Two possibilities.
One, nothing, that cell is history, or Two an explosion.That battery
is probably a write off. Bring it up to room temperature SLOWLY and attempt a recharge in a safe, preferably outdoor location. I have witnessed lead-acid battery explosions in automobiles. It is a memorable experience. RJ On 2/18/2015 7:18 PM, Charlie wrote:
When I was plowing yesterday, the I-5 was sluggish at first, and never really got up to the usual level of power. I also noticed a strange sulfuric eggy smell at times. When I put the charger on, it was unusually loud. So I checked all the batteries and I found that one of them had a single cell frozen solid! The other two were fine, as were the other five batteries. I was trying to be careful about not letting the batteries get discharged, to prevent them from freezing. In the fall I carefully checked every cell with a good quality temperature-compensated hydrometer and they all looked good. The charger and electronics are the simpler late model type, the tractor's a 1973 I-5. Does anybody know what happened here? Is the battery irreparably damaged? What happens when I charge the pack with one cell frozen? --Charlie _______________________________________________ Elec-trak mailing list Elec-trak cosmos phy tufts edu https://cosmos.phy.tufts.edu/mailman/listinfo/elec-trak |
