    Wow what a battery charger

    Posted by Mark on 22nd Sep 2023

    I have a 12 volt 500ah Trojan battery bank made up of four 6 volt batteries. It was about 8 years old and had served me well. It had been worked hard in an off grid environment. Recently the batteries quickly lost their ability to hold capacity. When put under a 200w load the voltage quickly dropped below 12 volts. I thought that was it for my £800 battery bank. I split the cells up into two 12v 250ah banks and left the OptiMate 7 Select on each one for 3 days on the 14.7v setting. I have now tested the batteries on very heavy loads and they are operating like normal. Amazing! 10 out of 10 for this charger.
