There's not enough current capacity to do anything worthwhile. The bubbles act as a "surface charge" as Solar Mike mentioned... capable of sensitizing a high impedance voltmeter, but NOT indicative of the kind of electron flow quantity "current", amperes" needed to do useful work. | |

As Nick T pointed out, most SOC instruments observe the effect of a calibrated load for accurate results. | |

| Jun 13, 2017 at 3:08 | comment | added | can-ned_food | You say “false voltage potential”, but either there is a potential somewhere or the meter is indicating erroneously. Perhaps you should say something like: the reading is not indicative of the voltage through the entire battery. | |
