Guide to Changing the CR100 Battery

Thanks for this guide. I got a new battery off ebay and changed it easily thanks to this guide. Works a treat!
Thanks a lot!

After purchasing replacement batteries on eBay, I replaced the batteries in all three of my CR100s and bent up the metal tabs inside so they make contact again.

My controllers now all charge in their cradles and hold a charge!

The adhesive holding the blue backing on my controllers was completely dried out, so I used some Scotch "Permanent Double Sided Tape" to re-affix them. I can tell they're probably going to come loose in one or two places, so I'll probably follow up with some higher quality double-sided tape. Other than that, this worked like a charm. Thanks!

Brilliant, a snap, thanks!!

Hi cnewlander, I used your excellent pictorial guide to replace the battery in my cr-100 controller. All went very well and the new battery was fully charged when I switched it on. Unfortunately, the battery has never taken a charge since day one although it indicates that it is charging when in the cradle. It's a real bummer. Any ideas?

Welcome to the forum.

Does it charge if you plug the charger directly into the CR-100, bypassing the cradle?

Found a battery on eBay for $17 and was able to replace it easily. I agree that you don't need to remove the entire blue pad, just lift it up directly over where the screws are and just enough to get the screws out. I used a black Sharpie pen to put a dot over the screw holes to make them easier to find on reassembly.

On mine the gasket came out attached to the body, not the cover so I had to carefully work it back into the channel around the cover.

The wires to the plug on the new battery were quite a bit longer than the original, so I folded them back and re-used the clear yellow tape to hold them in place.

Thank again for posting this HOWTO!

I finally got round to replacing the battery in one of my controllers from 8 or 9 years ago. The battery retention had been very poor (a few minutes) for a while, but recently it stopped working altogether. With the battery now replaced it is great again.

I too managed to lift the blue only where the screws where, it has gone back easily. My guess is in one place I will need a little glue eventually.

The screws are quite soft I slightly damaged one using a screwdriver that was the wrong profile.

I'm in the UK and bought my battery from Amazon UK before I opened the controller so I didn't need to worry about glue or gaskets drying out.

Like the previous poster my wire was a little longer than the battery being replaced, but it tucked under the connector quite easily.

A good result for £11.

this week i replaced the battery in my 9 year old CR100. To confirm how old it was i took a quick look in my email, wow how time flies. i pre-ordered my sonos bundle 11/28/2004. crazy...

anyway, my CR100s both died many years ago. we moved on to ipads and iphones. however i was kinda bored so ordered a battery, followed these instructions and the original CR100 is back!

i missed it. i like the dedicated device and still modern feel of it. it might be nostalgia.

the replacement on the first went perfectly so i just ordered another battery to repair its fallen brother.

thanks for the info in this thread.

Thanks again for this guide. I just replaced the battery in my other CR100. I was again able to only lift the blue mat where the screws are. The replacement battery (from eBay) had the longer wires to the connector, just like the first one. The orange gasket was much better behaved this time -- it just stayed in its groove. The old battery was stuck much tighter, so I had to carefully cut the adhesive to get it out.

Many thanks for the guide. Helped me to replace a very worn battery which was only holding charge for 1-2 minutes.

Great tip to only peel back the corners/edges to access the screws rather than the whole rubber back.
