Storing Batteries

Truckster,
I use a deep cycle for an elec motor, it stays on a trickle charger all year, I also take it camping to run the fridge off. It's 2 years old and showing no signs of killing over yet.

Batteries will store ok for a couple of months if they are fully charged. They will "self discharge" (starters more than deep cycles), but if you recharge them every couple of months then they'll be ok.

Also may be worth looking into a megapulse (claims to reduce sulphation which is often the cause of premature battery failure) especially if you can't always recharge a battery immediately after a discharge.

There is also the option of the Optima spiral batteries which can be used for both deep cycle and winching or starting, but they are only rated at 55 Ah so they aren't the greatest deep cycle (and they are over $400).

Truckster. I use a 12volt, wet cell, automotive battery for camping purposes and do the following. I recharge it after each camping trip and the first day of each month. I store it and charge it on a thick block of wood and it lasts for years. This is the advice given to me by the battery company and it has stood me well. Hope this helps.
