So I'm on my 3rd battery in 7 years, 9k miles. Does anyone know if its worth prying these open and adding distilled water?
Yep, have it on a battery tender, except last couple of weeks I had to unplug it because i was doing work in the garage.I'm guessing it's not drying out. Do you use a float or trickle charger? The regular use of these things often lengthens the lifetime of batteries considerably.
