Duel Battery maintance

Wato35

ANY battery will last longer if it is kept in a fully charged state, it is not advisable to let any battery run down to its considered flat state of charge and not take action to return it to a fully charged condition.

Any battery that is left in a state of discharge will very quickly become totally unusable.

As Athol wrote you shouldn't run them down to far, preferably not below 60% for deep cycles or there abouts, and they should be fully charged ASAP after being discharged. They should be stored in a fully charged condition and have a regular maintenance charge whilst stored.

Hi wato35,

As already stated keeping them charged is ideal, and with the price of the smart chargers being a reasonable price it is easy and cheaper than letting your batteries die.

The statement that :

"ANY battery will last longer if it is kept in a fully charged state"

is probably true for Lead Acid/ AGM batteries etc but not true for Lithium batteries for which it is generally recommended that they be stored at less than fully charged.

I always plug the van into the power when at home and let the Ctek look after the Delkor 80ah battery. 7 years old and just changed it for a new one.
80ah is all we need for the lights as we don't run much in the way of electrical stuff when away.
Compare that to the constant purchase of new batteries for the Cooks Camry which I'm afraid to say I neglected battery wise.
I could have saved a few bob by buying a Ctek years ago but didn't for some reason.
Keep it charged and it'll last much longer.

With the amount of different types of deep cycle batteries available it may help to mention what type your specifically looking at.

My two 110amph batteries in my Complete Campsite Exodus are 7 years old and still hold full charge. The camper is stored under an awning and has light to the 135watt solar panel so is constantly trickle charged through the MPPT charger and then the DC/DC charger. The Ctek 25amp charger does the job before each trip and when in caravan parks but usually only a couple of times a year as we generally bush camp.
