Where do I find the battery serial number?

I just purchased the ST1502S unit which comes with a battery, charger and the 15 inch hinged trimmer. There is also a promotion going on at Home Depot that also included an extra battery. However, while I found the serial number for the trimmer and the charger, I cannot find a serial number on either the included battery or the extra battery. I looked at the picture the website included showing the serial number is supposed to be on the side sticker where the battery slides in. I have the warning stickers on both inside sides, but NO serial number. What is your suggestion?

Did you open the promo battery? When I registered mine I thought I could not open the package but you have to to get the serial number.

Why are you not supposed to open the package of a battery that you're registering.? If you're registering it you're keeping it, right?

I understand the point is that you need to take the battery out of the package to see the serial number.

Cupcake,

Two options.

Option 1... Don't register the battery and return it to get money back because you might not need the battery anyway.

Option 2... Make sure you've opened the package to see the serial number. You may want to do this anyway because you may want to charge the battery and use it now and then for its own health.

After a battery sits for a month it goes through a maintenance procedure where it discharges to 30% for long-term storage.

I'm not sure about others, but I think it would be unhealthy to let a lithium ion battery sit for long periods of time not being used. I mean really long periods of time. That's why I suggest that you might want to open the package, to charge it and use it now and then. Or at least charge it now and then and let it discharge itself after a month. Then wait a longer period of time before you charge it again... To restart the cycle for its own health.

Personally I would probably just swap the extra battery in and out with one of your other batteries to make sure that they're all used now and then.

Ego recommends charging their batteries once every six months during longer periods of non-use. I'm sure they can survive MUCH longer than that without being charged, but it's probably a good practice to do it anyway just so it doesn't get forgotten.

In the grand scheme of things, cycling the battery every six months is sure to have a negligible impact on its lifespan.

Thanks for the comments but the issue is the location of the serial number. I did unpack both batteries. The promo battery was not packaged as a special. It was simply one of the batteries on the shelf where you could purchase it as an accessory. When the trimmer ran up, and the extra battery ran up, the computer automatically credited the amount of the separate battery and I wasn't charged for it. My issue is that I can't find a serial number on either battery anywhere. According to their webpage is is part of or just below the sticker on the inside edge of the underside of the battery. I have the sticker with all sorts of warnings but there is no serial number under it, over it or next to it. I looked on all surfaces and I don't see any serial number. Since the product code for the trimmer includes not only the trimmer itself, but also the battery charger and the battery, I am unable to register any of them without putting in a serial number for all of them. BTW, I agree that you should rotate and charge all the batteries periodically. But I have such a large piece of property, that I am anticipating using both batteries each time so I expect they will be routinely charged. But I would really appreciate if if anyone can tell me where the serial number for the battery is on these 2 amphr batteries.

Here is my serial number... The number is covered up because I haven't registered it yet... Let me know if it helps.

Yes, so it's not where it slides in but on the top and visible even while attached to the tool.

I was going to say the same thing but didn't have a pic of my battery to share.

The earlier batteries all had the serial number on the inside where the contacts are, but the newer batteries have slightly revised cosmetics (see the new 2.0Ah label beside the Ego logo, top of the pic) and the serial numbers moved from inside to outside.

Thanks Kid Rock and Blue Angel... I did find it where you said I would. I was apparently so focused on where it was supposed to be that I missed it where it was... all set now.. Thanks!!!  One that did bother me was that when I found the serial numbers, I discovered the extra battery had a manufacturer's date of 2 years ago!! But since it's still covered by their 3 year warranty, I am not going to worry about it

Any time! You know where we are. :-)

You are correct, the warranty clock starts ticking on the date of purchase. Also, Ego's battery packs have a long term storage mode built in that maintains their charge level at 30% during long periods of non-use. This ensures that the cells in the battery are not stressed during storage and no undue capacity loss takes place. It automatically kicks in after 30 days.

This is the reason most companies package Lithium batteries with the cells at a partial charge level; so they are not under stress during time before purchase.

Geoff, thanks for letting us know that the images on our registration pages for the battery serial number location are outdated.  Those are being updated now and should be live tomorrow.  We hope this helps more people in the future!  We're really sorry for all of the confusion we caused.
