What to do with all my batteries?

With the sales, rebates, and discounts I replaced several of my tools with EGO. I now have 5 batteries. With my power tools I have several batteries but they are all the same size although with improving technology some have higher Ahr ratings than the others.

With EGO I have 7.5 (lawn mower), 5.0 (chain saw), 2.5 (string trimmer), 2.5 (blower), and 2.0 (hedge trimmer) Ahr batteries. In use I think I could get away with just the 7.5 & 2.5. Guess I could sell the spare batteries but don't want to suffer seller's remorse. I also don't just want to have these valuable batteries sit.

What have others done?


Thanks

Kinda depends on what kind of work you do. I'd be tempted to keep one of each 2.5, 5 and 7.5, that way you've got a battery for every situation.

The 5Ah is a sweet spot for higher powered handheld tools like the power head and chainsaw. The 7.5 might be a bit heavy for handheld work, but it does belong in the mower.

However, a tool like the hedge trimmer REALLY benefits from the lighter batteries, or should I say your arms do! If you do tons of work with the hedge trimmer and need more than one small battery to get through, then keeping both 2.5's makes sense.

I don't know if that helps or not, just the way I see it. :-)

I would keep all the batteries.  You could sell them, but you really ought to disclose that the warranty will NOT transfer; therefore, any second buyer is taking a risk that the battery could fail the next day, and Ego will not warranty.  Therefore, you'd likely have to deeply discount the batteries.
If you were to keep them, you are covered under warranty for three years.  And then after that, you may get lucky and the batteries will still work at a reduced capacity.  Having spare batteries might allow a tinkerer to cobble together a more capable set from a couple lesser ones.  That's my plan for my more "elder" Ego batteries.

How much "reduced capacity" do you foresee after three years of storage or light use?

I'd be willing to bet batteries used on a weekly basis would still have 90% or better life remaining after three years, unless they were mistreated. Batteries that were stored or cycled a few times a year would fare even better.

I agree about the lifetime of the batteries,all this talk about batteries failing or giving up seems a bit over the top. I have a lot of cordless tools and lithium batteries and after ten years or more I have yet to lose a single cell. I only cut my yard five times a year so battery life is expected to last twenty years. I also keep the batteries topped up and inside away from constant temperature changes.

"Only cut my yard 5 times a year"  would like some details on that

My location is dry and I don't water of fertilize my grass, all it needed this summer was three to five cuttings. It does however grow quite high in a a few places and that is where I found out this mower has a few surprises. I thought I would run the battery down by going at some deep damp grass I had no idea the motor was set to run at a certain speed. When I hit the deep grass the electronics boosted the RPM really high, I had no idea it even had the ability to do that. Also it senses the moment you leave a heavy area and spins down to normal power.

I rotate mine. Any battery has a limited set of charge cycles. So I think rotating will make them last longer.

I have a 7.5 and two 2.5. I use the 7.5 in the mower, then the 2.5's are rotated in the blower and hedge trimmer. I suppose only having three makes it easier to manage a rotation, but that's what I would do, keep them all and rotate.

Keep them, it ever you have a really heavy job you will need them, went through a 7.5, a 5 and a 4 AH batterys in just over an hours worth of medium to heavy strimming, excellent kit but the average ' battery life' oft quoted on here must apply to light work..
