Hi Bob,
Thanks for the web site reference,I've checked it out and found it very informative.The specs comparison is usefull and confirm your recommendation so I'll follow up with them.The Aussie dollar being so strong makes it a good time to get a bargain.Cheers Rastus

Hi Rastus

I have found them very good and I haven't managed to smoke one up yet, that's unusual for me, I will be getting 4 more when finances allow to cover all the battery bank.

All the best

Bub and I have some of the 12 volt models here and been in operation a year or so and no problems with them.I want to get more when I get some money that I can spare .

Hi Bob & Isaiah,
There were testimomials on the infinitum site,however I dismissed them as dubious and concentrated more on the specs.Having feedback from a known/reliable source is more reassuring.Thanks guys.Cheers Rastus

Rastus//everyone,
I'll give the thumbs up to the desulphinator, no problems what so every with mine.

I have come to realize that keeping the battery terminals clean and tight is of importance in the longjevity of a batter's life and performance. Just because they look good and clean on the outside dos'nt necessarly mean they are clean and tight. A good connection is vital to getting and maintaining a fully charged battery.
If you don't dammage it to start with by dragging down the voltage, you'r ahead of the game. The desulphinator will help restore a damaged battery in some cases.

Bob and All,
Dose any one have information on making your own battery?
I looking for something to work as the old 2 volt 160 amp hr radio and farm light battery.
I have a old 6 volt wincharger and control panel and was thinking of finding a old battery radio to go with the system.
we recently can into a small supply of some stainless steel sheet metal and was wondering if we couldnt use that for the plates and a wide mouth fruit jar?
wal mart has 6 volt rechargeable battery a 2 pack for 17.99 us frn.but they are 4.5 amp hr.
probably better get a 120 volt radio and put a small inverter in line.
we did have some luck with several car battery's this summer and two marine battery's
no hi decibel events and the rectifier held in the old tungar this summer also.
has any one else had any experiences in battery rescue?? ''
We have herd some bad stories on some of the cheap battery chargers made in china with too much plastic in them, some didnt work right out of the box. better spend a bit more for a good charger. ''

Hi Charlie

Many years ago when I did my training one of the things we did was make a battery out of wood sealed with pitch, it used plates from good cells in damaged batteries, by using a few sets of plates in one enclosure we got a large capacity 2 volt cell.

I wonder if that is practical now though as there are many transistor radios available that are more efficient. Maybe use one of them with a gell cell for power.

The batteries I did in this thread are still going ok, however I have lost some of the SLA batteries, they do not respond as well as a full wet cell.

One place to look for large cells is a fork lift wrecker / service station as the cells are wet and good quality but if one cell in the pack goes out they scrap the whole battery.

Beware of Chinese Junk battery chargers as I have three of them catch fire, the last one nearly burned down my shed.

All the best

We had a friend get one of those china chargers and it didn't work right out of the box so he took it back and got another and it dosen't work right either.
I told him to get his money back.
The big lift truck battery's around here they do repair them and also have a scrap value of 750 to 1000 or more us dollars. That puts them out of my reach.
My son got hold of a 36 volter but we dont know what he will do with it.
the 36 volter has some voltage but the water is down in all the cells I looked into,
It may need some acid also. it was setting for some time.it showed 34 volts when he got it and he hooked a 36 v. golf cart charger to it and have the voltage up a couple volts, I think it should go to around 42 volts.
its getting on to winter so we need somethings to do inside. ''
I guess no one else rescued any battery's??
Well if we can save someone from a meltdown of one of those Chinese chargers its worth our effort!I think Mac46 had one go bad also

Hello isaiah and everyone,

No, I don't own any chineeze battery chargers...only USA models for me. I have succesfully cleaned up 4, 6 volt deep cycle batteries with the desulphinator and I'm still working on my two 12 volt dozer batteries...one is comeing back ok while the other one is being stubborn. Several other car and truck 12 volt batteries have been cleaned up, had them tagged in along with the deep cycle ones. I lost one 12 volt battery that was in the tractor, it was only 2 years old...Murphy's way of evening things out I think.

I've been researching "how to make battery's"...Granddad's tools and plate molds are gone, no one knows anything about the stuff. I asked 50 years to late I guess.

Mac46 and others,
Bub found this link, lots of battery info there.might be good to copy it.

http://www.powerstream.com/1922/battery_1922_WITTE/batteryfi les/chapter17.htm
maybe if we can find the equipment we could work together on a battery project?
we do have a pile to go to recycle we may be able to salvage plates etc.
Probably need a rubber apron and boots.
MAC46 Glad to hear you had some success, one of the ones we rescued I used on a pontoon boat I was given this summer.Ive got two deep cycles and 3 or 4 car battery's Im going to put in the basement for winter soon, We got a good frost all ready tonight.

Isaiah

isaiah,
(probably need a rubber apron and boots)
apron, boots, and most important ...Face shield, not to mention gloves and neutralizer just incase, and a shower or a source of water for a quick flush.
I have "his book"... A O White, so anything about everything is in there as far as batteries is conserned.
yes, colder weather is comeing...lots to do before winter gets here.

Any body have any luck rescuing any battery's one of the big tractor battery's mentioned a few posts back is still going strong.
There may be some newcomers out there so dont be afraid to ask questions here.

Hello isaiah,

Just for an experiment I hooked up a small battery from my lawn tractor..."one of the old ones that have been setting around for a few years", and to my utter surprise it has recovered. I've put it in the lawn tractor just to see if it will continue to function, and if so, for how long.
Desulphinators won't bring them all back by anymeans, I'm haveing about a 50% success rate with mine...and have had it almost one year now. I'm includeing the old batteres that have internal shorts and also the one battery that is testing "open", with my 50% average. I have paid for the desulphinator by the batteries I have put back into service.
regards,

Mac46

Hi All

My experiments have proved the rescue can be done and most batteries revived providing there are no mechanical issues, the ones i have had the least success with are the SLA type as i have found that they do dry out over a period of time and with no way to establish the amount of water required to top them up, also as they dry out the plate deteriorates from the top down and is damaged beyond repair.

I have revived gell cells from 0 Volts dead to 80 %capacity but no such luck with SLA
I have come to the conclusion that the so called maintainence free batteries are not ideal for long term usage, the old style wet cells win hands down.

All the best

Bob

Well its good to see the battery posters are still around and doing well!
maybe some new eyes will come on board here.
I had two marine and three car battery's that were rescued. its getting harder to find used ones to rescue.

This last week end I picked up 4, 6 volt battery's that were setting about 8 months and just over a year old .
I brought them home and put the Tungar on them one at a time
and they have came up good and the gravity test is good on them.
At this time Im using them as a battery bank on my mill test stand
looks like I made a good buy there.
I put a wanted add on Craig's list in the wanted section and got several results.
One junk buyer contacted me and said he gets lift truck battery's
every couple months so there may be some possibilities there.
Any body else have any luck rescuing battery's??

Hi norcold,
Checked out the battery university,..restored.I'm obviosly biased,I feel the specific test data on this thread has better,more practical content.Did tell you I'm biased didn't I? Cheers Rastus
