need battery diagram

[Newell Attack]

batyteries completely dead and have since replaced the batteries and they are still going dead ... had 4 batteeries now five need a diagram on how to hook up batteries .. for the coach ... saw it here before but could not find it .....all batteries good load tested good charge good ..... batteries dead overnite .. have double checked to make sure nothing on ,, after recharging twice now .. and have read and read .. wont to start with making sure my batteries are hooked up together first then step to next phase all terminals cleaned .. when hooked up

Assuming you are still using 12 volt batteries which is what Newell uses, the negative cable is hooked to the negative terminal on battery 1, a jumper cable goes from the negative terminal on battery 1 to the negative terminal on battery 2, another jumper cable goes from the positive terminal on battery 1 to the positive terminal on battery 2. If only two batteries are in parallel, the positive cable then is connected to the positive terminal on battery two.

In short all the negative leads are tied together, all the positive leads are tied together with the negative cable tied to the negative terminal of the battery at one end of the battery bank the the positive cable tied to the positive terminal of the battery at the furthest away.

My coach uses two batteries in the chassis or starting circuit and two in the coach or house circuit. These batteries are isolated from each other unless the battery merge switch on the dash is activated.

If your batteries are going deal overnight, either one of the batteries is reversed in polarity or you have an extremely large draw on the batteries such as a short.

Give us a little more information on your hookup and we will try to help out.

Remember NEVER use series wiring unless you are dealing with 6 volt batteries OR in the case (a manufacturer of conversion bus shells) where 24 volts is used. I have never seen a Newell that was using 24 volts.

- When you play-around with 'Batteries ;'
- To get the max out of your 'Batteries' in time and power 'Batteries' should always be
charge individually before connecting them together.

- My Problem : I can't recall if it was in series or parallel or both. I'll try to locate documents
about the problems of connecting batteries. It's not something that many persons will
agree because they never tried-it.

- Case : if you place a new battery with older batteries, it goes something like this :
- - Older batteries have already a charge. The new battery doesn't.
- - the charging system will always try to charge because the New Battery will demand
and the Older Battery(ies) will boil and both will loose their capacities earlier than expected.

- If batteries are almost 50/50 for sure there isn't a problem but if there's a substantial
difference in voltage between them, in due course there will be a problem.

- Perhaps someone can add and fill the blanks or . . .

It is always best to install fully charged batteries into a battery bank regardless of whether they will be wired in parallel or series. If there is any question as to the level of charge on a battery being put into a battery bank, it should be fully charged first. Make sure that the charger is set for the correct voltage before charging.

All batteries wired together should match as far as type, voltage and amperage. Don't mix and match.

As KC says, don't mix old and new batteries. There is one caveat I will add. While it is best to change all batteries at the same time, if you don't merge the house and chassis battery banks together other than on an emergency basis, changing batteries on one system or the other (house vs chassis) can be done without changing the batteries on the other system out.

Additional information:

Parallel vs Series:

Batteries wired in Parallel: voltage remains the same, amperage is the sum of the amperage of each of the batteries.

Batteries wired in Series: voltage is additive, amperage remains the same.

Newell uses 12-volt batteries wired in parallel so regardless of how many batteries you have, they will provide a nominal 12-volts. Adding additional batteries increases the amperage available for use by the systems on board. Many RVer's (primarily non-Newell owners) like to change out 12-volt batteries for 6-volt golf cart batteries. To get back to the 12-volts that the systems in the coach need each pair of 6-volt batteries would have to be wired in series then each PAIR of 6-volt batteries would be wired in parallel to other pairs of 6-volt batteries as shown in the above diagram above as Series/Parallel. So far, I have not seen a Newell equipped with 6-volt batteries.

Since the battery charger does not charge the chassis batteries unless the merge switch is in the merge position(s), the chassis batteries should match and be changed out at the same time as the house batteries OR an alternate charging method used for the chassis batteries when the coach is not been driven for extended periods. The Echo charger or the Trik-L-Start will both work for this purpose.

Newell recommends a PulseTech be added to existing battery systems as well to extend the life of the batteries.

I find electricity an interesting subject so everyone is welcome to expand on this topic.
