It is a matter of habit, more than a matter of science. Hope you can help This worked perfectly. I was interested most in the little device that attaches to the battery says it slows down the sulfation process. To get 200mA charge you need to put something around 1000W in series with the 12v battery charger - The 60w bulb will give you only about 8mA . I think you may be causing the inverter control circuit to become confused by the way you are switching the system. If you already purchased the battery, keep it charged, discharge it as little as possible, keep it from overheating, keep the demand low (typically 1/10th current drain of the battery capacity), keep the the cells filled, topping up with distilled water as needed, and monitor the electrolyte density of each cell to be the same and equalize the cells that are under by overcharging occasionally while keeping an eye on electrolyte level and refilling those cells that are drying up in the process. In other words… No doubt Li-Ion is better for your application, it’s simply a matter of figuring out whether to purchase the pack or get into the adventure to make your own. He also did little or no fluid maintenance. It might take a day or two or maybe more to charge the battery in reverse until it reaches around 12V and holds its charge. And what should be the maximum peak of that pulses, would that be related to battery capacity or voltage? There are many, many ways to achieve the proper excitation….the key is in the application and the algorithum’s being used to maximize the effects. So far, my solution looks pretty good to me and I am hoping it will be found to work well. That would mean that if you try to regenerate a UPS battery, you are almost dead, on the contrary you can find a solar battery completely sulphated. Im not “happy” to bring the battery in—but I think it may be the most workable solution for me. I know you have suggested using a basic transistor rectifier charger for the job of maintenance but that doesn’t corrolate to battery charger makes and models. Reverse osmosis and deionized water can be purer than distilled water. Cadex Electronics Inc. Connected 4 in series with these in parallel with four others to create a 48 V system. It began reading high after a couple of years and I changed the battery. If that is not possible, caveat emptor. my 1year old inverter battery undergone a deep discharge when i didn’t used for a long time i want charge it again how much it will cost? ), in your setup the resultant sulfate will be much different then if you actually replicated a real application. loss’‘. Is this an inferior approach? Regarding float charge, you asked: Where is the 0.1A going? Carry on searching, corporate names, via popular search engines and a world of useful information becomes available. (looks like, but isn’t actually 3 car batteries) the scooter goes up to 25mph and it’s range on a full charge is 10-18(obviously depending on the speed and terrain driven on). I didn’t deal with the charger other than to monitor one charge after my repair job, but it didn’t seem to pay any attention to the notion of bulk and absorption. The first cell must therefore give a different, although not necessarily bad reading. There are only two possibilities. Giving an agm a high voltage equalizing charge is a to damage it. Eventually the battery does not accept charge, does not deliver amps. This isn’t nuclear physics. Temperature Correction Sure the battery is charged up past 15V. If you have a suggestion or would like to report an error, please use the "contact us" form or email us at: BatteryU@cadex.com. If the person who made the point actually has a valid point, the second concedes. John, what was it that you introduced to the battery that reduced the water consumption? However, how can cell 1 read so differently if Khurram is measuring series voltage?
