Marine battery advice

[sharkboi]

Just looking into buying a deep cycle marine battery to power my fishfinder, lights etc and was wondering if you can use a car charger to charge the deep cycle battery

Cheers!

You should always use a multi-stage charger for a deep cycle battery to extend it's life - at least 3 stage with the final stage being a trickle or maintenance mode.

Basically you leave the charger connected to the battery whenever it is not in use.

You can get a MXs 5 cheap on ebay too. I got mine through these guys

You have to use one for each battery type because they have different optimum charging voltages.

The mx5 is way too small for recharging deep cycle batteries for leccies. It would take 20 hours to recharge a 100 a/h battery so you could only use your boat evey second day.

Something like this projecta on ebay ( ITem no 110809008670 } nis what I would recommend. Aussie firm excellent warranty. If it fails in first 2 years you just ring projecta and they arrange for you to pick up a replacement at nearest Repco store.

I ended up buying the 12v remco deep cycle battery from whitworths however i am wondering can i charge it with a 12V car charger? (from auto barn/supercheap)?

You should use a multi stage smart charger on all deep cycle batteries.

You can use a normal charger but it will dramatically shorten the life of the battery.

Thanks aussie

Would this charger do the job?

That charger will do the job but its only small.

If you only have a small battery though it will be perfect and c-tek is quite good gear

[sharkboi]

Yeah i have this - https://www.whitworths.com.au/main_itemdetail.asp?cat=123&item=4145&intAbsolutePage=1

Which is pretty small so i guess the charger would be fine

i got a 55amp hr charger projecta brand which is narva from queensland diesel spares for $90 it is supa

[aussie123]

That will be fine sharky.

You will be looking at around 5 hours for a full charge
