This refractometer from EZ Red allows you to check the precise state of your battery charge, helping extend the lifespan of your precious, expensive batteries. Simply place one drop of your batteries fluid onto the test window, peer through the eyepiece and record your reading where light and dark intersect the battery electrolyte scale. There are no batteries to replace, and no dials to turn so treat it with care and it will last a long time.
