Hello, was wondering if anyone is familiar with this problem. The LED tubes in garage and LED bulbs in bathroom (all on the same circuit) blink in a regular and reproducible pattern. By "blink" I mean the intensity apparently goes noticeably up for just a short fraction of a second, high enough to make it annoying and hard on eyes. They do it even when nothing else is on in the circuit. The pattern is: fourteen blinks about once every second, that is at about 1 Hz, are followed by 24 sec of normal light, then again fourteen blinks about a second apart, then again 24 sec of uninterrupted, normal light and so on. Has anyone experienced this? Is the problem in the LED lights or in the circuit wiring, or in the appliances on other circuits, or in the city line? I can't exclude the city line or connection to the main because we've had loose neutral, loose phases several times before after strong winds (right now it's about 30 mph). Any comment will be greatly appreciated. Best wishes, h. ​​​​​​

I have a little project planned. I am making a toolbox into a boombox out of an unused car stereo . I do not have any of the major parts yet, basically so far I only have the toolbox and a few SLA batteries that I though were good but I guess I let them sit a little too long. So my stupid so called "smart" charger does not even attempt to charge them. It is a [url=https://www.ebay.com/itm/184292583216]ChromeBattery[/url] Xtend 6 step 4.2A probably not the best one of these out there but it is all I have (for now). I have 1 18AH 12V SLA that measures only 7.08V So I think that one is a lost cause unless there is a way to revive it but I don't think so I also have 2x 7.2AH 12V one was at 12.13V and the other one was 11.95V. The 12.13 one charged fine but the other one the charger said it was a motorcycle battery and took about 3 hours and then switched to the car symbol (higher current I guess). It did fully charge it though it just took awhile So my question is there a way to get it to charge the 18AH one or is it a lost cause. Also I am going to put a heavy duty switch on the red ignition (Key on/off) switch. How much current does the [url=https://www.crutchfield.com/S-dFpB54yHMAk/p_113BT772HD/Kenwood-KDC-BT772HD.html]radio[/url] need when the switch is (key out engine not running) off when just the yellow wire is connected to the battery. Also how does battery wiring work? I know if you wire them in series you get twice the voltage (24V with 2x 12V) which I don not want to do as that would instantly fry the radio (and that would be the end of my project) If I wire them in parallel I get twice the capacity but still 12V? So if I wire both of those 12V batteries in parallel I would get 12V 14.4AH? or am I wrong? I obviously want a decent running time. I probably will use mostly in the house (for that I have a heavy duty power supply for) but I want it to be portable at the same time (not simultaneously of course). Thank You and good job if you got this far :coffee:
