The 2nd battery in the 4B is getting a wee bit tired. I've got a 25amp, 7 stage charger & have done a recon on it, but it's not holding charge too well. It's only function is powering a 20 yo, 40l Engel & will now barely supply overnight. What's the best specific house battery on the market? Do I go AGM? I've AC Delco Marine batteries in the boat & they seem OK. Also, someone mentioned that if the battery is being charged (has a solenoid) but not used shortens its life...True or False. Any advice appreciated
Cheers & a Merry Christmas & safe travels

i think with a 7 stage charger the last part of the 7 stages is more of a maintanance/float cycle...Correct me if im wrong.....that wont hurt ya battery..... :cheers:

Thats the way my Ctek M300 25Amp charger works, switches to a monitor roll and the gives a top up charge when the battery voltage goes below a preset level.
AGM is the way to go for a fridge, I use a 2 x 120AH FullRiver AGMs, Verypleased with them, my Arb 47l Fridge and led lighting will last 4-6 days depending on weather,

Sorry fellas, I should have been more specific. I meant whilst it was being charged in the vehicle.
I just sourced an Optima D43 yellow top for $245 delivered from ebay. I understand the Optima D34 is a hybrid style that has AGM and engine cranking capability, although its not recommended to be used as daily cranking battery.
Thanks Jim. I'll look into that!
Marine Start batteries are cheaper & supposedly give good service, AGM's are dearer but last a bit longer.
