Portable Battery

Hi Jag, doesnt sound like you need a second battery if you get 2 hrs of recharge in a day. The fridge will not flatten your battery over night. If you are worried about it doing that though, buy one of these cheap 3 in 1 battery packs and use it to power the fridge once stopped for the day.
Good to take in the tent, pump up the mattress, use the light at nite and will even provide a ciggy lite lite!

Hi Jag I don't know much about batterys but I'm in the market for a second battery as well so I went to the battery shop the other day and this is what I was told. A true deep cycle battery wont charge anymore then about 80% on 4x4 they need around 15.2 v a 4x4 is around 14.5 and carry a bleep warranty around 6 months. He said because I will be driving around a couple of hours a day I should be looking at a marine battery they have heavy plates and carry a good warranty and have a good cca.The one he showed me was 80ah with 2 years warranty for $145.
I hope that's been some help

Hi,
About deep cycle batteries....
1stly a deep cycle battery shouldnt be flattened, you will do damage if dropped below 11.6 volts,2nd dont beleive battery sellers they will try to sell you the most expensive battery available.
3rd a deep cycle battery will not accept a fast charge, because of the way the internal structure is, an if flattened too much, may take many days to revive on a trickle charger with no loads applied.
The best bet is an ordinary cranking battery, sealed if being transported in the vehicle, as they will accept a rapid charge from your alternator, and they are cheaper.
