All,
Having just taken delivery of a new 4310, I have followed the threads on battery problems with great interest. This weekend I paid a visit to the dealer to discuss the problem. The head mechanic there was very helpful. He said, yes there was a problem with battery leakage but Deere corrected the problem in late 2002. He then did some research on the dealer-only (DTAC) service and showed me a copy of the result. The Situation in DTAC is described as "The oil cooler corrodes and leaks on hydrostatic CUTs due to battery electrolyte gas drawn through the aluminum oil cooler by the engine fan. The DTAC Solution (#57831) reported as follows. "Install a new oil cooler and battery. The redesigned battery (LVA11726) incorporates six threaded vent caps instead of the two manifold caps. The electrolyte condenses in the vent cap and drains into the battery." I checked my machine and it has the "new" LVA11726 battery. Hopefully I won't have the problem and the mechanic claims that even a sealed battery like the Optima or a gel still has a vent that can cause problems while the new battery from Deere has eliminated it. He claims he is no longer seeing the problem now that the new batteries are installed from the factory. However, it would be helpful to know if anyone is still having battery corrosion problems even with the new factory LVA11726s?
