    Battery PC Mainboard - CMOS Bios Battery Circuit

    I could imagine the CMOS Bios Battery circuits are quite similar on all recent mainboards. What does it look like and how does it work? Background: My mainboard started draining the bios battery (an ASRock H55M). I inserted a fresh battery with 3.3v. It only measured 2.9V when I removed it...

    Storage heater Make & Model?

    Hi all, I have been requested by a client to remove storage heaters, just wondering if anyone is able to identify a make/model from the pictures as on my last visit I could not see any information on them at all and obviously have concerns over asbestos. Or if anyone knows where they have...

    Storage heater fault

    Strange one today, storage heater was roasting hot at the top but cooler at the bottom. Tested all elements, was getting 23 ohms for each of them so elements are fine, but client complaining that it’s not as warm as it used to be. The charge control clicks on and off when turning, could it be...

    Battery Car battery replacement

    I have had an N-reg Cavalier in long term storage during which time someone has deprived me to the battery. I suppose I could get a replacement from a breaker's yard but then I would not know the security code and the radio would be useless. The guys that designed such units obviously aimed to...

    Battery Earthing and Battery supplied Inverters

    Hi All, When I heard reports on the radio of people not being able to run their gas central heating because of a power cut, it got me thinking. Is there any reason a gas boiler couldn't be run on an inverter and a battery? I was thinking there might be a potential issue with some ac making...

    Battery Omron scales battery drain. Where do I start?

    Hi, I have these Omron BF511 scales which notoriously develop a battery drain problem. Normally they are supposed to last a year but suddenly they start draining a set of 4 AA batteries within a day. I took it apart to see if it has suffered from water damage. And indeed it had. The water...

    Milwaukee Packout Storage alternative

    I’ve decided that I need a storage system as my bag is becoming overloaded. I have a Packout box currently which holds my 12v SDS, Combi, Impact and Saw. I know you can get the trolley system but it’s so expensive. Is it really worth the price? I have seen a Magnusson Storage which including an...

    Battery Mikita DC18RC Charger, 3.0Ah 18v Battery question?

    I am very confused by this charger. The yellow LED in on, Battery Conditioning. What does that mean? Battery is fully charged, I think after 30 minutes. The yellow LED is still on. Makita needs to provide better documentation. Their lead blower runs out of juice on high after about 15...

    Battery 9v Battery Backup in line with mains adaptor?

    Hi everyone, I have a Toro garden water controller. It is a 9volt system operated by two PP3 batteries. With age the very thin wires on the battery connection have broken. It is in a shed so I have changed the batteries for a 240/9v adaptor. Works great and saves a lot in replacement batteries...

    Hey all, a few questions! I had some old storage heaters that I've ripped out and replaced with oil filed electric radiators instead. I now need to wire them up using the existing sockets that were there. First thing is what's involved with converting to a normal energy supply from economy7...

    Battery Battery off-peak charging?

    I’m highly likely to swerve this one, but just wanted to hear some thoughts. Old guy at newsagents this morning saw my van and started asking questions. He wants to somehow use off-peak rates to charge battery’s overnight…. Then use the battery through the day to run the house. (Electric...
