SSG-No Bloody Secrets

[Farmhand]

Yeah the single battery desulfator is a very useful setup (I imagine) I never built one, I've got a bank to power from that is solar charged so never thought it necessary. I think for a single battery setup the battery needs to have some decent voltage to begin with. Much easier to use a good 12 volt battery to power the unit from, at least for me. If I was to build a single battery setup I think I would use the 555 as well, since over charging is impossible and the part is much cheaper than a picaxe chip.

The SSG is kinda just a Boost Converter but without any smoothing caps and a battery as the load.

Similarly the So called "Tesla Switch" is just a pair of 12 volt batteries in series powering a load and 2 x 12 volt batteries in parallel as part of that load, then all flipped about. The Tesla switch can also work to increase the capacity of sulfated batteries.

Basically any way current can be made to flow through the sulfated battery without overheating it will do the job, I consider the proper discharging of the battery to be part of the desulfating process, so just using a partially sulfated battery as much as it will allow will in most cases bring more capacity to it.

For a lead acid battery ( especially Starter batts) it is very important to immediately recharge a depleted battery fully then rest it and don't discharge it too deeply. It's not good to leave a starter battery for a long period after discharging.

Right on all points.  Lead acid battery manufacturers are adamant that they must not be left in a discharged state. 

Clouds passing here or there may be enough to keep your solar bank desulfanated.

I bought this charger from amazon.  It does a pretty good job for charging and desulfating lead acid batteries.

Also,  what do you guys think about the new Tesla Home Battery ?

It looks like a decent charger.  The numbers on the Tesla Home Battery do not make it look very attractive to me.  In a few years if they get the cost down in half and net metering goes away then it will be attractive to people with solar installations.

I agree with what Tinman has shown here.

My SSG using 2 new motorcycle batteries really cranked out the rpm's.  I was thrilled with it.

BUT, after several battery swaps (charging battery/run battery) it would not work well anymore.  I stuck both batteries on a
standard battery charger and...I could never get them to come back...at least I got the core charge back when i turned them in.

The only thing I did not try was to use supercaps instead of batteries.  In my other experiments, it appeared that these capture high spikes really well and probably in a more efficient manner than those lead acid bats.  I might get around to trying this one day, I don't know if anyone has done this yet but...
I am not getting my hopes up.  My guess is that they will last longer and for more cycles than the bats but...eventually, more energy will have to be added from an outside source.
