RV’s With Big Batteries Now Have a New Watering System

Single point battery watering systems are fairly new in RV applications. I for one don’t enjoy the whole “battery watering” drill. One of the reasons I’m a full time RVer is because I don’t want to be bothered having to “water” stuff, especially my batteries! Unfortunately, it’s fact of RV life unless you go with alternative gas matte batteries which have their own unique problems. These systems have been in service on the regular sized 12 and 6 volt batteries but unavailable on the larger 4, 6 & 8 D batteries found on commercial type trucks and many motorhomes. I did a story on why you should use these systems here Battery Watering System: As far as I know, Tom Tomlinson is the only one selling these 8 D battery watering systems to RV customers. The new single point all in one snap-in coupler is unique because it is a coupler, valve, filter, flow indicator and Y-splitter all in one. This system equally fills each battery cell simultaneously without overflow because the individual fill caps stop replenishing exactly when the proper water level is reached. The fill caps also have level indicators so you can tell when you system needs more water just by looking at the caps. Just connect the pump to your quick coupler and put the pump into a bottle of distilled water and after a few pumps you’re done. You can read more about it at Tom’s website here RV Power Supply: I like how this system works because it’s both safe and easy.
