Basic to Advanced Battery Information from Battery University. UPS Battery - sealed AGM batteries. Guide to Understanding Flooded, AGM, and Gel Batteries. If you have done any research on how batteries work or what you should look for when selecting a battery, you are probably buried in information, some of which is conflicting.
At BatteryStuff, we aim to clear that up a bit.You have most likely heard the term K.I.S.S. (Keep It Simple, Stupid). I am going to attempt to explain how lead acid batteries work and what they need without burying you with a bunch of needless technical data. I have found that battery data will vary somewhat from manufacturer to manufacturer, so I will do my best to boil that data down. This means I may generalize a bit, while staying true to purpose. The commercial use of the lead acid battery is over 100 years old. If you can grasp the basics you will have fewer battery problems and will gain greater battery performance, reliability, and longevity.
Power Managemment Solutions, Inc. The following four factors determine the lifespan of a UPS battery: Battery Life: Design Life vs.
Actual Life Determining battery life can be a tricky business. Battery life is often promoted based on design life, that is, how long the battery can be expected to perform under ideal conditions. Estimating actual battery life relies on taking into consideration the four factors that can impact battery life. Batteries have limited life, usually showing a slow degradation of capacity until they reach 80 percent of their initial rating, followed by a comparatively rapid failure.

The term is typically used to specify a battery's expected life, as the number of charge cycles affects life more than the mere passage of time. Discharging the battery fully before recharging may be called "deep discharge"; partially discharging then recharging may be called "shallow discharge". In general, number of cycles for a rechargeable battery indicates how many times it can undergo the process of complete charging and discharging until failure or it starting to lose capacity. Apple Inc. clarify that a charge cycle means using all the battery's capacity, but not necessarily by full charge and discharge; e.g., using half the charge of a fully charged battery, charging it, and then using the same amount of charge again count as a single charge cycle.

Magnum Energy Inc. Motobrain. Motobrain: High Tech Automotive Power Distribution Unit by Joshua Oster-Morris. The Motobrain PDU (power distribution unit) is a next generation, high tech, fuse block and power distribution unit for use with 12V systems.
The system will control a wide range of electrical accessories on your car, truck, jeep, motorcycle, boat, or whatever you can think of. The device is solid state and Bluetooth 4 enabled, so you can control the entire system from your Bluetooth 4 equipped phone or tablet. We currently support iOS devices and will support Android 4.3 devices before delivery. Solid state construction means you can digitally set your current limits without the need for physical fuses or breakers. Circuits can be controlled with our proprietary input interface which allows you to logically connect PDU outputs to existing vehicle circuits or hardware switches so the phone is NOT required for daily use. The device can be used to control many different auxiliary electric devices in automotive-type environments. Absolutely not! Features – Real-time Telemetry – Timeline: Free Charge Controller - Free Charge Controller. Lead-Acid Battery Charger Monitor. As per manufacturer’s data sheets, a 12V rechargeable lead-acid battery should be operated within 10.1V and 13.8V.
When the battery charges higher than 13.8V it is said to be overcharged, and when it discharges below 10.1V it can be deeply discharged. A single event of overcharge or deep discharge can bring down the charge-holding capacity of a battery by 15 to 20 per cent. It is therefore necessary for all concerned to monitor the charge level of their batteries continuously. But, in practice, many of the battery users are unable to do so because of non-availability of reasonably-priced monitoring equipment. The circuit idea presented here will fill this void by providing a circuit for monitoring the charge level of lead-acid batteries continuously. First, it reduces the requirement of human attention by about 85 per cent.Second, it is a highly accurate and sophisticated method. 12 Volt Battery Monitor Circuit with LM3914 - Storage. Accurately monitor battery voltage with LM3914 LED bar graph driver home > storage | electric circuit | educationIn our article Make a Simple Battery Status Monitor we showed how a few components could be put together to make a very basic battery voltage monitor to give a visual indication of the charge state of a 12V lead acid battery.
Here we will show you how to make a more advanced battery monitor using 10 LEDs (or an LED bargraph display) and the LM3914 dot/bar display driver (pictured above) to show the battery voltage very accurately. (Click here to buy an LM3914 Display Driver from around £1.50 each, and here to buy a 10 LED Bargraph for around £2.) 12V Battery Monitor Circuit Above is shown the schematic for our 12 Volt battery monitor.
To calibrate the monitor, connect it to 12.65V and adjust the 10K potentiometer (VR1) until the last green LED turns on. The LM3914 has two modes - DOT and BAR. In DOT mode the circuit shown above would draw under 10mA. More Information.
