Just wondering if anyone figured out the charging regime, literature says initial charge should be 14.7 Volts at about 30 - 50amps but I thought the battery resistance would set the amps ccording to the voltage but the literature keeps referring to setting the amps??? I have a C-tek which will set at 14.7 volts on "Snowflake" setting but it only pumps out 7amps max....anyway anyone figured it all out?
My guess is that it will just take longer to charge.
The voltage is the important bit.

What size C-tek are you using?
Crunchy, I thought you were feeding your battery drugs, I looked it up and found there is such a thing. I do like the idea that apparently you can completely discharge the battery without shortening it's life. What was the reason you went down this path.
PS I checked a few forums and they all seem to say that the batteries will charge but take a lot longer, 36 amp seems to be the recommended range though.
I think they probably mean depending on the battery size the initial charging current from flat @ 14.7 Volts would be 30A - 50A or to limit the the charge rate to 30A-50A. (Typical battery recommended max rate C/3)
That's IF your charger has the grunt.
A 7A charger from flat will either cut out, protest a short circuit, cycle on & off or continue plugging away until the charge comes up just like a normal battery.

We put a teaspoon of cement in each battery to save on battery acid so we can make more money.
That must be right but they talk about set current and set voltage, must assume a charger with settable amps?? - see below.Originally Posted by 552Evo

Mate I'm an early adopter of technology (Nah not really, the battery sales man said "try this"), no reveiws in marine applications from what I can see but the ability to go below 50% DOD without crapping the battery is appealing and very high number of life cycles means cost in use should be very low....time will tell I guess. I guess the amps discussion refers if batteries are compeltely discharged.
Yeh I think your right, given the battery is new I will just throw the c-teck on snowflake (Which is 14.7 volts) which is the reccomended initial charge voltage and move to "Auto"mode after that....to maintain the 3 year warrantee you need to charge correctly and the high inittal volatge is to turn the lead back into crystals.

G’day Crunchy,
I’m pretty confident your Ctek will do with the job. As I mentioned it will just take longer at lower current/Amps. It’s probably got 7 or 8 charging steps to complete all the appropriate stages of battery recharge, rejuvenation and what not.
Just make sure you set the Ctek in the appropriate charge “mode” and from what I’ve searched for your lead crystal battery the “AGM” mode is the appropriate charge mode for a lead crystal battery.
In all the charge modes the main influence on how the charge is received by the battery is the voltage.
The current is either restricted or flat out (within the chargers capabilities of course).

Only issue you may face is with a very flat battery the C-tek may throw it's hands in the air and tell you to bugger off. I have seen this with smart chargers before and keep an old style Arlec charger specifically for this reason. If necessary I throw the Arlec on for a short period until the battery has enough voltage that the smart charger is happy to charge it
Yes agree with scottar 100%
I’ve got a projecta charger that has power supply mode. If the battery is dead flat and the charger won’t start then charge it on power supply mode for 30 mins is usually enough and brings the battery base battery voltage up enough to allow the charge mode to grab on and do it’s thing.

The maker of these batteries (Betta batteries) have developed their own chargers with their recommended protocol but can't find where to buy in Australia.... or o/s for that matter
Crunchy, take it back to the salesman and get him to charge it or I have a 10 amp AGM charger your welcome to borrow.
Did a quick search is this what you are after ?

Honestly I don't think you need it. All you want to do is to keep it charged while not on the water ?? Your battery won't be dead flat every time you charge it.
Big output style chargers like that are usually for battery banks, like in a forklift. I reckon if your ctek has the AGM mode then that will be fine.
It's your battery and your dollars invested, so it's your choice.
Cheers

You just reminded me I got a forklift charger at work....I'll stick the bugger on that of it ever goes flat!
Not sure about yours but our forklift charger puts out about 48 volts. You might let the magic smoke out - once you've done that she's cactus.
It will teach it a lesson for being difficult though
