I am interested in purchasing an EGO 15" cordless string trimmer.  It comes with a 56V battery.  I understand from the reviews it would be handy to have a second battery.  Can you advise which one to purchase?  There seems to be a 2.0 and 4.0 for sale through Home Depot online.  Would either suit?  What type comes with the tool?  How long will it take to charge each?

The trimmer doesn't eat through battery's.  The trimmer with battery comes with the 2ah battery.  If you have other EGO tools, grab a 5ah and be done with it  :)

Depending on how hard you're working the 15"'trimmer, with a second 2Ah battery you could almost have continuous use since that battery charges in only 40 minutes on the standard charger (included with the trimmer kit). Most people report getting 30 minutes or more of steady trimming with the 2Ah battery.

Unless you need more than 60 minutes of continuous trimming time, two 2Ah batteries would work very well.

The larger batteries will last much longer but will also take longer to charge. They also weigh more, which may or may not affect your comfort level holding the tool for long periods.

I have the mower, string trimmer, blower, and hedge trimmer and have (1) 4Ah which I use in the mower, and (2) 2Ah batteries which I use in the other tools. This arrangement works very well for me and suits my needs perfectly.

I think the 2Ah is plenty for all tools except the mower and blower. If you have plans to add either of these then you may want to consider a larger battery. Keep in mind that a rapid charger is $100 unless you buy a mower kit, and it will take a long time to charge a 4Ah battery on a standard charger.

Personally, I would rather get the new 2.5Ah battery for the extra 25% more run time without any added weight.
