    I have a dead Dewalt FlexVolt 54v battery, can I use that as a trade in?

    • +1

      Excludes toy/replica/non-18V batteries.

    • -2

      That's not 18v

    • No reason why not, it's still an 18v battery. Might do the same I have a dead one too. 12ah cries in flexvolt

  • +6

    Great price on the Ozito 5.2 if you have a spare 2.5 lying around; works great for the lawn mower

    • In theory, same voltage should give same power. I think buying 4x 4.0Ah will last longer for the same price.

      • Not really. Depending on current draw you will get a lot of voltage sag with a battery that cant handle the higher current demands. Which means when the voltage sags due to excessive current the BMS thinks the battery is depleted prematurely.
        If you don't have any high current demand tools that you want to increase the performance of, 4 x 4.0Ah is ultimately a better bet.
        If you need the extra current though, there is no substitute.

        • Yes the 5.0Ah battery is better for high-drain tools, while the 4.0Ah is cheaper per wattage hour.
          The tool that can draw over 4A can benefit from that but not always. I don't think a coffee maker can make better coffee with a 5.0Ah battery.
          It should depend on the designed operating power.
          There should be specs sheets somewhere we can check. Unlucky I can't find one with my quick search.

  • I'm a little confused.
    There are currently 18v Ozito battery combos for <$20.

    Could I theoretically buy 5x of these, spend $100 then get $250 credit for other batteries?

    • sort of, but not as “credit.”

      So, if you brought 5× 18V batteries and bought 5× eligible twin packs, you could get $250 total taken off those five packs (i.e., $50 per pack). It’s not a general store credit and can’t be applied to other batteries/brands outside those two packs.

        I just read the full terms.
        Term 9) 9. Only one trade In Offer can be redeemed per one (1)18v battery that is traded in along
        with the purchase of one (1) Qualifying Product. For example, an Eligible Claimant
        cannot redeem more than one $50 discount for the purchase of one (1) Qualifying
        Product. But an Eligible Claimant can redeem a $100 discount (but no more) for the
        purchase of two (2) Qualifying Products if two (2) 18v batteries have been traded in.

        TLDR: They can only stack to a total of $100 for 2 Qualifying products or $50 per redemption.

        Cheers

        • So you just get family members to help you out!

          • @geekcohen: It's not THAT good of a deal… You receive a 28% discount… Conditional upon;

            $129 spend & surrender of 1x battery (if brand new, ~10% off overall, if dead full discount, half-worklife ~22% overall.

            Put me down for one, but more? (tracking down/communicating with family is enough to put me off)

            • +1

              @parad0x: Cant you just visit the store twice and goto a different counter?

      • You playing guess the terms of the offer?

        • No, it was just a general statement. Obviously there are terms about the max per person, but in theory it is all the same if you just spread it over a few family members.

          • +1

            @geekcohen: Probably might wish to generally state that you don't actually know this, but your math is solid - which is the sum total of assistance you provided by your "general statement; in theory",

    • Under $20? Source?

      But, no you cannot

      …, an Eligible Claimant cannot redeem more than one (1) $50 discount for the purchase of one (1) Qualifying
      Product. But an Eligible Claimant can redeem a $100 discount (but no more) for the
      purchase of two (2) Qualifying Products if two (2) 18v batteries have been traded in.

  • Do you guys know if it has to be brand for brand? I have an old 18v Ryobi one plus I want to trade for an Ozito

    • +4

      any brand of trade in 18v.

      • +1

        last time they even let me keep the old one .

        • -1

          Has anyone tried trading in 2 batteries for 1 twin pack? To get $100 off? Just spoke to two Bunnings stores and they're telling me you can only do 1 battery per twin pack?

          • +2

            @tanzy: Why not just read the terms mentioned multiple times above?

            • -2

              @m9: Believe it or not, I even pulled it up in store but they refused to budge… Even had 1 store saying it has to be brand for brand

              • @tanzy: Last time I traded a shitty 18v lithium battery from a supercheap auto branded carpet spot cleaner I converted to take ozito batteries and it was fine, although the staff member knew nothing about the promo and I had to show them the details then they found a staff member that knew a little about it.
                So maybe last time was a little more lenient?

              • @tanzy: Make a complaint. Ryobi has been very specific that ANY 18V battery is acceptable.

