I decided to ignore the warning that it wasn&#8217;t user replaceable and have a go at replacing the coin cell myself.<\/p>\n\n\n\n<p>Disassembly was easy enough, there are eight T10 Torx screws and they&#8217;re all the same length so no need to keep track of where they came from. One of the lower screws is set fairly low into the enclosure so you&#8217;ll need a dedicated T10 driver rather than a 1\/4&#8243; Torx bit. The only other trick is to peel back the &#8220;Brushless Motor&#8221; sticker at the back and &#8220;Tool Connect&#8221; sticker at the bottom back 50% so the two halves of the case will separate.<\/p>\n\n\n\n<p>But upon peeking around no coin cell to be seen! The Bluetooth module is a rectangular module above where the Li-Ion battery fits with the nameplate on the bottom but the top was filled with white potting compound and I feared the coin cell was within the hard potting mix. After some searching I found that this was the case and the following gives the part number:<\/p>\n\n\n\n<p><a href=\"https:\/\/peter-johnson.com.au\/DCF888B_Parts_List.pdf\">Dewalt DCF888B Parts List<\/a><\/p>\n\n\n\n<p>The part required is number 26 and simply labeled as &#8220;Module&#8221; with part number N559222. The only place I could find the part for sale was on E-Bay at $US58 + $US38 shipping and charges to Australia = $US96 or $AUD150 at the moment! The module has a 4-pin connector and would have been easy enough to replace but I decided to pass at that price. <\/p>\n\n\n\n<p>While searching I found a few references to people having problems with the DCF888 not operating at all with a dead Bluetooth cell. However in my case it continues to work well and with a Li-Ion battery installed I can connect and configure the tool so I think I can live without Bluetooth when the main battery isn&#8217;t installed.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Recently the Bluetooth battery status on my DCF888 impact driver was being reported as poor in the Dewalt Tool Connect app and then I noticed it wasn&#8217;t connecting anymore.
