Yes, we can justify it with numbers and spreadsheets. You know the saying, if you can not dazzle them with brilliance, you baffle them with ,,,,,,,,,,,,

The 95w is 21" wide x 41" long and the 160w is 26" x 58". If they mounted the 95 like the 160 the square aluminum tubes glued to the roof are probably too short. Something would need to be modified.

I was going to add the 160 watt and still keep my 95 watt, I believe they mount the newer, bigger ones in the rear, my present one is in front of the a/c.

Where is the Jack in relation to the 95w?

As batteries age the impedance increases, this resist the charging process. This process is increased by charge and discharge cycles. This internal resistance effects the batteries ability to provide current to the load and to receive an effective charge. Placing batteries of different ages can cause the newer battery(less resistance) to accept(hog) the charging current, and the load current. If the difference is large enough it can overwork the newer battery and shorten it's life span.

A good practice is to match manufactor and type of battery as much as possible. A year old battery matched with a new battery should not be an issue unless it has been subject to a large amount of cycling, or repeated discharging below 50% of its capacity.

Thanks Barry, that is what I was thinking. Have to check the manufacturer, it maybe Lifeline.

Alan,

I assume you mean a sealed lead acid battery, every lead acid battery generated hydrogen gas as it is charged. The higher charging current the more H gas produced. As long as the battery is sealed the gas is contained. The seals around the post are fragile and can be damaged when tightening the connections. When tightening the connections use a backup wrench to minimize the twisting effect.

I prefer my batteries where I can add water when necessary.

Unless your camper is tightly sealed the hydrogen gas that should happen to escape from a battery will dissipate in the use of doors or windows.

The trailer manufacture is erring on the safe side as the amount of water in the battery would be hard pressed to create an explosive atmosphere. Hydrogen generation is more problematic in large banks of batteries which have the ability to create large amounts of hydrogen.

Just wanted to vote a "thumbs up" on this opinion. I worked in medical - rechargeable battery systems, and we always cycled new multiple battery power systems on Maccor equipment to insure the "as shipped" battery impedances matched. Every AED (Automated External Defibrillator) is powered by matched impedance batteries.
