  • What Is The Difference Between 1.3Ah & 3.0Ah Makita 18v Batteries?


    We have had a lot of customers ask us just exactly what the difference is between the Ah rating on batteries for cordless tools and in particular the 18V Makita batteries.  A common question is: “Do all Ah ratings power all cordless power tools?”

    We’ve put this guide together to help you choose your cordless tools wisely as a follow up to our popular “Comprehensive Battery Guide”.

    The Ah rating is what determines how long your battery will last per charge. It stands for ampere-hour and is the measurement of time it takes for a battery to discharge. It is impossible to give battery run times on most cordless power tools as the variables of different working applications can change this drastically; however, the more amp hours, the more run time – like having a larger fuel tank.

    This is a major point to take note of when choosing your batteries – if you intend to use your batteries for more demanding tools such as Jigsaws, Circular saws, SDS+ Hammers, Planers, Reciprocating Saws and other high drain tools such as Grinders, then a higher amp-hour battery is essential.

    Makita have even made a different fitting for their 1.3Ah and 3.0Ah batteries to the tools so that the 1.3Ah batteries physically will not fit onto tools classed as high drain. Any Makita 18V Li-ion tool with a “YELLOW” battery fitting will fit both 1.3h and 3.0Ah batteries; however, tools with a “BLACK” battery fitting will ONLY fit 3.0Ah batteries.

    Please see below for the differences:


    The below diagram highlights the compatibility of a selection of popular Makita cordless power tools classed as high drain.


    Please note, there ARE a number of Makita bodies which are compatible with both 1.3Ah and 3.0Ah 18V Li-ion batteries – these tools will have the yellow fitting for the batteries.

    We offer a great range of Makita kits with Makita 18V 3.0Ah batteries as standard and also at the moment are offering a fantastic deal on the popular Makita BHP453RFE (which comes with 2 x 3.0Ah Li-ion Batteries) and for a limited time only, comes with an additional FREE BHP453Z Hammer Drill/Driver body.

      Hi , I have 5 of the 18v battery’s that won’t take a charge , I heard that you can fix them by changing one or two of the cells inside the unit , is this possible and how , thanks Tony.

      • Richard Hughes says:

        Hi AJT Joinery, I have seen the same things around the internet about playing about with the cells and to be honest it’s not something that i’d ever recommend. Lithium ion batteries are very dangerous and have in the past been known to catch fire etc, so if you were to make the slightest mistake it could go very bad very quickly. If you’re having problems with you Makita batteries then we have a dedicated Makita customer service phone line solely got ITS customers that you can ring. its 0800 345 7942 just explain your problems and they’ll be able to help you more than anyone.

      • Chris says:

        I had the same problem. I purchased a lithium 18v battery charger and charge them on that. It works. I had two batteries that would not charge on my makita charger, making them useless. I researched on youtube and a young guy goes through the process. It really works.

      • Richard Hughes says:

      Weirdly my bhp453 has a yellow battery fitting but only 2 pins not 3 like the picture!

      Also the batteries from my hp457 which are 1813g do not fit my bhp453 and vice versa!

      So what batteries can I use with my bhp453 and why aren’t the batteries between the drills interchangeable?


    4. David says:

      Will the 1.3ah battery work in the dab radio?

    5. Kyle says:

      I’m looking at buying a Mikita 18v 1.3ah drill and impact driver. If I the buy a 18v 3ah battery will it fit?

      • Richard Hughes says:

        Hi Kyle,

        As long as its part of the ‘lithium-ion’ family then it should yes. If you let me know the model number of the drill you’re looking at I can let you know for sure if it does.


    6. craig dunbar says:

      Could you please tell me which battery will fit the makita DHP453 RFTK

    7. Pete says:

      I have a Makita HP457D Drill Driver, bought around Xmas 2014, which came with two BL1813G 18V 1.3aH batteries. It has a BLACK fitting for the batteries, although there is an extra contact compared to the ones shown above. Sweeping statements like ‘Black fittings only take 3aH batteries’ should be taken with a pinch of salt as the saying goes.

    8. Callum says:

      will my 18 v BL1813G battery fit DTD146Z model

      • Richard Hughes says:

        Hi Callum,

        I’m afraid not the BL1813G batteries were designed to be sold in national large DIY stores and therefore only fit the tool you brought it with. The professional standard DTD146 requires either the BL1815, BL1820, BL1830, BL1840, or BL1850 batteries

    9. david murphy says:

      Hi can u tell me if I can get a makita radio that will take my bl1813g batteries

    10. Simon says:

      Hi there,
      I am a occasional home DIYer but would like a cordless drill so I can be impulsive without getting extension leads out etc. I think a 1.3ah battery will suit me fine but do they hold their charge over the course of weeks when not used? Or do they drain?
      Many thanks,

      • Richard Hughes says:

        1.3Ahs aren’t a bad bet for a DIYer to be honest. Lithium batteries are far better at holding their charge than the old NiCD or NiMH batteries. Thats not guarentee that they’ll keep their full charge but if when you put it away its got anything more than full charge then you’ll still have plenty of juice left when you next pick up your tools.

    11. m hilmy says:

      My makita drill model 6279D 12v
      comes withe 1.3ah battery and woukd like to buy 3.0ah battery for the same drill is it ok and it will fit
      Withe out damaging the drill
      Many thanks

    12. Rob says:

      Hi I have a td127d with a 1.3 battery but I want to know if I can get a larger battery like a 3ah but not sure we’re to get it as the fittings are different

      • Richard Hughes says:

        Hi Rob,
        I’m afraid the TD127d wont accept any larger batteries as its a Bespoke DIY package created only for national DIY stores and not for the trade. This way it only accepts the included batteries.

    13. Lee says:

      Will it give me more power to the drill if I get a 5.0 ah battery instead of my 18v 1.3 ah ?

      • Richard Hughes says:

        Hi Lee,

        No a higher Ah battery will give you longer runtime but not greater power. So where a 1.3Ah battery will last say… 1 hour of constant useage, a 5.0Ah could last 3 hours… Thats kind of the idea.

        Hope this helps
