Reverse of the insertion process; hold charger steady with one hand, pull battery off with the other. :-)

Like asking God for help and get a bolt of lightening!

Yep, it just slides off. It can be a tight fit because the electrical contacts are snug, but there's no release mechanism or anything.

I was just apprehensive as to force applied -- all well now and thanks for the needed reassurance!

I have my charger hanging on a wall.  Still have to hold the charger with one hand and pull the battery up and off with the other.  Otherwise, the charger wants to come off the wall, too!
I suppose I could hold the charger down with a couple of screws in the wall wedged to the top of the charger.  But not very pretty and shows poor workmanship on my part.  I don't like that one bit.

Ego, have any suggestions?  Am I missing something obvious in the mounting layout for the charger?

Hi Irving! Are you sure that the charger is mounted properly? Here is a diagram from the manual for reference:

I'm not sure I understand the issue with having to hold the charger when removing the battery? What is the other hand being used for? Is there some kind of release button you have to press on the battery?

Just the natural friction of where the battery engages the charger makes it so you kind of have to hold the charger with one hand while lifting the battery with the other. My chargers are free standing on a shelf, but I'm thinking of wall mounting them and that may remove the having to kind of hold the charger while removing the battery.

Looking at the diagram, if you hang it on the wall you could install a stop device, maybe just a screw or a small block of wood, etc., above it to prevent it from lifting up as you pulled up on the battery - ?

Sure. That just doesn't help folks who prefer to keep their chargers on a shelf or workbench. Not sure how many would be willing to bolt their charger to a horizontal surface as it could make it difficult to move it out of the way if that surface were needed for some other reason. Unless it were dedicated space for the charger.

I would probably get a roll of the eyes from my wife trying to make the case that using two hands to disconnect a battery from a charger is an inconvenience when I am about  to spend 30 min or an hour pushing a 40+lb lawn mower around the yard in the sun. :)

For some who have posted here,  they need both hands just to handle the larger Ego batteries, 5 and 7.5 ah. Operating the mower is the easy part for them, it's a grip problem for them with getting the battery in and out of not only the mower but the charger too.

I see. Maybe Ego can come up with a viable solution for them.

Yup, even something as simple as a handle or strap across the top of the battery.

We're passing these ideas on to the team. :-)

Amber, I am using the keyhole mounting holes on the back of the charger.  I didn't place the mounting screws so close to the surface as to possibly crack the case of the charger.  But, in doing so, there is slop enough to lift the charger from the wall if not held in place my some other means.  E.g. an extra hand.  I like the idea of a small block at the top just to hold the beast in place.

Even better, how about replacing the keyhole method with a couple of through holes? Through holes from the front of the charger would allow you to pass fasteners through the charger from the front and just screw it down to a surface. Much easier I think.

Of course, this will only help us with next generation chargers, not the current ones.

Can any of the different battery types be charged on any version charger (if there are different versions of the charger). For example I think my battery is 2 ah, can I buy a 5 ah and charge it on the same charger?

I suppose as battery capacity inevitably increases with time, we could see an even more powerful charger offered. The current chargers should still work though, they’d just take longer to charge higher capacity batteries.

And one would assume the more powerful charges would not be backward compatible - ? Unless they were designed to recognize older batteries and limit current accordingly...?

It’s all speculation at this point. Ego has the fastest charging in the industry right now, by a long shot, so I can’t see a pressing need for significant updates any time soon.

That's good to know. Seems like an important metric, I wonder how it's managed.

If you consider the European market 1300W battery back pack; that one is about 23 Ah (1300 / 56), or about three equivalent 7.5 Ah battery packs.  And the manual says it is charged with the CH5500 (rapid) charger, but it also does not contain a warning that says not to use the CH2100 (standard) charger.  Presumably you could use the standard, it would just take a lot longer.

As Blue said above, Lithium is charged by CC/CV, so whether it is a 2.0 Ah or a 23 Ah battery pack, the charge method is the same.  To the comment about a newer charger needing to detect and limit the current for smaller batteries, that would be a prudent design feature to protect the long term performance of the battery pack.

However, the slower you charge a battery (vs. rapid), the generally better it is for the long term battery life.  I own both the standard and rapid charger, and I used to use the rapid so that I could intentionally only charge the pack to 50%; but now that I have the ability to measure the (re)-charged state of the pack [1], I'm going to exclusively use the standard charger, as slower recharges can only help to preserve long term battery life.  The average customer can do the same without a modified charger by measuring battery voltage (discussed in linked thread).
