Here's a product that I just stumbled across that may be of interest
to those with large battery banks that are difficult to access:

http://www.batteryfillingsystems.com....asp?page=home

I have no experience with this system but it was recommended by
someone on a boating EMAIL list that I subscribe to, and looks like it
might solve a problem on my boat.

Basically it uses special replacement battery caps that are tied
together with plastic tubing and a remote filling device. Each cap
has a float valve which closes when the cell is full. They sell
different types of caps and floats depending on battery type.

It is being marketed to industrial and golf cart users but I can't see
any reason why it wouldn't work on a boat.

the golf cart box. Then I had to slide the 8D out of its hole under
the shelf and horse it up out of the engine compartment. Not a fun
job, and I ended up giving myself a mild case of tendonitis in my
right elbow.

My theory (thus far unproven) is that an automatic watering systems
would allow me to take better care of the almost inaccessible 8D and
get better life out of it. The tubing for the plumbing system looks
like it is quite thin and should exit out of the existing cutout in
the battery box. We'll see. First I've got to finish some other
projects and then find out how much these fancy battery caps cost.
The tubing and filling arrangement should be very inexpensive.

The Rolls hydrocaps are nice but I don't know if you can get them for
a standard 8D. How much height do they add?


The weight of hydrocaps is negligible, AFAIK. But I have to ask, will your
remote watering system also measure specific gravity?

KLC,
Is it possible to get these hydrocaps for Trojan 6 volt batteries?

What is their function?

Regards
Peter Hendra

I believe that hydrocaps can be fitted to any flooded lead-acid battery, but
I'm not an expert on the subject. Their function is to recombine vapor into
liquid so that it doesn't outgass from the battery. Rolls-Surrette either
makes or carries them, they may be available from other sources.


KLC

Thanks very much. I'll do a web search and see if I can obtain them
here. I've never seen them. I have to replace my 4 Trojan 6 volts
after 7 years. My Areogen wind generator shed its blades and
consequently, after 10 months on the hard, the fluid level was way
down due proably to the heat here in Trinidad. I had to top each cell
with nearly a litre of water. They were due for replacement anyway.

Thanks for the response

Cheers
Peter Hendra

The only complaint I have is the ridiculous cost for some molded
plastic

"Large battery banks that are difficult to access" sounds like a
serious problem, at least on a boat. What do you do when it's time to
replace 'em?

Also, with all of the plumbing, etc, how do you get the lid back onto
the battery box? Cut some additional holes?

(I use a hydro-cap on my Rolls batteries, does a lot to prevent loss
of electrolyte),

Funny you should ask about replacement since I just had to do that.
It was a heavy duty 8D weighing about 130 lbs or so. It's installed
back under a shelf in the engine room which makes checking and adding
water difficult. To make matters worse I've installed a bank of 4
golf cart batts outside of the 8D in their own custom box with a lot

What kind of a charger are you guys using when on shore power?
The ferro-resonant types can really cause a lot of electrolyte loss.
The dedicated batteries for the thrusters on my boat (Navigator) used to be
tied to the old, FR charger and they were in need of water almost monthly.
For other reasons ... I bought a dedicated, dual output, 3 stage "smart"
charger for them and I now add a small amount of water once a year, if that.
The batteries are always being maintained by the smart charger.

I still have 3 8Ds that are charged by the older charger and they require
regular water replenishment. If I were going to keep the boat, I'd consider
investing in a smart charger for them as well.

Might be worth considering on the GB, though.

One of the major reasons I used the Rolls 8D, (aside from a 10 year
warranty wiht the first 7 not pro-rated) is that they are so super
easy to install and replace. You never lift more than about 30 pounds
at a whack, as you bolt 6 2-volt cells together inside a battery box.
If your 8D's are in a tough spot, it's a lot easier to swap them out
in 30-pound increments than making an awkward reach to try and lift a
couple of hundred pounds of battery. Why put the chiropractor's seven
kids through college? :-)
