    How to choose a power tool battery


    Drill batteries won't hold charge? It might be time to buy a replacement battery! Without a battery, your cordless screwdriver or drill would be completely useless, which is why it's important to take care when choosing a replacement battery.  
    What voltage, technology and capacity should you choose for your replacement power tool battery? Which battery charger is compatible with your power tool battery?  
    The tips below should help you choose the best possible replacement battery to improve the run time and performance of your power tool, to let you get on with the job at hand! 


    Finding a compatible power tool battery on our website

    The quickest and easiest way to find out which batteries are compatible with your power tool on our website is to take note of the different references which will allow you to find the the battery you need: 

    • The brand and model of your power tool: for example, Bosch PSB VE-2, Milwaukee M28, etc. 
    • The Part Number of the battery: il the part number can be found on your original battery. For example, 2607335275 (Bosch), 192598-2 (Makita). 

    You can also type these references directly into the search bar at the top of the website or use intuitive brand/model search engine!

    If you still have any doubts, read on for more information or contact us with your questions directly.

    Which battery technology should I choose? 


    Three main technologies are commonly used in power tool batteries: Nickel-Metal Hyrbride (NiMH), Nickel-Cadmium (NiCd) and Lithium-ion (Li-ion).


    NiCd batteries are what we might refer to as 'older generation' batteries. NiCd batteries are generally heavier and take longer to charge. 

    An EU ban on NiCd batteries has made it illegal to sell them in the UK, but no need to panic! We can replace your current NiCd battery with an equivalent NiMh battery.

    Much lighter than their NiCd counterparts, NiMH batteries are often used to replace older NiCd batteries. NiMH batteries are, however, sensitve to self-discharge and deterioration linked to memory effect.
    Li-ion technology is a much more recent development and li-ion batteries are nowadays used in a wide range of devices. Li-ion technology offers a wide range of advantages, including long run time, light weight and durability - the perfect technology for your power tool battery. 

    CAPACITY: 1.4 to 2Ah for standard NiCd batteries


    CAPACITY: 2.1 to 3Ah for standard format NiMH batteries


    CAPACITY:1.5 to 5Ah for standard format batteries


    • - Quick, easy charging
      - Long life expectancy

    • - High self-discharge
      - Memory effect
      - Polluting (cadmium)
    • - Higher capacity than NiCd batteries
      - Weaker memory effect than NiCd batteries
      - Less polluting than NiCd

    • - Self-discharge
      - Memory effect
    • - In general, higher capacity than NiMh batteries 
      - Low self-discharge
      - No memory effect
      - Lightweight
      - Built-in circuit protection

    • - More expensive
      - Sensitive to deep discharges
      - Difficulty balancing voltage - require a PCM (Protection Circuit Module)


    What do the terms "Voltage" and "Capacity" mean?
    • Voltage: measured in Volts (V), voltage determines whether or not a battery is compatible with your power tool. The voltage is the power required by your power tool in order to operate correctly. If your power tool requires 24V, you must ensure that the voltage of the power tool battery you have chosen is also 24V. 
    • Capacity: measured in ampere hours (Ah) or in milliampere hours (mAh), a battery's capacity determines its run time. The higher the battery capacity, the longer the run time of your power tool battery. 

    Tip: You can calculate the overall power required by a device by multiplying capacity by voltage. E.g. for a 24V 3Ah battery:  24V X 3Ah = 72 Watt-hours (Wh)

    How to look after your power tool battery 


    Although we advise completely discharging NiCd and NIMH batteries before recharging them, this is not the case for lithium batteries

    In order to improve the battery life of your lithium battery, we advising not discharging it to less than 10% in order to avoid wearing out battery cells. 

    With regards to storage, it is best to store your power tool battery in a cool, dry place if you do not intend to use it for an extended period of time. Extreme cold or warm temperatures are not advised if you wish to keep your power tool battery in a good condition.

    How to choose a power tool battery charger




    Choosing a suitable power tool battery charger is important if you want to get the most out of your power tool. The advice below will help you choose a suitable cordless tool, screwdriver or drill battery charger

    • Voltage: the power tool charger must be compatible with the voltage of your battery. In general, a battery charger can be adapted to charge a variety of voltages - make sure you check the different voltage ranges indicated in our charger names!
    • Charge current: control the speed at which you power tool battery is charged. The higher the charge current, the quicker your battery will be recharged. For example, a 2A battery charger is capable fo recharging a 2Ah battery in one hour and a 4Ah battery in two hours. WARNING: in order to protect battery cells, we advice choosing a battery charger with a higher intensity (Amps) than the capacity of your battery
    • Technology: the technology (NiCd, NiMH or Li-ion) the charger is compatible with is indicated on all our power tool chargers. If you wish to keep your original charger, make sure it is compatible with the technology of your new power tool battery as many older chargers are only compatible with NiCd batteries. You may need to buy a replacement battery charger. 
    • Type of battery: there are two main types of power tool batteries:


    1. "Slide" batteries and compatible battery charger

    power-tool-battereis power-tool-battery

    2. "Clip-on" batteries and compatible battery charger 

    power-tool-battery power-tool-battery
    • Brand: whether you are looking for an OEM or simply a compatible battery charger, you will need to know he brand of your power tool (Dewalt, Black and Decker, Bosch, etc.)
