Default I2 SE - battery charging but not?

Hi all - recently purchased a used i2 SE, and Iím having an issue weíre diagnosing together (both myself & the seller - theyíve been super responsive and helpful!)

Long story short - when I plug the i2 SE in, Iím getting two green charging lights, but it doesnít appear the batteries are ďtakingĒ the charge. Iíve only had it a few days but Iím down to 3 bars left on the Infokey. Iíve charged it pretty much 24x7 the last few days, and I just continue to get the solid green lights - it never goes to blinking and upon powering up, Iím at the same level on the Infokey that I was at before charging. It does deplete as I take it out and about.

Any suggestions whatís going on? The seller will be calling Segway Inc shortly on my behalf but I thought Iíd poke at the collective wisdom.

The only thing we could come up with is that itís cold outside, but itís being charged in a heated garage. Itís about 64 degrees in the garage, so I doubt thatís it.

Any ideas?

Thanks!

Default Worth a shot

I don't know the answer.
But given the holidays, this is what I would try whilst waiting for those Segway experts to respond.

It 'smells' like most of the gear is working, and maybe you have had a glitch ( did you have any thunderstorms or power blackouts ? ).
So I would try to re-start it.

To do a cold reset, remove both batteries.
Leave them off for a decent time, say 15 minutes.
( observe the battery date codes, or just post the first 6 digits here ).

Re-fit the batteries and see what happens.
Good luck.

How about running it until the batteries deplete themselves, then recharge. I've read somewhere that this re-celebrates the level of charge.

Yes, good catch. Just leave it running, parked pressing against a wall, until it stops. Then charge.

(See "recalibrate" in the reference manual.)

Wasnt there a problem with the charging of the first runs of the SE?

I thought I read it here?

Recalibrating (or 're-celebrating') the gauge is probably a good idea, but I would first want to know for sure that it *will* recharge before running them all the way down and *then* discovering that it won't

Bingo. Thatís entirely my concern. Right now Iím planning to swap front/rear batteries but fighting a stripped screw in the front battery. Hoping to get it out fairly cleanly - going to try a slightly oversized hex head, then a torx driver and worst case, put a little epoxy on a sacrificial hex key and let it cure overnight. When it rains, sometimes it pours. :-/

Thank you Michael! I've managed to get the stripped screw out (anyone got a source for replacement battery screws?) quite easily by using an SAE hex driver one size larger. Trying to be delicate but finally got it to break free and was able to coax it out.

Left the batteries out for a few minutes, swapped positions and reinstalled. Let's see what happens. No thunderstorms, blackouts or brownouts either. All good there.

Anywho - serial #'s are:

C051414xxxxx
C091813xxxxx

Both are Revision AH. Segway has 3750 miles on it.

So let's see what comes from a few hours on the charger... I'm down to 2 bars right now, so hopefully this gets sorted quickly. Again, the seller offered me a 6-month guarantee against any issues - and reiterated that when I mentioned the charging issue - so I'm sure it'll all work out in the end with a happy Segway... just want to get it sorted.

Default Battery Life

OK

My experience is that Segway batteries should last about 10 years, if well looked after.
Your batteries should NOT yet be approaching end of life;

C051414xxxxx
Manufactured May 14 2014

C091813xxxxx
Manufactured Sept 18 2013

As I recall, the screws are M4 ( metric ) cap screw, 30 mm
If you cannot find at your local store, there's always eBay like this;
https://www.ebay.com.au/itm/10xM3-M4...t/122705877050
( i have not used them, but hey for a couple of bucks how far wrong can you go )



Good Luck.

Our local WestLake Ace Hardware store has them.
