My content here is not really about cars but as most off-roaders love to camp overnight, I thought it may interest them. The issue is this: The wattage rating of LED lights, e.g. camping lights seems quite misleading on some claims on the net and even printed on the LED itself. Here I am referring to the rod mounted LEDs. If you go on to the net for LED camp lights it advertises ones of 800W and 2,000 watts for those shown in attached pics. As I was curious how long a 12V battery could sustain this LED light, things were not making sense . For some time now, I wanted to calculate how many hours my 12V , 7AH battery would sustain my camp light. My LED states it is a 100W light so it implied 8.3 Amps current . (using Current= Power/Voltage) . This means my battery would not sustain it even for an hour at the max 7 AH. However, it almost always lasts a very long time ( over 2 hours ) as I have never drained the battery during any of my late night picnics/bbqs. I could be wrong but I feel that these lights in specific are being rated as per comparable wattage not actual. The reasoning that led me to this is that if you buy an LED bulb for your home it would normally have a lighting level comparison stating its light output equivalence if you had an incandescent or an energy saving bulb that you were replacing with it. So a 13W LED bulb gives equivalent lumens of light as a 75W regular incandescent bulb and a 18-19W CFL. I request those into Electronics know-how to reconfirm my understanding.

This is now happened for second time yesterday in one month, that car failed to start. When we jump start car get started. In two weeks back issue car interior lights was getting on but not starting. In yesterday incident car interior light and door ting ping also not working, completely dead. When I jump start the car and drive for an hour and leave, car works perfectly fine and start also fine next day. Is the car battery getting old or something is draining the battery out in long stop for over 3-4 days. In both instances this was common that I started the car after 3-4 and 5-7 days gap. Please help.
