Moisture on batteries

[YodaDad]

Batteries charge fine, S/G is very good in all cells, fluid level in cells is appropriate. 48volt system 6, 8volt batteries. When I check the voltage on my batteries they are always wet any idea why? Thanks, JAL

If you could, please check the total battery voltage when the charger is almost complete and the scale is under 5 amps. We may have an overcharging condition causing the sweating.

You can call my office with the results and I will call you back for discussion.
