  • 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.

      • Andy says:

        This is a design flaw – the circuitry drains the battery and locks out out – if you call makita and tell them your battery won’t take a charge, and especially if it is new – they will replace it under warranty.

      Can you give me some information on were i can buy new locks locks for my van vault ? I have had my van broken into twice in the past 18 months these people dont give a dam about anyone or anything they damage you van /car, take what they want leaving the working man unable to work & having a vehicle to repair plus the replacing of tooling (yes i am bitter) But so is every other tradesman,this has happened to.

      • 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?


      • DCI Solutions says:

        The HP457 is the newer entry level machine and is only compatible with the 1.3ah batteries supplied. You cannot use these batteries in any of the LXT range of machines.

    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. Mark says:

      Hi ive got a Makita BHP453 with 1.3ah battery, would the charger charge a 3.0 ah battery ok or do I need a new charger?

    7. sean douglas says:

      I have a combi drill with 2 Li 18v 1.3ah batteries and charger.
      I want to get myself in impact driver and i was wondering what Impact drivers are compatible with these batteries?

      • Richard Hughes says:

        Hi Sean,
        Do you know the model number of your Combi Drill? (its written on the side of the drill itself) if you let me know that i can make sure i know exactly what batteries you’re using and can help you better.


      • DCI Solutions says:

        As long as your drill driver is not a HP prefix model and has LXT markings then the BTD140, DTD146, DTD148 or DTD129 will fit the bill.

    8. Palm says:

      Do makita 1.3 18v batteries fit new 18v impact drivers, hammer driver drills? which i have 1.5ah batteries for?

    9. mike says:

      Hi, do the 1.3ah li battery’s fit the 18v heated jacket?

    10. Kevin says:

      I have a 14.4V set came with lights impact and drill. Has 1.3 AH batteries that came with it. Will the 14.4 3.0 AH batteries work with them and my charger?

    11. ted garvey says:

      These 18v look alike Makita batteries do seem 2 do the job ok and discharge at the same rate : So far so good their still on my trial ! LOL

    12. Dave says:

      Hi, I’m trying to find out in dewalt tools can fit both 3 amp and 4 amp lithium ion batteries? Thanks

    13. Laura says:

    14. Rob says:

      Hi can anybody offer any help? I recently purchased a cordless impact driver TD127D and Cordless hammer driver drill HP457D along with two 18v Li-ion batteries BL1813G. Am delighted with products BUT am frustrated because the batteries do not fit either my DAB radio or recently purchased rechargeable job site light BML184. Am I being a thickie? Why are the batteries not compatable?

      • DCI Solutions says:

        The kit you have is the entry level range of machines and not part of the LXT family. These two ranges are not interchangeable.

    15. billy says:

      I was wondering if the old style red pa18 2.0ah battery and the pa18 1.3ah will fit the same drill thanks.

      • DCI Solutions says:

        All 18v plug in makita batteries will fit the same machine whether they are 1.3ah, 2.0ah Ni-Cd or 2.6ah Ni-Mh.

    16. Barry smith says:

      I’ve bought a makita job site dab radio can you tell me what battery I need it has a yellow slot for it to go in

    17. Gary says:

      Hello Richard! (or anyone else who has advice on this subject)

      I had recently bought the makita cordless reciprocating saw and circular saw, (because I already had the impact driver and drill+batteries) from a few years ago but i seem to have picked up the wrong battery as an extra. So I have 1 battery that has 1.5Ah/27wH and 2 that have no aH rating/24wH…. The 1.5 aH however, fits the 2 saws, but the other 2 do not. All charge with the same charger. So my question to you would be is it unsafe to modify the batteries so that they will fit in these saws? It would only involve removing a bit of plastic and not doing anything to any of the conductive terminals… Judging by the article the 1.5aH shouldn’t even fit the saws anyways, but seeing as it does I can’t see how trying to get the other, older batteries in there would be dangerous, it should just drain them faster? Am I off my rocker er what?

      • DCI Solutions says:

        It appears you have two 1.3ah batteries designed for the newer entry level drill driver. I would return and exchange them, any modifications will invalidate your battery warranty.

    18. Dave sutherland says:

      Hi guys, I have a drill and impact driver which were supplied with bl1813g batteries 1.3ah
      I’m looking to get a cordless circular saw and would like all the batteries to be the same…. Say 3-4ah but I am totally lost at which saw to get that will have compatible batteries for my drill and driver,, any advice would be appreciated!

    19. Robert Chenery says:

      Hi I have a Makita TD127D 18v Impact driver with a BL1813G 1.3Ah battery can I get a bigger Ah battery for it .

    20. Ben says:

      which of the makita impact drivers will run of a 1.5ah 18v li ion battery? Looking to buy a body only deal or possibly with a single battery.
