I was away from home for six months this year and stupidly left my two Pismos turned off and disconnected from mains power. Both batteries went flat, and I now find that my two previously working batteries will not charge fully: the older one will only charge about 25% (two lights), and a newish one that gave me about 4 hrs when I left will not not take a charge at all, beyond one blinking light. To be clear, the latter battery is recognized, and there is an initial charge taken (so the battery monitor says and so the blinking light indicates) for a couple of minutes, and then the charging stops. Eventually, however, if I leave the battery inserted, the PB no longer sees the battery, until it is removed and reinserted.
On my old Wallstreet, it was often possible to revive a disused battery by repeatedly reinserting the battery so that an initial "burst" charge was taken for 15 seconds or some such. After maybe 50 tries, the charge would or could eventually "take," and all would be well.
I've been trying this with the Pismo batteries. The old battery that charges to about 25% may be beyond redemption, as I have seen that behaviour before (I'm going to try cycling it next, so see if that improves matters), but I am hoping that the other newer and better one in particular can be rehabilitated. So far, however, the insertion/ reinsertion until charging stops method has not worked.
Has anyone managed to revive a Pismo battery by insertion/ reinsertion, along well-worn Wallstreet lines, or am I flogging a dead horse?
