Ego Battery Degradation
#1

How's everyone's EGO batteries holding up?

 

I got 3 batteries almost 2 years ago, used only in 1 tool, the line trimmer.  I estimate about 50 hours of run time on each battery or about 100-150 charge cycles.

 

Original batteries have degraded and seeing various issues-

- Run time is only about 1/3 to 1/2 of what they were new.

- Seem to discharge by themselves quite often, if not used for a couple of days charge will be very low or completely flat again

- 1 battery completely died and failed to charge after about 12 months, replaced under warranty, then died again about 12 months later, replaced again.

 

So I have 1 new battery which has been replaced twice and two older ones which are now almost useless.  Considering only about 100-150 charge cycles it's not great.  Something to consider especially if you are running the mower a lot or multiple EGO tools I can see the need for the batteries to be replaced often.   Think their  battery warranty is 2 years, no idea if this covers normal degradation during this time or what the warranty is for commercial, but must also consider the painful EGO warranty process.

Do you run them flat? Lithium’s are best recharged as soon as you feel them start to drop off. Going dead flat is bad for them
That said I don’t think I’ll be investing further into ego products.

Yeah I run them flat, supposedly EGO batteries though don't go 100% flat though to avoid this issue, when they are "dead" they still retain a bit of charge.  They also automatically discharge after 30 days of non use, problem is my old ones seem to do this after just a day or 2 of non use.

My ego gear is fairly new and still working fine, but speaking from using gear from Bosch hilti de Walt etc in the past, it’s best to keep them above 70%, easy if you can charge while you work but if not it’s a bit harder. When we used them in drills, as soon as the battery felt like it wasn’t full we swapped it out, they top up pretty quick and good to go again. If you flatten them they take ages to charge as well.
Batteries only save weight and noise, definitely not money.

Sounds to me your battery is cactus.

Ego claim 1000 recharges and warranty (non commercial) 3 years, think it,s 1 year for anything commercial but havnt seen their definition of commercial.

i doubt if you could call it commercial use if your doing 1 small lawn a fortnight and your own place.

Do you have a link to this 1000 recharge cycle claim?

The life of all batteries is based on charging cycles. So typically our batteries will get around a 1000 cycles before losing capacity significantly.

 

 

 

Thats from the Q. page on the plastic deck sp mower, you,ll need to look at reviews and scroll down

EGO Speaking #### I reckon, 1000 cycles my arse.  Like I said I've done maybe 150 cycles at most and they are less than 50% of what they were new.

Almost impossible to make a case unfortunately I reckon - unless the battery logs charge cycles - and then with Lithium the recommendation is to topup charge regularly rather than full discharge before charging so how many real "cycles" has it done - lawyers playground

Ego Battery Degradation
#11

I'm not using my Ego gear commercially (so, keeping that in mind) I've had a ~ 6 month old 2.5A/h battery do strange things. I tried to charge it (cold, it had been sitting for a while) and it kept cutting out on the charger as being full. I knew it wasn't full but then tried to use it with the multi tool chainsaw and it quickly cut out. I then charged it straight away and it did accept charge.

 

It's been working okay since then and I've been using the chainsaw a bit. My older battery hasn't ever behaved the same way.

 

I do find the batteries can cut out on the multi tool chainsaw prematurely. I'm guessing it's the over temp or over current protection? "Babying it" can get a lot more run time out of a battery that has previously cut out. By that I mean waiting a minute or so after the initial cutout, then not aggressively cutting into wood as the chainsaw starts up.

This is probably worth a read, it also discusses battery charge temperatures

https://batteryunive...store_batteries

The above site has answers to most battery related questions

 

If you put some (uncooked) rice or some of those silica gel packets in the storage bag that will help control moisture/condensation, especially if you are putting warm batteries into the fridge.

I think occasionally used or for longer term storage, Li-ion batteries are best stored at lower charge levels, not full and a cooler environment is preferred.

 

Free advice/conjecture, so value it at that.

I've had a good trot with my 4 batteries - one was DOA and replaced - no idea on runtime or number of cycles but I'm not sus about any of them -

 

one thing I don't do is leave them on the tool in the back of the ute in summer - I've got a black tonneau cover and the temps underneath get horrendous - except for the blower which is in and out every job I keep the batteries in the cab until needed - if I'm stopping for lunch I'll put the blower in the cab also - when I get home I let them go down to room temp before I put them on charge.
