Is three years to short a time for batteries to last?

Our 2014 5.0 has dead batteries which is interesting because we just had it checked out for the season by a nearby R.V. shop and they said everything checked out fine. I'm going out to have a look and see if I can see why in an hour or so and would like ideas what to look for. Could they just be dead? We have the Interstates it came with, would Tojan be a better choice? Thanks for any help.

So much depends on use. If batteries are drained deeply - say down to 50% level frequently, 3 years might be a reasonable lifespan. I baby our batteries; never discharge them deeply and use a BatteryMinder charger on them in storage and our 6 year old Interstates still perform like new. They are expensive - make sure that they are really dead before you replace them.

I would first look for dirty, loose or corroded connections on the batteries. That seems to be the most frequent problem. Clean the tops of the batteries and check the water levels also.

My group 29 12 volt had one bad cell after 2 1/4 years. I switched to Us Battery after finding that Trojan moved production to Mexico and Saudi Arabia. I took the opportunity to switch to two 6 volts. Test the specific gravity to check the battery health.

We have never taken the batteries down below 90% and then not more than once or twice. We have about 240 watts of solar panel on the roof and always leave her plugged in when it is cloudy out and let the solar panels do the work when it's sunny.

Al - in that case, unless you just got a bad one, it could well just be bad connections. I'd clean everything, charge them, then if you have a hydrometer check each cell to make sure that they are all about showing the same charge. If you don't have a hydrometer, check your voltage after letting it sit overnight after the charge.

Also, after the full charge be sure to turn the battery disconnect switch to the OFF position. That will make sure that there is no drain on them from anything.

I you don't have a hydrometer, Al, I have two of them. You need to take a walk anyway.

How many beers do you charge for the hydrometer rental?

I agree but I take it one step further. I remove the battery terminals to completely isolate it from the trailer. Charge and test. That way I'm absolutely sure that it's not something else like a poor connection etc. downstream.
