Thank you.** A: Absolutely, you may use it with any flooded batteries. **Q: What is the expected life span of the rubber suction bulb on this Hydrometer?** A: I have had my personal one for over nine years. This is Florida, humidity tend to be high and I clean it after every use. If you neglect it and leave grease or other residues on it the rubber will degrade and will not be able to do its job. It Depends on the care and environment where you operate. It is rubber after all. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Very good product *by on Reviewed in India 9 October 2024* Very useful product.
