Forklift batteries??
 
I'm doing research on a coach I intend to purchase in the next week, 94 WB
the current owner told me he replaced the house batteries with forklift batteries,
I've never heard of such a thing,
please give me some input or opinions.

Hans, there are as many different fork lift batteries as there are automotive batteries, well, maybe quite as many but lots and lots:) It all depends on the coach i.e., space available and needs. Happy coach hunting:D

Forklift batteries are robust. No problem if properly installed, wired, and with a "smart" charger system to maintain them.

6 volt or 12 volt? Size, series, number of them?

hansruys 09-17-2016 03:15 PM

Don't know what they are, haven't seen the coach ...yet,

but you guys have already told me what I wanted to hear,

doesn't sound like it is a "problem", more like an "upgrade".

Hans, read this. http://www.wanderlodgeownersgroup.co...ad.php?t=20363

Thanks for all the help and advice,
now that I've owned the coach a couple of months,
I've had the time to experience dry camping
and waking up to dead batteries a few times.
(my coach was parked for five years before my purchase)

After doing some research and some head scratching,
I was leaning towards replacing the entire battery bank
with Trojan Golf cart batteries,
I pulled the forklift batteries out (100lbs each)
loaded them in my truck and drove to the local battery supply store.

Before I purchased, I asked them to "load check" my cores.
Turns out that 2 of the 4, L16 (forklift batteries) were still good,
I guess the two "dead" batteries were pulling the good ones down overnight.

Since the Forklift batteries have twice the amp hours of the golf cart batteries,
I purchased two more L16 Trojans ($500)
bringing me back to a total of 4 L16 and a 8D starter battery,
I just checked the voltage yesterday
and after two weeks they are still at 12.7 volt.

Next step will be some solar panels,
just enough to keep the batteries charged up.

Not a good idea mixing old and new batteries. Even though the old ones load est ok, they will have different charging and drain characteristics from age and that is not good for he new ones. Do some research on the net and you will find more on the issues.

Im with Gardner. Not a good ideal mixing those battries. You don't do thatspelling in your flashlight, why would you do it in your coach?

hansruys 11-22-2016 01:53 PM

Well now Rick, if my flashlight batteries cost $250 each
I certainly would mix them :) but I get your point!

Thanks for the "heads up" Gardner,
I've been researching the subject and learned quite a bit.

Like anything else on the internet there are a lot of opinions "out there"
here's a link to another RV forum where (John from Detroit)
answered most of my questions.

At the risk of offending the purest among us, I would also choose to mix new batteries with good used ones. Yes it is not perfect, but it is also not "perfect" to throw away good batteries just because some of the them have gone bad. The LXI has 6 ea 4D's. If you replaced the whole set a year ago and then one has a shorted cell, you should replace all 6? I don't think so! Maybe the new battery would work a little harder than the other 5 for a short period, but I would expect soon it would fit right in. It doesn't make sense to throw away 5 batteries with 5 or 6 years of life left to keep from working the 1 new one a little bit harder for a while.

Battery and tire discussions are about the same. Combinations of facts and hear-say. As long as you do some research, understand the principals and keep an eye on things (preferably with eye protection) you should be fine. Specific gravity is a good method of determining how each cell is doing and can reveal issues that otherwise might not be apparent.

Could buy a fork lift, har!

That's exactly what I intend to do,
a hydrometer reading on every cell once a month,
the reminder is already programmed into my phone's calendar.

I'm not ready to throw away what may or may not be good used batteries,
I'll never be a "purist" but I am here to learn,
before this tread I had never heard of the "issue"
if there is a significant "difference" I may keep them as a "backup"
by adding a third battery switch to separate them,
Not sure, I need to think on that some more.

When battery get older its internal resistance/impedance increases, chemical properties changed so when a fresh battery added in old batteries it could not be balanced with remaining old batteries in the string and according to series resistance calculation every different value in string will get different charging voltage, hence could not be charged or discharged evenly, resulting reduced performance of whole battery bank.
