Re: House Batteries 6volt deep cycle
We had 4 Costco Interstate 6 volt prior to installing a residential refrigerator, at that time we added 2 more (6 total replaced all at the same time) still CostCo Interstate. Over the last 20 years we have had 4 different units with various batteries and are very happy with the performance of these Interstate batteries. As a practical matter I do lean toward one of the prior postings, in that, all batteries are manufactured by 2 or 3 makers and as such in many ways there is little difference. Proper use age and care play a major role in both battery life and efficiency.660Views0likes0CommentsRe: Coach Batteries
Rick and Vikki, My understanding would be that you have a total of 4 6 volt batteries 2 each connected in series (for 12 volts) and the two 12 volt groups connected in parallel giving the total 12 volt amperage to the coach. Assuming the batteries are all the same age and one has failed due to age, sulfation, ect., conventional wisdom would have you replace them all. That said, and there is some controversy here, but if you are confident in the condition of the other batteries, you can,technically replace just two--the known bad one and its 6 volt mate in that 12 volt series. Many lab and field test have demonstrated over the years that the charging system can compensate for differences in batteries wired in parallel (such as batteries of different amp ratings and to some extent ages) but not when wired in series. I'm sure I may get some push back on this, and rightly so, because as a practical matter batteries are generally replaced all at one time in a given bank. However, that may not be always necessary if they were not purchased/or been in use, the same period of time.But clearly only in parallel wiring thus the minimum of 2. Kind regards.333Views0likes0CommentsRe: tank monitor
Unfortunately, as a previous post indicated, there is little or no adjustment available on any of these systems. Our experience through several different units over the years is that they are seldom very accurate. That said, most offer at least some guidance once you become familiar with how the readings relate to your particular unit and its characteristics.181Views0likes0Comments
