Abstract
A charge indicator for a battery includes a transparent inspection rod comprising an observation area at a first end and a tip formed by a conical reflection area at a second end. The charge indicator also includes a ball cage that includes a gas bubble collection channel beginning between the first upper channel boundary wall of the ball guidance channel and the tip, the gas bubble collection channel extending from the lower area of the ball cage to the tip and extending obliquely toward the top to the upper boundary wall oppositely to the adjoining ball guidance channel at least from the tip. The gas bubble collection channel has in an upper area of the gas bubble collection channel a plurality of gas diversion areas running to the outsides of the ball cage in the direction of the upper area of the ball cage, starting from a central plane level with the tip.
