This conversation has been merged. Please reference the main conversation: Battery compatibility?

I am considering the 21" self-propelled mower (model LM2102SP) and the blower (model LB4800).  There are several comments on the website that any battery can be used with any tool.  However, the mower shows it uses a 7.5 Ah battery (BA4200), but the blower manual (page 9) indicates it can only use battery pack BA2240 or BA1120.  Would the 7.5 Ah batter fit and work safely with the blower?

Thus far, all the Ego tools are compatible with all the Ego batteries.

Some batteries are better suited to specific tools, but they all work together. The 7.5 Ah battery is large and heavy and can make smaller tools (like the hedge trimmer) awkward to use. On the other hand, the 2 Ah battery will only run the mower, snowblower or other power-hungry tools for a short amount of time. 

I personally would go with one of the newer blower models, but that's just me.

The self-propelled mower does come with the 7.5 Ah battery to help extend the runtime, but it's true that all of Ego's batteries are cross-compatible with all the tools.

As Dominic said, the 7.5 Ah battery will feel a bit heavy on the blower, but you can probably minimize that by using a shoulder strap to take some of the weight.

Robert, I had a similar question about this last year.  At the time, I was not yet part of this "forum" so I contacted Customer Service (CS) and got the answer I was looking for.

  • All EGO batteries are "cross functional" across all EGO power tools
  • Obviously, the "higher Ah" batteries will provide longer "run times" with smaller handheld tools
  • Lower Ah batteries can be used with non handheld tools (e.g. lawn mowers, 16" chain saw, backpack blower, 575 CFM blower, and snow blower), but not recommended

Don't want to get too "technical" into the battery draws from each power tool on this thread, as it has been mentioned "to death" already.  Good luck with your new purchases, and keep us posted on your final decision.

I'll mention one last detail. The reason the 7.5Ah battery isn't mentioned in the LB4800 manual is, that blower pre-dates the 7.5Ah battery. If they were to re-issue the manual today the 7.5 would be included. :-)

Just a a side note on the batteries... There are actually 5 different sizes of EGO batteries available currently.


Each one has a place in my tool lineup!

I have that blower and I also have that size battery.  I have used both together and they work perfectly.  I have used that blower with the 2.5Ah, 5.0Ah and the 7.5Ah batteries, as I have all three of them.

My observation.  the smaller battery is much lighter, but I found as I used the blower the lack of weight in the blower made it tend to blow back on itself when using a higher speed.  It to me ended up feeling more tiring to use as I was fighting with the blower to keep in on target.

The mid and large batteries felt more comfortable to use.  If I had a choice, I'd use the 5.0Ah battery as it was a bit lighter and give me more than enough time to blow all the leaves in both my front and back yard.  The 7.5Ah battery was a bit heavier so you did feel it a bit more after blowing for an hour or so.

Now, having done a season with the blower, I'd probably end up doing the yard differently this year.  Rather than trying to blow everything into a single big pile, I'd break the gathering into smaller sections as I found out afterwards that I ended up blowing the pile back together several times as I gathered them up to brown bag them.  In my neighbourhood the town doesn't suck up leaves.  With this in mind, I doubt that the larger battery would really feel any different as I'd be blowing for 10-15 min and then putting it down to bag for an equal amount of time, before picking back up and blowing again.

Hope this answers your question better.  YES the blower can use any size EGO battery, but I actually prefer the larger ones.

Great summary Matt!
