All of my batteries except that for the 8N and TO35 are "Maintenance Free", so there's no way to even check the electrolytes.
Both tractors mentioned aren't currently in use, pending maintenance and repairs.
That is one of the common connections for many of the failures we’ve investigated. Many standby units are now using maintenance free batteries because it’s getting difficult to find serviceable batteries.
The problem is the battery is the same, still uses up electrolyte, just no way to top up. Once plates are exposed, any arc from a bad cell connector or even a hot connection will ignite the hydrogen.
