That's 2.4v/cell. That's a good voltage to insure that you reach full charge in a reasonable time, and very low water usage. You need to hold them at this voltage until the current drops below 2%-4% of your battery's capacity at the 20-hour rate. I think they are rated 150 amphours, so this means 3-6 amps. > Equalize Charge - 166V and hold for 45minutes That's 2.6v/cell, which is quite high. The real point is to limit the current to 2%-4%, and hold it there until the voltage stops rising. New, it may actually reach 2.6v/cell. As the batteries age, the final voltage at this current will get lower and lower. You don't want to charge at high currents *and* more than 2.4v/cell, or you will get serious gassing and high water usage. Also remember that these voltage must be temperature compensated. The hotter the batteries, the lower the allowable voltages. -- Lee A. Hart Ring the bells that still can ring 814 8th Ave. N.
