  • Plymouth Battery Centre Test

    **14th -16th Jan 2018**

    I've just been informed that Batt4 is poor and has a 10% capacity, it was subsequently charged and discharged and I was told it now has 25% capacity. It is being charged again and I should pick it up this Thursday 18th

    My attempt to remedy will be to charge at 15.9v until the battery is hand hot on a good day seeing the charge current at 6amps for say 6 hours. This may have to be done four or five times to get 120Ah into a battery. Rolls states that 125&Deg; F or 51°C is enough and if batteries reach that they need to be disconnected. This is around a temperate where it would be uncomfortable to leave the hand for a minute.
