Before going away on trips, I now like to put the trickle charge on the Deep Cycle battery for around 4 days before we leave. Am I likely to cause any damage to the battery by overcharging it if that is possible to do?
Thanks for your responses.

Hi Des Lexic. If your battery charger is operating correctly then you will not overcharge the battery. When the charger senses that the battery is fully charged the charge current (amps) on your battery charger should read zero. Prior to putting it on charge check that your electrolyte levels on the battery cells are covering tthe cell plates. Add distilled water if necessary. Cheers.

I leave my 4 1/2 yo battery system, two 80a/h Deep Cycle batteries, wired in parallel permanently on the battery charger while not in the bush without problems.

My charger system utilises a 12 Volt, 10 Amp, Automatic Charger Control

which is wired directly to a 10 Amp manual battery charger, the controller will automatically turn the charge on and off to the battery as required by using a two stage charging algorithm which has setting for both "GEL" and "LEAD ACID" batteries.

On that note (and not trying to hi-jack the thread). Will the regulator from a solar panel (which I have on me trailer) do the same job,ie can I hook the Battery Charger straight into the regulator without burning the trailer.

I had a 4amp battery charger, but after buying it discovered it does not have a float capacity which annoyed me no end as i too thought what if i go to bed and it reaches max. charge on one of my smaller batteries (eg 33ah) and it pumps in 4amps all night - awful thought. So i then wired it to a 7amp solar charger that would stop the current flow into the battery when the battery was full and although i don't use the battery charger often now cause it is a dumb charger, it worked fine countless times to fully charge a number of batteries to a regular 12.65 - 12.70v (measured a few hours after charging).

G'day Mr Lexic
Bloke from battery place once told me that a deep cycle likes to be charged like that and in fact you can leave it charging for days without a problem. I have a 4 amp charger and often leave it for 2 or 3 days without a problem. Same bloke said the auto chargers are no good because they switch off when they reckon the battery's charged whereas the deep cycle needs heaps more.

Moose
that is the reason I use a Manual battery charger and run it through a 12 Volt, 10 Amp, Automatic Charger Control unit
http://www.projecta.com.au/products/index.php/productserial/20/command/viewproduct/categoryserial/10
the charge controller automatically adjusts the battery charger on and off as is required.

Try a charge n maintain battery charger from Projecta.
Mine charges at 1600ma until the batt is fully charged then goes into pulse mode and can be left on the batt indefinately.
Mine is installed in my van and remains hooked to 240 whenever the van is on power, which is all the time at home in storage.
I used to have a handle on life, but it broke.

Cheers Dodg.

On subject of batteries and storage issues - this mob have an IPO out at the moment in Australia, haven't got the prospectus yet but its in the mail. i notice they have put "non-flow" batteries in a wheelchair - would love to get my hand on one, even if i don't know the specs.

maybe if i become a shareholder they'll give me a good deal.

Yes signman, that is still the go but the first part of the trip is beimg organised by someone else in a convoy of 6 vehicles.
We have had to refuse other requests from fellow club members to join us on this trip so I can't very well invite you to join us for a section of it. Can you try a post and see if anyone else is doing the trip around the same time.
Sorry and good luck
Des
