Excellent idea, will do it.
Thank you all for feedback!
No, don't do that. The battery in your car does not need to be re-engineered, not even a little. Battery vents do not leak fluid, unless the battery and/or the car is upside down. Everyone who has suggested that you check the charging rate has given you excellent advice.
Make sure you check it properly.
