![]() A plate block is a battery cell.Ī conventional starter battery consists of 6 cells connected in series, each with a nominal voltage of 2 V, which results in a voltage of exactly 12.72 V when the battery is fully charged. Together, a negative and a positive plate set form a plate block. Several positive electrodes form a positive plate set and several negative electrodes form a negative plate set. This electrolyte can be in liquid form (as in conventional wet batteries or in the enhanced EFB technology), in gel form, or bound in a glass mat (as in AGM technology for newer start-stop applications). The electrolyte is a mixture of sulfuric acid (H 2SO 4) and distilled water. The electrodes with different charges are separated by a separator bag. Negative plate: Like the positive plate, this also consists of a lead alloy and serves the same purpose.Negative plate: The negatively charged plate (active material) consists of pure lead (Pb), which is also immersed in an electrolyte.Positive grid: The positive grid consists of a lead alloy and is used to hold the active material and as a current collector. ![]() ![]() Positive plate: In a lead-acid battery, the positively charged plate (active material) consists of lead oxide (PbO 2) which is immersed in an electrolyte.Components and structure of a battery cell The reason for this is the lead plates in the battery cells. Weights from about 10.5 kg, up to 30 kg are possible. Many drivers become aware of the heavy weight of car batteries when they buy a new one. But how is a battery constructed and how does it work? Lead-acid batteries: Components and structure In addition to the starter motor, the spark plugs, glow plugs, lights and electronic applications all require electrical energy. I know mini relays can be rated at up to 40A, but for a 25A load, I would prefer to use a larger 70A relay, rather than a standard mini relay.The traditional function of the battery in the engine compartment is well known: Without the battery the vehicle cannot be started. Select a fuse and holder than can supply this current continuously. All fuses should be located as close to the battery as possible. You will lose only a couple of lights if a fuse blows. Individually fusing the battery feed to terminal 30 on each relay is a good idea. Also helps protect switch contacts from arcing. Too many electronic modules that could be zapped by a relay spike. I also suggest using relays with resistor or diode protected windings on all modern vehicles. Positive of switch circuit is usually connected to relay 86 and negative to 85. The heavy power wires can go directly from the battery to relay to lights, without have to go into the dash area. They also allow the wiring between the battery and light to be as short as possible. Not sure about the connections on the switches. If you are concerned about shorts in the switching wires to the relays, swap the 30A fuses for 5A ones and change the switch common supply fuse to 10A. Delete the fuses between the switches and relay windings. Suggest fit a 5A switch common supply fuse instead of the 30A fuse shown in the second diagram. Here is my wiring diagram i put together can someone who knows what they are doing please take a look and see if there are any issues? ThanksĪlso can I run them in a parallel or some kind of circuit to save excess wires?įirst thought was "way too many fuses on the switching circuits". I have 8 blue LED rocker/toggle switches that I want to use they are the 5 pin dual LED back light style. I'm using anywhere from 18watt LED to a 300watt LED Bar and several sizes in between mostly 27watt. So I am by no means an electrician so when it comes to wiring up lights i always have a hell of a time, so this time I decided to come here first! I am going to be adding a fair amount of new LED lights to my Cherokee.
