Admin...if this is the wrong place to post this please move and I apologise...

 

You don't need to add distilled water to batteries these days. I haven't looked at a battery since I owned a 1980 XJ6 ! I too am old and getting a bit decrepit at one year off 4 score years.

 

Hello Fraser, Thanks for the quick reply. Appreciated. Am also not too computer savvy !

Regards

Peter

 

I would rather say that not all batteries need to have distilled water added from time to time, but some

Unfortunately, nowadays there are some batteries that would benefit from a top up, but where the manufacturer did not provide any easy access to the cells anymore

Does the batttery have the possibility of opening the cells? Then it does not hurt to check the fluid level and top it up with distilled water, if needed.

Best regards,

Thomas

 

Have seen it carefully done before, had to remove the label.
To expose the caps, & carefully pry them out to get to the acid.

 

Good Morning Thomas, There was no obvious way of getting to the cells of that battery. So...the only place I thought might work is to try and pry out the center portion where the vent hose is connected but thought I would ask here first. At this point will not be prying on it.

If it's a liquid acid filled battery, the cells can be filled.
Use a small flat blade screw driver, to pry them out..
Some are three in one plugs, others are individual.
Look on you tube for a video that shows you.
How to use a stick welder, to charge your dead battery back to life.
First thing is to fill the battery with distilled water, after removing the plugs.
No luck with the old battery's that i tried with a friends welder.
Got the caps out with no issues, but the battery was just too small.
The welder a commercial one, was way too big, boiled all over the place.

 

Hello Wingrider, Had anothe close look,at the Battery where I could try to pry but did not want to hammer "prybar" too hard in case of breaking the top of the
Battery. Thanks for the fiollow up

They're maintenance-free in name only, because that's what manufacturers prioritize. Checking the electrolyte level once a year can extend their lifespan by many years, especially for AGM batteries. The holes are usually under the covers or stickers. It's hard to say how much H2O to add, but for an old 100AH ​​battery, about a liter of H2O might help /or better 50x50 mixed with electro/, but it certainly won't hurt. Hardly anyone does this because it's not very convenient in a car for everyday use, especially if you have to remove several things to get to the battery, but why not in an X350.

 

Hello Peter,

Thanks for your follow up. In my case I will not be trying to pry up anything I might break which will be "self inflicted". I do not need any "self inflicted" episodes......

I presume you want to add fluid because the battery is not holding a charge well ? So if the battery is basically no good - why do you care if you crack or break the top ? When I bought my first x308 a few years ago the seller had an authentic Jag battery that was only a few years old. He told me the battery wasn't holding a charge well and needed Acid added to it. I wasn't worried - I just went to Walmart and purchased their top AGM H8 battery for only $160, they are great batteries with a 4 year replacement warranty and Walmart has honored it in the past for me, even in the third year. BUT I also didn't want to walk away from a potential Jag brand battery - so I went to my local interstate battery to buy acid. The guy there told me modern batteries are maintenance free and almost never require fluid, he tested it and said it wasn't worth putting money into it. he said that modern batteries have thinner metal plates, it allows them to produce higher cranking amps (more surface area) but they don't last as long, and most of the underperforming batteries are from exhausted plates (cells) not fluid. I told him I wasn't going to buy at battery from him because I just bought one a few days before (the walmart batteries are the same as interstate but $100 cheaper) . He told me he would sell me the $28 fluid but he stood by that he didn't think it would do much

 

Peter post a picture of the top of your battery. Wingrider is trying to point out how to add water.

Hello "C", Will have to get the yougster over to show me how to do that. Once I am "trained" to do it, will post it.

thanks Peter
