Subject: do not ROB your BATTERY BANK
(Posted on Feb 28, 2013 at 07:42AM by Colin Jackson)

when thinking of the battery bank aboard a cruising yacht, I like to think of a bank account (seems a very convenient analogy) 

 

when your battery bank is FULLY CHARGED, you are comfortable & can use equipment at will ~ not unlike the great feeling of that full bank account

 

as you make withdrawals from this bank, you need to start considering how you will make deposits back ~ that same uncomfortable feeling associated with a dropping bank account comes to mind (see how relative this analogy is?)

 

* the alternator on the engine is one way to bring the batteries back up

* the shore power charger is another way

* some boats use solar & wind generators

 

unlike my cel phone, which seems to still work when the gauge says 2%, the battery bank on the boat shouldn't go below 50%

 

conversely, it is very hard to get right to 100%, especially when out at anchor or motoring

 

every boat is a little different, but you might come up with a zone between 50 - 90% - meaning you make sure you start recharging as you approach 50% & you keep that charging going until you reach 90% (knowing below 50% will hurt most batteries and above 90% might just be too hard unless you are alongside with great shore power)

 

BUT HOW DO YOU KNOW?

 

some people talk about measuring voltage, but that's going to throw you bad information if you've just been charging or drawing (making deposits or withdrawals) - so we're working to add BATTERY MONITORS to our fleet - these 'battery fuel gauges' are the only sure fire way to know where in fact the bank is 


 

don't ROB the BANK ~ related MYSTERIES & MISCONCEPTIONS

 

~ some people over the years think that when you plug the boat in, DC appliances magically change over to AC appliances because the boat is plugged in ~  this is not the case ~ but you may be making withdrawals & deposits at the same rate and holding your bank balance 'even'

~ be aware of multiple chargers when they exist and make sure you have engaged all charging devices you need

~ also be aware that a big invertor/charger may take everything the dock can throw at it - so not the best time to also have hot water tanks & other high load items pulling too

 

we're 'generalists' in this arena, if you want more specifics & an ability to dive deeper into this, check out the informative website of PACIFIC YACHT SYSTEMS - presenting at our YACHT EXPO SEMINARS

simply put - we collect experts for various YACHT and CRUISING topics and get them together to kick our BOATING TIPS & TRICKS philosophy to the next level

whether you are just starting out or contemplating crossing an ocean - one of these (or all of them) will amaze you, inform you or get you that AHA moment over something that puzzles you when afloat



at COOPER BOATING, we have to be generalists in order to keep a whole bunch of different boats in top form - but we have a collective team of strategic partners that are the true specialists and yacht experts - from building entire boats to BC boat sales experts who know how to scour the planet to get you the best deal

we have people specialize in rigging,  engines or boat wiring as well

these sessions represent a building wave in shoreside boat clinics - and an opportunity to test drive for some of our classes

everyone wants to share their expertise and make those all important face to face connections to truly make you READY for FUN on the WATER

what does it cost??  we cover all the expenditures but want to do something great at the same time - so please bring something for the FOOD BANK so we can give something back -  from those fortunate enough to enjoy time afloat to those who need a helping hand at this time

in a recent ALBERTA session one participant said "it's like drinking from a fire hose" -- we're adjusting the format to keep these passionate experts to a manageable pace!
