I typically hate BCF as they are overpriced for almost everything.

Credit where due though, this 730 cranking amp battery is well priced at $183.

NOTE: To get this price you need to be a BCF member. Membership is totally free.

SuperCheap Auto want $228 for the identical battery (and that is on special down from $269).
SuperCheap will price match if you don't have a BCF near you.

Repco sell the same battery, but rebadged Repco - they want $240 and it is excluded from all % off offers including today's 30% off for motoring club members.

Be safe on the water this summer - pack a spare battery in the boat, particularly if you are thinking of going offshore or staying out overnight.

There are probably better marine batteries out there (Sea Master Gold are pretty damn good) - but at this price point you'll struggle to beat this and it comes with a 2 year warranty.

    If you can afford a boat that needs a starter motor, you have come to the wrong website. :-)
    (or is this a standard thing on outboards now?)

      Most outboards over about 40 horse power are electric start not pull start….

      If your boat isn't a small runabout, chances are you'll need a battery to start the engine - perhaps not something as big as this which is really aimed at larger boats (but you can use a large battery in a small boat - not vice versa).

      I have a 50hp motor and a modest boat - this battery is overkill for it, but the high capacity is useful for overnight trips powering lights and other accessories. Also at this price, the incremental cost for a very large increase in capacity is very small.

      Hell even if you have a tinny with a pull start motor, this sort of thing can be damn handy when you want to go prawning and doing stuff at night. At 180 RC (Reserve capacity) it will power a lot of stuff for a long time…

    • Pretty much all non-portable outboards are electric start ie. have a starter motor.

      BTW, good price for a deep cycle battery of that size

    • oars are cheaper ;)

      • +5

        oar are they?

        • Sounds like a load of rowlocks to me.

  • Is there any reason I couldn't use this for camping/boat trailer purposes?? (I have a kayak trailer that I want to put a water pump onto with tank so that I can hose it all down after salt water). Plan being to also use the trailer for camping purposes. I have a large metal storage box on the trailer and plan to mount a solar panel to top up the charge whilst park (ie not ever connected to car electrics).

      Being deep cycle, it should be fine. Some things to consider:

      1. Size your solar panel so that it doesn't take ages to recharge.
      2. How hot the metal box will get. Excessive heat will shorten the battery life.
      3. Never discharge the battery more than 75% (ideally not less than 50%)

  • Hmm I need a new one :)

    Would this be better than a Neuton Power DC27 that is only $176 new?

    • +1

      Depends what you want it for.

      The DC27 is a DEEP CYCLE battery. It is designed for systems where you have 1 battery starting the motor (not a deep cycle) and one battery powering the accessories (the deep cycle). It is primarily for use in 4wds but can be used in boats.

      The Century here is a hybrid - it is not a pure deep cycle and it is not a pure standard battery either - and it is specifically designed to take the punishment that waves and engines hand out to batteries used in boats. It can do deep cycle tasks (albeit not as well as a true deep cycle battery), but it can also output big amps to start engines which is something normal deep cycle batteries aren't great at.

      Deep cycle batteries are designed to run things like lights. They are not so good at starting things like outboard motors which need big amps.

      This battery has 180 reserve capacity vs 105 for the Neuton. That means this Century has a higher total energy capacity. For my needs (starting outboards and running lights/radios/etc from the 1 battery) the Century is a much better option.

      You really need to determine first what sort of battery you need.

      • Cheers for that info.

      • actually, the marine batteries from century perform better as deep cycles than the deep cycle batteries do.
        the plate thickness in the marine are 2.1mm compare to 1.9mm in the deep cycle and 1.7mm in the standard cranking batteries.
        we used to fit a lot of marine batteries into Diesel 4WDs too like patrols and land crusiers. would handle the off road better than both the cranking and the deepcycles.

        they are a seriously well made battery and a generally cheaper than the cranking and deep cycle variants.

  • there is a place in Adelaide that sells these for $158.00 all the time.

    • You should post it as a deal. That is a very good price.

      • nah. too mmuch business and they'll up the price.
