hydrometer recommendations
I use Interstate GC2 6 volt batteries in my camper with a remote water filling system. They've been in there for 4 years now and I figure I should probably test the specific gravity of the cells befo...

Battery manufacturers choose Freas. They are -absolutely- accurate, have a PYREX instead of glass tube.
RINSE RISE RISE after each use. Fill the tube and bulb with fresh water. This keeps the bulb and siphon tube from developing cracks. I have seen NAPA hydrometers with .08 error. That I do not need. EZ RED dial gizmos are worse.
I went to Home Despot and purchased black PVC pipe, a cap for one end, a tube to threaded bushing for the opposite end, then a threaded plug with male square tip to grip and unscrew. The rubber bulb and rubber flange protects/cushions the Pyrex glass tube. This setup can take an incredible amount of abuse. The cap and bushing fit are so tight I didn't even have to cement them.
Bobbing balls and whirling discs are for suckers for gizmos. A Freas will last 100 years.
Remember the WEAK SISTER CELL trick. Find the weakest cell then pick on it. It saves an enormous percentage of dipping time. I "waste" oh, what, 3 minutes a week? When I could be doing something valuable like coping with boredom.
