Batteries Submerged

[Kero]

Hey Robendog, it's up to you how you feel about the batteries (maybe give them a trial outing before your trip if it will help ease your mind).
For new batteries, the SeaMaster Gold are great bang for your buck, and they have a built in hydrometer sightglass. They perform very well withoit emptying your wallet.

THIS IS WHY

as quoted by Robendog
Heading up to 1770 for fishing hol next week and dont want it all to shit itself while we are away.

The answer is all about the question

A holiday like this costs a lot of time and money [approx 400k drive each way for Robendog, getting boat serviced , time off & accommodation] just to get there and then if you’re lucky u might get some good weather and be 70ks out to sea so why chance being out in a foreign place with the possibility of dead batteries which then means no radio and trying to get in touch with someone to then somehow try to get towed back and losing a day on the water only then to top it all off by paying up to twice as much for a new one as u are in a small town
Batteries are consumables like Impellors, fuel filters, spark plugs, tires & wheel bearings on your boat you don’t wait till it breaks up, blocks up, breaks down, and blows out till you change it do you ?
The trip in question is not a river run where u may chance it
You say batteries don’t just fail well I am a jinks its happened to me 2 times in a work cars and once was after getting it load tested 2 days before, and then a few weeks ago I helped a person get his car of the ramp after he reversed his car down stopped it only for it not to start [there is more times but I wont go on]
As I have been on quite a few remote trips like north west, stanage bay, fraser island you soon learn the importance of upkeep
I chose to change my batteries at 2.5-3yr mark at aprox $150 if you decide to keep yours 6 yrs that is your decision but for the extra $25 a year it costs me this is small price for insurance for me as even if u have a 500k boat without working batteries u might as well be sitting on a couple of 44 gallon drums if u cannot use it
Robendog may get away with using them but is it worth the price
Your maintenance can save u a lot of heartache and maybe your life

Ps: You said in your first post it looked like a sealed battery your next one said test it with a hydrometer you forgot to tell him what size hammer & chisel he should try to open it with

Well thats your choice, the money you spend/waste on replacing good batteries buys me fuel and booze. I am a mechanic by trade and can tell you that a battery average life is 4-5years, its your choice whether you choose to believe that or not. As for your battery "just dying" you clearly had/have an electrical fault which is putting a drain on your battery or your alt is not correctly charging it.

As per your last comment i have not seen his battery, if its a sealed unit then you are correct that you cannot test with a hydrometer but the battery shoud have a check window in it, as for your load test that only tests the CCA not the batteries ability to hold charge.
