Hi Ron, if it’s split at the bottom, it is probably pulling air in as it cools and as it expands through warming while charging, it’s forcing electrolyte out.
The electrolyte is usually a gel form but it still liquifies.
Next, what do you call high current charging, because as your battery is a 100 A/H your battery is rated at 20 amp maximum for charging, so anything over 20 amps is not recommended.
