Submarine Batterys

[peakbagger]

I was looking for something else and this listing popped up on Ebay

http://www.ebay.com/itm/14-kWh-Batte...-/301941299859

The care and feeding of a battery bank of these would be pretty interesting!

I am not sure what a single 2.1v battery will be able to do for anyone even if it is rated 7000Ah. You would need 6 of them to make a 12.6v battery system and maybe a reinforced concrete floor to keep them from dropping into the ground

He claims to have a lot of them. 30K plus freight for a 12 volt battery with really large bus bars and a expect a bunch more to come up with electronics and a really big generator to equalize them. And several barrels of electrolyte.

Likely batteries removed from service at end of life and if you purchase them, you pay for disposal cost when they die next year.

Those batteries may be a good choice for a 3rd world country that owns one of the older US submarines.

I am definitely not advocating anyone actually buying them.

Why would you say, "likely batteries removed from service at end of life" ?

When the ad clearly states:

a) " ... New Stock from storage, never filled ..."
b) "... These batteries were stored inside for quite a few years, but were moved outside about eight years ago ..."

They have 250 Cells available !

Sounds like an off gridders dream of powering the entire home-site.

Because even batteries in "dry storage" age, and loose functionality. Generally dry shipped batteries have a 1, maybe 2 year life. These were likely kept in proper storage conditions - UNTIL the current vendor bought them from mil surplus and carted them off somewhere else. Outside storage is not approved for dry shipped batteries. And the vendor does not define
stored inside for quite a few years either. But if you think they are cheap enough, and you have a source of battery acid (check to see how much the needed gallons will cost to ship to you) They may work and you may be happy and prove me wrong.

Well I know a lot about them, I served in Silent Service. In fact it was my crew who maintained them and life support systems. Short answer is they are not made to be cycled. They are made a lot like Telecom batteries and use Lead Calcium alloy because they are used in Float Service. Subs have two battery systems; Propulsion and Life Support. Those are small very old and tired Life Support looking for a SUCKER. Only people I know of that use them are for extremely high current test to make Ball Lightning. Now you could use them to make a mighty fine Rail Gun if you need to take out say an Aircraft Carrier, armoured vehicles, buildings, or large aircraft. Put one in space and you can take out a city.

Creating Ball Lightning looks like a pretty expensive hobby. Uncle San doesn't mess around when it comes to submarine batteries. 25,000 Ah. that's some serious capacity.

They go up to 60 KAH. Navy is not stupid, no parallel batteries, just 300 in series. Not sure where 2.1 volts came from. They are Pb batteries and with that comes 2.2 vpc and Float 2 roughly @ 2.25 vpc.
