Questions about Inverter batteries.

Go buy new batteries Your going to waste hours on this, along with stuff to do the job.

I tried this on some old batteries about 12 months ago, horrible job.
They lasted about another 2 months, then died again. Maybe I did it wrong?
I borrowed a Hydrometer to test them, just to get it right as well.

Lots of sites online will give you the right ratios, I think the Trojan etc site has all the info you need.

Have fun and be kind to the enviroment when you dump all that toxic gunk about

Are gel batteries used much in the DR? I replaced a bank of Trojan 105's with a gel equivalent on my (former) sailboat with a sophistocated charging/inverter system. They are virtuallr maintenance free, and last a long time.

You can buy them here but they are expensive.
If you can afford them, they are the best option.

And Counting...

AZB, sorry to say, but I think, you've neglected your friends. Batteries should never go 'empty'.

Good battery care seems to pay.

I equalize them regularly and only use 'aqua bidestillada' to make up for the water loss.
My first set of batteries ("Trace" - I found out later that Trace does NOT make batteries... ) lasted 5 years and 4 months!
By then they had accomplished about 1,900 cycles, as we use them daily to power our house for 22 hours.
Charging is done by a diesel generator (2 hrs./day).

Now I have a set of TROJAN T-105 batteries.
Let's see how long they last (almost 3 years in service so far).

Just a quick note, AZB.
As mentioned in another reply, if you are going to try to save them one more time, you have to replace the acid with the original acid.
Fresh acid would be the kiss of death.
Robert's suggestion is probably the best.

Batteries-- clean or buy new

an interesting thread. we have now 4 Trojan 105's. after reading all the prior posts about cleaning blah blah it seems we might budget ourselves for one or two cleans and then a replacement. under ideal conditions, how long can we expect to ask a Trogan or other battery to last? 5 to 7 years? maybe the gel is the way to go, but the verdict on longivity and maintaince is still out.

thanks for depressing me more guys. Now I guess I have to cough up 12k plus for 4 new ones. dammit, I hate buying new battieries. I guess I will give them a kiss of death, I mean I will chuck it anyway so it might worth a try (replacing them with new acid). Lets see if I can get 2 more months out of them.

Sorry, AZB.
I was in a rush before.
Let me explain this better,
The acid you now have in your batteries is the good stuff.
It carries part of the elements of your batteries in the liquid.
It'a chemical action.
When you use the batteries, the acid eats away at the plates.
When you charge them up, it replaces what it took from the plates.
If you were to put new acid in, you would have tossed away a good part of what makes the bateries work.
So you can forget it.
If you want to go to the effort, you can do the following.
You empty all your batteries into a large basin, then after they drip dry, rinse them out with regular water, shaking and banging tha batteries around, to dislodge all sediments possible.
Once you feel thay are as clean as posssible, let then dry completely, then refill with the old acid, do another EDTA treatment and top off with distilled water.
You may save them this way.
I have done it in the past, only I had a kid do the dirty work.
Some of the old batteries did recover.
Hope this helps.

What is the Spanish name for distilled water for the batteries

It's premixed distilled water and EDTA.

You'll only have to spend...........

$11,800.RD if you cart the 4 old ones down to carina's house in POP. I believe her blog stated that there's a guy that drives by daily to buy old batteries for $50RD!

AZB. I had some similar questions recently and found this website www.mpoweruk.com/life. The previous posters were all correct in their advice about the difficulty in trying to renew batteries. The website gives the methodology to retrieve the "memory". I was pretty impressed with all the information on this website about all kinds of batteries including the gels mentioned in one post. Good luck.

Regenerate and Save

We are regenerating batteries, What actually happens to the plates is that they sulfate . Sulpher Crystals build up and collect on the plates. 85% of batteries can be regenerated through electronic pulsing which removes the crystals from the plates. Some of what you see when you empty the electrolyte are these Crystals mixed with some of the lead that peels from the plates through deterioration. When you pour the electrolyte out , you risk this material getting "stuck" between the plates and shorting them out.

We have the pulsing machinery installed and working at a regeneration center in La Romana. And we have 3 more centers in the works . We have a website and literature if you care to read about it . Private message me.

Costs RD 650 per battery. So for not quite the price of 1 battery you get 4 batteries regenerated with at least a 1 year guarantee. We also sell, (When we have stock) regenerated batteries for 850 Pesos or 695 Pesos with a suitable trade in. We will evaluate your batteries no charge and tell you if it is possible to regenerate them.

Now, this is all assuming that there is no existing plate damage or casing damage but you should be getting more than 4 years out of any quality battery.

We are in the process of installing several centers around the country.

The battery Viagra is actually now called Battery BB'Agra and Freddy Multiservices in Sosua is the manufacturer. It is mixture including EDTA and we use it also in the regeneration process. They are ALSO the Agent for Battery Klinic in Sosua and will soon have a regeneration center open in the Sosua Area.

This is nothing new....... This pulse technology has been around for about 20 years. The equipment is manufactured in the Lone Star State and the company is very reputable. Is proven and works. It is used From Boats to the US Military. It is Used world wide.
We have done lots of batteries here on the island and everyone is happy with the results. You can double and with proper maintenance even triple battery life. We will buy Any Deep Cycle Battery testing Over 5 Volts for 100 Pesos ! Because we CAN regenerate it. And Sell it. S0 If you just don't believe then We will buy your batteries at our agents locations.

This is going to allow more people to buy batteries and allow people to buy more batteries. It will also help the environment buy extending battery use.
We hope to have a program for Poorer working Dominicans soon to allow them to have some sort of back up system in their houses.

The centers are called Battery Klinic. Watch for one near you ! 42 Are planned across the country.

I have decided to do a complete over-haul of my dead batteries. My batteries seem to be losing water and heating up, 3 are also swelled from the sides.
They become hot when they are being charged and the charger in inverter seemed to be always charging.
This all seem like bad news to me. Here is what I have decided to do.

I have dumped out all my water / acid from the batteries. Battries are almost 4 yrs old and have been treated with EDTA 2-3 times. I have used heavy dosages of edta to get 4 yrs out of them. I assume the acid inside is totally contaminated.
So after throwing away the acid, I washed the battery cells (3 holes) several times and the black gunk is still coming out. These batteries weigh like a ton. I broke my back but kept washing them with water; every time I drain the batteries, I see black water coming out. Inside one battery I saw fragments of plate stuck to make a short among plates. maybe this is why the battery was not charging up. I cleaned it well, removed the broken fragments from inside, but the black water keeps coming out.
This is what I have decided to do.
I disolved a heavy table spoon of EDTA in a cup of water and poured it inside each hole / cell. Then I topped it off with water. All 4 batteries were filled with regular water with EDTA solution in it. I left the batteries out for 2 days and nights so the sulfur can disolve and come off the plates. Then today I will drain all the batteries and again do a fill up / drain routine to clean the insides of the cells. Then I am not sure what I will do. I can either fill it up with distilled water plus battery solution or add some EDTA as well to the water. I am not sure at the moment. I am tempted to add EDTA to the new acid but I also think it might contaminate the acid solution, thus, degrading its chemistry.
Please give advice.

It's all for nought.
Having thrown away the old acid, you threw part of the batteries away and there is no chance they will ever work properly again.
Sorry to be the bearer of bad tidings.
PS: Even that dirty looking old black acid would have been ok to put back in.
