Me permite reparar baterias indicando el nivel de peso del acido. Si deciden comprarlo cuidenlo mucho ya que tanto el pesaacidos como la botella son de vidrio. cuando los adquirí tuve que realizar el cambio ya que me llegó quebrado el pesaacidos.

Great product and its exactly the same as one I've had for 45 yrs. The old bulb got hard over the years of use and cracked and became none fictional.

The first time I ordered this item , we sent it to our customer as it is without checking and the customer informed me that the glass is broken . Unfortunately the return window had closed by then . Second time I personally received the item and opened it in front of delivery executive and it was in broken condition again in the same spot . This time item is returned and I am now ordering for the 3rd time . Item seems to be delicate and not upto the mark. Will update rating once item is received in okay condition
