hedge trimmer with two batteries. I have been very please dwith it. With my arthritis I find it knocks me about less than a mains one. After about 4 years usage though the batteries were getting tired by the
start of this season. I got a pair of replacement batteries for £35 from Amazon and back to normal

EasyT, the Bosch trimmer was pretty decent, but simply wasn't up to the job of trimming about 40 mtrs of mixed hedge.

For leaves, there's nothing wrong with a broom or a lawn rake, but it's hard work when you have  four mature trees dumping their leaves on the garden when there's a north wind.

If the leaves are dry, I sometimes run the lawn mower (self propelled) over them and they get mulched into the collecting box.
