Sphero 2.0 battery replacement

- I tried the "woodpecker" method on my Sphero 2.0, but it did not crack open the shell, so I had to cut it open along the seam.
Before starting, I made a single black mark with a sharpie across the seam so that I could "register" and line it up again when gluing it back in place. I used a coping saw with a thin blade that fit easily into the existing gap, and made a relatively clean cut. (A hacksaw would probably also work well.)
After cutting, I sanded the cut sides down a little to remove stray pieces of plastic.
Replacing the batteries was relatively straightforward, but the 702035 batteries I ordered were definitely larger than the original '702035' batteries. Measuring the openings, I think they are closer to 30 or 32 mm long, so a 702030 or 702025 battery (if such a thing exists) would fit a lot better. I made it work with the use of a rotary tool.
I used standard CA (Superglue) to fix the two halves back together, and so far it is holding well. I had a clamp sized up and ready to hold the two halves together after I applied the glue to one side and used my black sharpie mark to align them.
After clamping, I rotated the whole assembly a few times just in case any superglue had gotten inside, trying to make sure that the interior robot didn't accidentally get glued to the inside of the sphere.
The sphere is very slightly smaller now (due to the cut material) but the interior robot "spring arm" assembly had plenty of slack and it doesn't appear to be having any problems in the slightly smaller sphere. But the gap between the two halves is much smaller now.

Bro you are a hero for me!
I changed the batteries still it won't work off the base
Looks like my 2.0 has died. Thinking about replacing the batteries, myself. What glue did you use to seal it back up? Not that it's a huge deal but would you guess that the waterproofing feature is gone?
Do you think you'll get a longer run time with the bigger battery?
I used regular CA (Super) glue to seal it back up. I don't know if it is still waterproof or not. (If I wanted to make sure it was, I'd probably paint the seam with epoxy after super-glueing it.
@@TheOne-TheOnly From a mAh capacity the batteries are not that much bigger than the original, just gave myself problems getting it to physically fit, so I'd recommend using smaller batteries than I did.
Okay, great! Thank you
Hello! I've just watched your video and really encouraged me to do it on mine. Is there any way I could get in contact with you besides the RUclips comment section? Thank you! Loved the video btw!
How does it behave on the charger once the battery is no longer good? I just bought the 2.0 Sphero on eBay and it was new in a unopened original box. I suspect the battery is dead from sitting unused for so long because I can’t get it to charge at all. The lights come on and charger blinks if it’s in the charger but after 3 hours it still will not come to life after detaching from the charger. Tapping doesn’t seem to do anything so it appears to not hold a charge at all. The only detail I find unusual here is that it won’t hold a charge for even a few seconds which I find strange for a brand new (though old stock) completely mint Sphero. Any tips for trouble shooting before I break out the coping saw?
That sounds like it's charging. Make sure the coil inside is visibly "flat/parallel" with the coil in the charger (if yours is one of the transparent spheres....). Normally if you put the Sphero in the charger and the internal robot bit detects it is out of alignment, it will move around inside to line up. But if the battery is fully discharged, it might not wake up to do that, so it is important you get them lined up for the charging to work successfully. I'd give it overnight (or, if you can't see the orientation inside, try turning it a few different ways over different nights) to make sure it won't charge up before cutting it open...as that's a lot of work. An ultrasonic cutter would make the job easy if you have access to one....I wish I did when I cut mine open.
@@summetj Great tips. Thanks. I’ll give it another try.
Hey! I have a few Droids of my own (and a 2.0) that I'd like to fix. What rotary dremel do you recommend?
I did not use a rotary tool for this one, I think a hacksaw or coping saw would give you a straighter cut.
Can you tell us the battery you used and where did you buy it ?
The specific batteries I used were purchased on ebay with the sales title of "2 pcs 3.7V 500mAh 702035 Lipo Polymer Rechargeable Battery For Camera Headphone" Item number 172428399373 (But the seller has updated the listing since I made that purchase). They were a little larger than I would have liked, so I don't recommend them, but I was able to make them work by folding the cell protection circuits over and stuffing things in. (See the description on the video for commentary about battery size and my alternate recommendation.)
its a shame and it shall be prohibited to sell this kind of toys with no chances for battery replacement, same should apply for phones, etc
I generally agree, although with the Sphero I understand that they were trying for 100% waterproofing.
@@summetj the problem is, batteries leak with time or can cause fire, so not being able to check battery status or replace it, is a mejor drawback specially for a toy. Also, makes the toy obsolte faster than what it should, if ever.
