hi, I need to replace my leisure batteries. Id read that it is better to have both the same capavity, age and type. Any recommendations based on actual good experience in terms of type. I have space for two batteries under each of the front seats for batteries no more than 38cm long. In terms of capacity i'd probably get away with 160AHr total. I dont have microwave of sat dish etc, just a TV, DVD player and the usual pumps and fans. I will be repkacing all bulbs to LED. Prices also welcomed. Thanks
