Battery Problem: Charger vs. Rapid Charger and Lack of Knowledge on Help Desk

Last week I go out to my mower (20 inch walk behind) and sure enough, I forgot to pull the battery out to charge from the last use. Long story short, I cannot get the battery to charge. Nothing. Sometimes a green flash and then faster green flashing on the Rapid Charger (too fast, I recognize a more measured pace when charging correctly), or simply red flashing - defective battery.

I call customer service. We walk through troubleshooting and they tell me "Defective battery, out of warranty, sorry". Not too happy about this, as the mower is just about 4 years old and the same with the battery (mower, 5 yr warranty, battery, 3 yr).

I decide to buy a chainsaw with 5.0 Ah battery and Regular Charger. I figure what the heck, it's 50 bucks more than the battery and I get the chainsaw to boot. Chainsaw comes with Regular Charger - not Rapid Charger.

Long story short, my defective battery charges fine on the Regular Charger and works fine in the mower again.

With two batteries now, I question whether I should ever use the Rapid Charger.

Customer Service/Support had no input on Regular vs. Rapid Charger, but I did find a video online where a person had disassembled a battery and found that one cell was undercharged, which caused the battery to report as defective. I did not disassemble anything, I just threw what was supposed to be a defective battery on the Regular Charger which seems to have fixed it.

It is no consolation but the answer from CS would have been the same.  It is a 3 year warranty on batteries and chargers.

Good news is you have 2 good batteries and a nice chain saw.

Have you tried unplugging the charger for a minute or so?  It may just need to repair with your battery.

Yes, I tried this a couple times to no avail. The only thing that worked was using the Regular Charger.

Well now, good thing I have a standard charger to go with 2 rapid chargers. Will keep this trick in mind.

OK so here's an update since I just mowed my lawn completely. The "bad" battery worked fine for half the yard and then started losing power. I threw it on the Regular Charger and it started charging as expected, and I continued mowing the lawn with the new battery. Came back into the garage about 30 minutes later, and now the Regular Charger was blinking red. I threw the battery on the Rapid Charger, and it then continued to charge up to full and the charger turned off. I am inclined to think that I'm not going to get much more life out of this battery.

I agree. Even if one battery only lasts me half the yard, it's still nice to have two batteries. I don't have that large a yard and sometimes the (old) 4.0 Ah would not last the entire time, even when new. I do wonder if I could get away with just buying the snow blower with no batteries but I am concerned that the old/"bad" battery would drain too quickly to be effective under load from the snow blower.

And I did not realize this: The Rapid Charger has a memory or pairing with each battery?

There is no memory or pairing between EGO batteries and chargers. Any EGO battery can be charged in any EGO charger. I'm not sure where the pairing/marriage comments came from but it's not the case. 
Unplugging the charger, waiting a bit and then plugging the charger back in only resets the charger (potentially). 
It seems as though the standard charger sort of kick started your older battery. I admit I haven't read through all of your responses in this thread but have you tried the older battery in the quick charger again since the battery seems to be "fixed"? Have you tried the new battery in the quick charger?

It comes from the Battery/Charger manual.   The initial steps direct you how to initiate the charger and battery when you first charge a battery.  All I was saying is perhaps for some reason one or the other reset back to the factory preset and needed to be rebooted.  I did not mean to imply that a battery is dedicated to a single charger.  Obviously that is not the case.

per manual

DEFECTIVE BATTERY PACK OR CHARGER
If the charger detects a problem, the red LED will begin flashing and the green LED will go off.
1. If registering as defective, remove and reinsert the battery pack in the charger. If the LEDs still read “defective” a second time, try charging a different battery pack.
2. If a different battery pack charges normally, dispose of the defective battery pack (refer to the instructions in the battery pack manual).
3. If a different battery pack also indicates “defective”, unplug the charger and wait until the red LED goes out, then reconnect the plug to the power supply. If the red LED on charger still displays defective, the charge may be defective

Yeah, but no real initialization or pairing, just communication between battery (any battery) and charger.
