You can examine this video for a more thorough treatment on exactly how this is done. Observe the storage temperature level when determining the open circuit voltage. A trendy battery decreases the voltage slightly and a warm one raises it. Utilizing OCV to estimate state-of-charge works best when the battery has rested Epsom salt vs baking soda for battery restoration (24cyber.ru) a few hours, because a fee or discharge upsets the battery and distorts the voltage. The rate of batteries remains to climb quickly. The ordinary expense of lithium and lead acid range from $17k-$ 20k.
