Check the wires with a voltmeter if in doubt about which is positive and which is negative. The trick it to have the alligator clips on the output side with the positive and negative wires clearly identified. Mine fortunately came with a two pin connector wired to a multiconnector, so I simply cut the wires at the multi connector and put the red insulated clip on the positive side and the black clip on the negative side. The charger must have a 20v output position on the selector since these are 19.2v batteries. Yours may be different depending on where you live, but there are cheap universal laptop chargers (made for lithium batteries) readily available. I live in Mexico and bought my universal laptop battery charger on for about $10 dollars. With the second battery, I took pictures so you can see the process. I soldered a couple of wires, reassembled the battery without the circuit board and charged it with the laptop battery charger. I simply removed the circuit board, verified that the batteries were connected in series and bought a universal laptop charger with multiple voltage settings. The thought occurred to me that the batteries might be good and could be charged with another charger. Nothing was obviously the problem as far as the circuit board was concerned. Out of curiosity I took one apart to see if I could figure out the problem. Worse, the company who sold them to me was no longer registered on eBay. The charger would show the fully charged green indicator light even though it had no charge. The joy ended after only one or two recharges, as the batteries would no longer charge.
