  1. Whether the battery is recoverable, completely life expired or in tip top health. It's then down to the edumacated operator to determine what they need to do next.
  2. That'll mean less money to spend on quality batteries.
  3. It'll measure things like battery internal resistance, ability to accept a charge, etc to see that in the first place it is healthy. I guess we have all seen a battery declared as faulty but showing 12v+ on it but under lid it drops off to say 7v or less. So although a battery using a Volt meter may show a reasonable reading it may not be in good health. After telling it what type of battery and what the battery SAE, CCA, Ah is it'll then give you a percentage score at the end. Plus a print out so the customer can easily see what the gadget is reporting back. Sealey do a cheaper version.
  4. Specific gravity reading of electrolyte is also useful if this can be obtained. If all else fails, buy a battery analyser. I use one like this with a printer but there are slightly cheaper ones. Basic print out shows state of health and state of charge.
  5. There are a wide range of enhanced charging systems available. Have a look at sterling power products A to B charger. Did you replace the whole bank or just the ones that were dropping off? Have a look through this too. It’s useful to understand alternators. Just because you have 175A you might not necessarily be getting a decent charge current. Depends on rotation speed.

  7. It’s your decision which way you go, either way keep it simple to install and simple to maintain. There are ways of keeping the vibration down. I have fitted to a wooden base and even straight to the steelwork with anti vibration mounts. The bigger noise generator to be honest is the click click click of the fuel pump. This should have come with a rubber coated p clip. This can also be fitted with an anti vibration mounting.
  8. Hi. What kind of charging system do you have on your boat and what is the output of the alternator?
  9. Don’t go pressure. Keep it separate. You need to be able to charge the system with antifreeze. By having the header tank you can easily do this. If for any reason the anti freeze that you may have in a pressure system somehow bleak back into your fresh water, glycol alcohol is highly toxic, you would become seriously ill if not worse. Keep the two separate.
  10. Yes you can. It can go in a cupboard, wardrobe so it's concealed. Some have had it on the wall so they can see the levels. Purely up to you where you put it as long as it's higher than the rads.
  11. Smart chargers will regulate the charge voltage depending on the battery type. Off shore there are all types of alternator enhancing products that will increase voltages and currents. Being kind to your batteries is key and getting the right battery bank installed for the purpose also. Semi traction came quite a demand from some of my customers with several years of problem free off shore power. Design it right from the start. Happy boating.
  12. I have fitted all of the above and my personal preference both as an installer and a user would be the Victron unit. Make sure you have the right charger for your batteries and it is set up correct. Different battery types can and should be charged at slightly different rates. The previous notes about charging at 15 volts quite rightly should only be done as an equalization charge but for standard lead acid batteries you should be in the 13.5 to 14.2 volts. As you start to get towards 14.4v onwards for prolonged charging, the battery will start to gas and you will smell sulphuric gas (Eggy farty smell). excessive charging will kill the battery prematurely so a balanced Battery/Charger % is preferred to smoothly charge the battery and not aggressively charge/boil them. Hope this helps?
  13. Hi, I Install and maintain Victron Invertor chargers. What model have you got and which red LED is lit? Firstly confirm that you have 230v coming into the vessel. The Inv/Charger should automatically go into charge ode when hooked up to the mains and depending on what model you have you may even have an ammeter that shows how much current is being taken to charge up the battery. Knowing which one you have and also which lights are illuminated would help further to offer you some sort of diagnosis. Some of the more complex models can be accessed by the laptop and settings, charge rates, etc. can be adjusted. Current limits can be adjusted and allsorts. Cheers.
