I have two dead sets of L110 high capacity batteries. I opened carefully both battery plastic cases with a very sharp knife and I'm sure that I will be able to close and seal them again. I found that each set has 6 Panasonic Li-ion cells: each two cells are arranged in parallel and the three pairs are arranged in series. I measured the voltage of each pair without cutting any of the metallic welded bars that "wires" the cells. In the first battery set I found 3.45 volts in the 1st and 3rd. pair and 0.54 volts in the central pair. I presume that the central pair has one or booth cells dead and that the other 4 cells are OK. In the second battery set I got around 0.5 volts in each of the three pair of cells. But I think that it is difficult that all the 6 cells are dead. All the measurements were done after some hours of charging. The first set reached 54% in the power properties of the L-110. I did not test how long the charge lasts when in use. The second set reached 3% and the L-110 does not work with it. Now I'm in doubt on how to proceed. Is there any clever way to identify what are the good cells, if any, without cutting all the cells "wiring" and test each cell? Is it possible to test each cell? What is needed to do it? What else can be done in order to have one good set from the two dead sets? Maybe some of you have experienced some trial in refurbishing L-110 batteries. The reason that I want to do it is that it is almost impossible to get new L-110 batteries in Brazil, where I live. If I buy it from other country (and it is difficult to find who ships abroad by paying with International credit cards), I'll be charged by the customs in additional 200% of the total price (battery, shipment and insurance). It is a lot of money. Thank for any help.