  • +1

    My 36V lawn mower runs on two 2.5Ah batteries, and it feels as strong as a bull. If I use two 5.2Ah batteries, will it be like a T-Rex?

    • +4

      No still like a bull, just a bull on Viagra that can keep your neighbours up all night.

      • +1

        Don’t put that last bit in a search engine

    • definitely. I don't have 2x of the lower to test in the mower, but when I use the 5.2 in the blower there is a noticeable diff compared to even the 4

    • +2

      the 5.2ah high output is a beast of a battery. I use 2 using battery adapters in my 36v Makita mower. that thing runs so much better than using the Makita batteries.

      • Would the 5.2ah give my ozito vacuum cleaner a bit more oomph?

    • Maybe not T-Rex only a Raptor for speed?

  • I have a 4amp Ozito that won't charge. Will that work for trade in?

    • Is it 18v?

      • Err….yes

    • +3

      Sometimes if theyve been left to go completely dead….the charger wont charge it. I had a couple of dewalts this happened to…almost new but left too long in tool. You can revive them by jumping off another battery for a couple of seconds. If yours is an old battery thats just been recharged a thousand times….then probably different situation

      • Jumping? Wondering how that works

        • +4

          Wire the batteries in parallel by connecting the positive terminal on the working battery to the positive on the dead battery, same with the negative terminals. You should use thick gauge wire for this. Ideally it'd be better to use a DC bench power supply so you can at least limit the current flow but paralleling the batteries should get you by in a pinch.

  • +1

    will these two (combined 10.4ah) give a longer runtime than 3x 4ah (combined 12ah) batteries in a lawnmower? mathematically it won’t but how is it in practice?

    • +2

      It actually could depending on the current draw demands of the mower.

      With the 5.2ah you would have less voltage sag so would likely use a lot more of a the usable capacity before hitting low voltage cutoff.
      If there is more demand for current than the 4ah's can supply it may suffer from enough voltage sag to trigger low voltage cutoff much sooner than it would in a normal demand scenario.

      Someone would probably have to test that theory in the real world though as I don't know how the mower in question responds to the battery current tapering off. Does it just start running worse and cutting grass less well? Or just cut out completely. If that's the case I would guess the 5.2ah batteries would keep it running at full power for longer?

    • +1

      A few other points I can think of are: (I have no actual practical experience with it though)
      - newer/better cells in the 5.2's
      - some tools are "36V" which take a pair of batteries (e.g. the blower, chainsaw, sliding mitre saw), so you get the capacity of the full pair

  • +1

    battery bin dumpster diving!!

  • +2

    Took in a 2.0Ah and a 2.5Ah with a broken prong (to it wouldn't lock into a tool) and got two packs. $100 saved. Looking forward to using them! No questions asked. The lady on the tool shop desk didn't really care.

    • +2

      I took in a dead 8 yr old 3ah and it was ytaded in no questions except that the cashier had no idea what I was talking about . Luckily the promo flyer was taped to the front of the counter .

  • +1

    Took a very old Bosch 18v that wouldn't charge anymore from the battery bin at work into Bunnings and he didn't even take the battery yet honoured the offer.

    If anyone in the Toowoomba area wants this old battery to utilise for this deal then it's all yours!

    Had a Bunnings worker tell me tonight that it was only select stores doing it, this wasn't one, and I would need to go to a nearby store. When I pushed back reading the conditions saying it didn't mention that, another worker told me it is because Bunnings stores were independent "like franchises".
    They ended up "honoring" it, as they had no real answers as to why they weren't doing it, but was just a weird all round experience.

    • Lol what?

    • which store was this?

      • Oxenford QLD, so not like it is some little store or anything either.

        • +3

          There is no such thing as bunnings franchise stores lol
          They are all Wesmfarmers owned, and this is a Australia wide promo.
          What a tool! Report him to his manager and the head office.
          I would have.

  • I get a set of these batteries and saved $50.
    Very happy.
    Thanks to the poster!

  • +1

    Just plugged this into a bosch biturbo leaf blower using an adapter. Very happy with the performance for $65

    • You can feel more power compared to the 4Ah battery?

  • Anyone has a spare dead battery in Perth?

  • Anyone know if they will accept a 40v battery?

  • Can't find a bunnings that will let me keto the battery

  • $40 each and I will stock some. Heavy bricks for rare use cases for me.
