Depending on how you want to use it, weight and capacity may be more important than cycle lifetime to you. LM339 has open collector output, and it needs a pull up resistor to drive the output high. The other cost would be to get an external 12v trickle charger, charge it until full (indicator). Avoid working near sparks and open flames. If youre testing the alternator output, the engine should be running. For example, if you have a 60Ah battery rated at 1C, this means that it is capable of delivering 60 A of current continuously in 1 hour. Putting the values; 168 13 = 12.92 or 13 hrs. Here you can find the schematic for the build and the board design that I created. During the load test the enclosure of the battery tester may become warm, this is normal. The higher the discharge rate (i.e., higher C ratings), the lower the total capacity of the battery. The opamp should have no issues at all driving it. The voltage should read greater than 12.6 volts and less than 14.0 volts. Load testing may be done either internally using hardware and software on your own network or externally using third-party test platforms. You should be recording the results of each of these readings as you go. Your local auto shop can load test your battery, but its simple to perform at home with only a digital voltmeter. Headlights are dim. Some battery load testers are able to give readings for all battery types. An alternator not only keeps your batterys charge topped off, it also supplies power to your vehicles electrical devices while the engine is running, so its a vital part of the system. Fully automatic testing. Remove the probes from the battery, black probe first followed by the red probe. Disconnect the battery from the system, remove cables and connectors, and clean off the terminals. Record what the voltage drops to. Be aware that if you do, some dashboard functions such as a clock or audio system anti-theft feature that require a constant charge will be disabled and youll need to reset them after re-installing the battery. A 12-volt automotive battery should actually read 12.6 volts when fully charged and the engine is turned off, and somewhere between 13.7V and 14.7V when the engine is running. Batteries swapped out, and did a load test with satisfactory results. Has it been sulphated by sitting around in a discharged state? Battery testers work by applying a load and monitoring the voltage response of the battery. USA Tel: 1 877 712 2278 | We suggest investing a little more, with reliable devices available for around $40. Load testers can determine voltage, and battery fluid testers often can measure both voltage and specific gravity. (See our policy) Touch the black probe to the battery's negative terminal, indicated by a minus symbol. When the energy starts to flow, its measured in amperes, commonly called amps. In practice, many battery load testers will provide a good deal more information. Connect the red probe to the positive terminal and the black probe to the negative terminal.
