So, to answer your question, Yes, 15 volts is too high. Most car alternators, that normally recharge your battery after every start, and provide power while the engine is running, are normally voltage regulated to about 13.8 to 14.0 volts. Up to this voltage and at normal temperatures, the battery will only gas very slightly. Above this, and it ...
Ok so I recently got my setup all done only to find out my voltage is a bit too high. The first few days of operation were pretty cloudy and falsely made me think everything was ok. When the sun is out I''m at 120v ish and the mppt on my growatt is only good for 60-115v. I was running a 3s3p...
When your battery''s voltage drops even a small amount it can make a big difference in its overall performance. For instance, a total voltage of 12.1 volts means that your battery is operating at only 50% of its total charge. …
At the moment I have the absorb voltage set to 58.8v, and yet, I still regularly see the battery voltage climb to > 60.0v (this with batteries at close to 20 degrees C, where temperature compensation will be a non factor). I still also see the S.G. climb too high if I''m not extremely careful. For example, during a cloudy period, I switched on ...
Yes, 14.8 volts is generally considered too high for a battery, especially if it''s a 12V battery. Most lead-acid batteries, commonly used in vehicles, have an optimal voltage range of 10.5-14.8 volts.
Basically, Nickel-metal batteries, when over-discharged, can grow little metal whiskers or "dendrites" between the internal plates, shorting the cell out. Applying a high voltage to the cell causes enough current to flow that …
Voltage of that cell, or even cells, can be too low/ too high or cell is (almost) dead. Often this happens with heavy discharge use. For example too much firewood cutting without any resting for many minutes. Cells can become hot and SDI protection kicks in and disconnects + pole of the battery permanente. Battery packs hate it to go low in voltage. …
