Fixing Sonos CR200 charging issues

I have two Sonos CR200 (aka Control) units in use with my home Sonos system. I love them, no Android or iOS client can match comfort of those dedicated units.

Symptoms

Recently both of my CR200 started to act up, battery was always low even if they where left in the cradle for days in a row.

Reasons

Since my remotes are quite old I suspected battery first and order replacement but that did not help. After some research I discovered that contacts in CR200 charging cradle are gold plated and get worn down with time, decreasing contact conductivity.

Solution

You can get new cradle from Sonos or just replace stock 5v power supply with 6v unit. I used 6v 2A power supply. All remotes now charge happily, so far I see no adverse side effects, battery does not feel warmer then before.

Because of proprietary form, you will need to re-use connector from Sonos charger on your 6V power supply. Be careful with polarity, (+) is center.

London — Two Jewish people were stabbed in north London on Wednesday, witnesses told CNN, in an incident that comes against the backdrop of a series of antisemitic attacks in the UK capital.
A 45-year-old man, who is also accused of trying to stab police officers, was arrested on suspicion of attempted murder, the Metropolitan Police said in a statement.

Counter-terrorism officers are leading the investigation and working to establish the suspect’s nationality, background and any terrorist links, police said.

Two men – one in his 70s and one in his 30s – were injured in the attack in Golders Green and are in a stable condition in hospital, police added. No officers were injured in the attack, which police responded to at 11:16 a.m.

A man armed with a knife was seen running and “attempting to stab Jewish members of the public,” according to Shomrim, which provides local neighborhood watch and emergency responses. The group added that it responded immediately, and that police deployed a taser once they arrived.

Large swathes of the road had been cordoned off by police by the time CNN reached the area, and several emergency service vehicles, including an ambulance and police helicopter, were in attendance.

Police put up crime scene tape near the scene of a stabbing in London on Wednesday, April 29, 2026.

London’s Jewish community has been targeted by a wave of antisemitic attacks in recent weeks.

Last month, arsonists set fire to four ambulances belonging to a Jewish charity in Golders Green, north London. Four people were subsequently charged by police.

Then, weeks later, a synagogue and the former premises of a Jewish charity, both in north London, were attacked.

UK Prime Minister Keir Starmer described the “antisemitic attack” as “utterly appalling.”

“We all need to… be absolutely clear in our determination to deal with any of these offenses, the like of which we’ve seen too much recently,” he told parliament.

Russia on Tuesday test-fired a new intercontinental ballistic missile as part of efforts to modernize the country's nuclear forces, a launch hailed by President Vladimir Putin just days after his claim that the fighting in Ukraine is nearing an end.
<a href=https://slon5at.net>slon7 at</a>
Putin said that the nuclear-armed Sarmat missile would enter combat service at the end of the year. It was built to replace the aging Soviet-built Voyevoda.

"This is the most powerful missile in the world," Putin declared, claiming that the combined power of the Sarmat's individually targeted warheads is more than four times higher than that of any Western counterpart.

The Russian leader has repeatedly brandished the nuclear sword after sending troops into Ukraine in February 2022 to try to deter the West from ramping up support for Ukraine.

After overseeing a military parade on Red Square on Saturday commemorating the defeat of Nazi Germany in World War II, which for the first time in nearly two decades didn't include heavy weapons, Putin declared the conflict in Ukraine is coming to an end.
<a href=https://at-slon5.cc>slon7 to</a>
Since coming to power in 2000, Putin has overseen efforts to upgrade the Soviet-built components of the Russian nuclear triad - deploying hundreds of new, land-based intercontinental ballistic missiles, commissioning new nuclear submarines and modernizing nuclear-capable bombers.

Russia's effort to revamp its nuclear forces pushed the United States to launch a costly modernization of its arsenal.

Nuclear arms pact expired
The last remaining nuclear arms pact between Russia and the U.S. expired in February, leaving no caps on the world's two largest atomic arsenals for the first time in more than a half-century and fueling fears of an unconstrained nuclear arms race.

That same month, the U.S. and Russia agreed to reestablish formal, high-level military communications that were suspended in late 2021, prior to Russia's full-scale invasion of Ukraine.

The Sarmat — designated "Satan II" by NATO — is meant to replace about 40 Soviet-built Voyevoda missiles. Its development began in 2011 and before now, the missile had only one known successful test and reportedly suffered a massive explosion during an abortive test in 2024. A satellite image analyzed by CBS News at the time showed a large crater and remnants of a possible explosion on a launchpad at Plesetsk Cosmodrome in northern Russia.

The Sarmat is classified as a "heavy" ICBM and is capable of carrying up to 10 tons in payload, according to the Center for Strategic and International Studies' Missile Defense Project.
