Lead Acid Car battery to Alkaline rechargeable battery conversion

[bradw18]

has any one tried to convert a lead acid car battery to a alkaline battery? if so how did it preform.

That is like trying to convert coffee to tea.

why you say that? have your or anybody you know tried it? theres a couple good videos on youtube about it. i was wondering if anybody has ever tried it and used them on solar panels

There are many ideas on youtube - maybe even a few good ones if a person looks hard enough.

Alkaline Battery Conversion

This was I feel a rather less than appropriate response to the question. Successful conversions are done all the time. And although the result is not optimal as compared to the original lead acid design of that particular cell format, it is usable, and a great way to recycle continued life from your exhausted batteries. I have seen this type of conversion used for starting batteries service with good success, but not any research involving solar storage. Individual cell voltage is not identical to the lead acid configuration of course, but close enough to be usable none the less. I think that research into this idea deserves more merit, however you cannot expect the major manufacturers/retailers to be pushing against the existing format.

Actually alkaline based batteries account for 80% of manufactured batteries in the US and over 10 billion individual units produced worldwide. In Japan alkaline batteries account for 46% of all primary battery sales. In Switzerland alkaline batteries account for 68%, in the UK 60% and in the EU 47% of all battery sales including secondary types.

Think about your double AA's and 9 Volt batteries. If you look on the case you will notice that most are indeed alkaline based. This is pretty basic chemistry here. These are more optimized because they were designed from the ground up to be alkaline based. However the chemistry is not that far removed from what the original poster was asking about. Batteries are really a very simple chemistry equation. Making them super efficient is a much more complex endeavor. But simple bulk battery power such as lead/acid or lead/alkaline is very basic chemistry 101.

You are spreadıng BS - if you have any kind of back up (excludıng youtube) let us see it.

Only Edison Style Alkaline cells are rechargeable on any large power scale. Merely filling a Group 27 battery case with primary alkaline D cells, will work for a couple vehicle starts, but has no chance to work for more than a month.

There is the flaw in your logic PRIMARY CELLS. For solar or any rechargeable battery requires a Secondary Cell that can be cycled. Primary cells cannot be cycled to any usable degree. Only Nickel based alkaline (NiCd, NiMh, and NiFe) cells are secondary cells that can be recharged.

There is a reason you don't see any rechargeable alkaline car batteries. Ever wonder what happened to the rechargeable AA alkaline fad?

High internal resistance, high self-discharge, low cycle life. In other words, there is no point in doing a conversion to a battery that is worse than before.

No sane person would attempt to do this on a new battery, but by putting on an alchemist's cape and monkeying around with an old abused car battery, they may be able to get it to rise up from the operating table with a gasp or two, and light up some led's, or low power equipment as a goof.

I currently have a small bank of 6v golf cart batteries I purchased as scrap for $16 ea.

I desulfated first and got them into good condition. Then flushed cleaned and converted to Alcaline.

They operate very well. Voltage dropped at night. I have ran them down to 3v before and the work perfect.

Schneider electric has some nice controllers you can program the charging on.

I never have any problems with them. Currently running 8 for about three months.

They can easily hold amperage at 200 amps ea for 5-10 minutes and keep fighting all the way to 3v

i like mine quite well!
golf cart batteries have nice big plates.

i am currently picking up another 8 to restore. My long term goal is to have about 500-750 of them with 250 300watt quantum panels. I am going to build a new place and am planning the layout which will be ground based.

Batteries were my biggest expense before. Now I have dropped their cost to about 10% so it is possible.

Have fun with your new hobby keeping those door stops working for any length of time. Used batteries are usually one step from being dead weight.

And with 500 + all in one spot I would imagine the local EPA will come knocking at your door looking for your acid containment and waste disposal procedure.

What a moron.
