    230 Amp lifeP04 battery

    I found this battery to be very well built and easy to install. The size is nice and compact. Connections are very easy and the online instructions are great. We were away over the New Year’s weekend in Glenmaggie, I had my Bushman 52L fridge running off it for four nights without the vehicle being started and it had only dropped down to 76%. A drive to Licola and back the next day brought it back up to 100%.Very happy with this purchase.
