Battery AH Explained

The best way to describe battery amp hour is that this is effectively the size of your fuel tank, the more amp hours your battery has then the longer the battery will last between charges. More amp hours does not increase the power of a given tool.

Battery Voltage Explained

A tool with a higher voltage than another is a bit like choosing an engine in a car, the higher voltage will generally mean higher power & performance. As with cars though a bigger engine does not always translate to better performance so it is important to compare the specifications of tools at different voltages between different manufacturers.

Q : looking at buying a bosch albi 3620 leaf blower will this charger work

TooledUp answered on 30/09/2020

A : I don't recognize that part number but it sounds like it is probably a 36v machine? If so, this charger won't charge the batteries as it is only suitable for 18v batteries, but also note this is a Bosch Professional battery charger so will only work on batteries from the Bosch Professional (blue) range of power tools. I am guessing you are looking at a Home & Garden (Green) 36v leaf blower which would need a charger such as the one we stock on product ID 21006777 - however, it may make more economic sense to buy the machine complete with a battery and charger to start off with. For example the Bosch ALB 36 Li we stock on product ID 21000144 can be purchased complete with a charger and battery at the moment for not too much more than the charger costs by itself.
