Hi 

I acquired 24 X Hoppecke 600 Ah 2v batteries commissioned September 2008....was used with SMA SB 4000 Tl and SI 5048.

 

24 x Hoppecke 910 Ah 2v batteries commissioned June 2015 ...was used with SMA SB 5000 Tl and a SI 5048 

These batteries were fully operational when decommisioned, stored for a year and when contractor was commissioned to reinstall he told client he does not install crap ! ( Probably installed one of those blue things 😜)...that is how I got them ....( 48 batteries X 40 kg x7.00 / kg 

Now I am from the era when things worked and when they did not you made a plan !!!

Hoppecke batteries are sapposed to have a life span of between 15 and twenty years ?

Any advice on how to proceed to recondition or get some life out of them...am doing research before talking the project...there are a few old bellies in this forum I have been stalking here since "king" Arthur's days with his MLT bi-directonal inverter 😜

thanks ,cheers Roland

I think you need to start by contacting your municipality and apply for a permit to store so much lead on one property 😜

Thats quite a bit of power, you are going to enjoy load-shedding.

Go to Midas and purchase a battery Hydrometer.

Check the liquid level on each battery and fill up with distilled water. If the cell is very low you will have to add acid as well. You can also purchase ready made electrolyte from Battery center

Test each cell using the hydrometer.  The hydrometer comes with a card to show what the charge level is.

If the cells are flat you must charge them up and test them again. Depending on the cell info you will have to charge them between 2v and 2,3v. (if you do not have a 2v power supply connect 6 of them in series and charge them up this is not ideal because the cells will not balance if there is a faulty cell)

Leave them for one week and test the cells again. They should not loose a lot of power if they do it means they have a problem internally.

If you connect these up after you have found enough cells that work you will have a mean battery, Install this battery in a well ventilated area because they will gas.

Check the electrolyte every 2 weeks and top up if necessary

Is this possible to do on Gel Batteries?
