That�s correct. I would like to add: 1. The charging method for this type of accumulators is constant voltage. The current limit is just for protection. 2. Take care not to exceed 2.45V (at 20 degrees Celsius) per cell. This will result in permanent lose of electrolyte. 3. When dealing with accumulators it�s always advisable to follow manufacturer�s rules. Best regards, Mircea > ----- Original Message ----- > From: Jeremy N. E.
