  1. Simon Head (verified owner) –

    Again excellent price and first class delivery service. Went for the slightly longer battery life as we’ve got quite a lot of hedge to trim. It’s certainly a lot easier than cutting through electric cables when hedge triming at difficult angles.

  2. Jo (verified owner) –

    I bought this battery with hedge trimmer together, this battery is heavier than I expected, however it does last long time and charge quickly. So if you buy together with trimmer, it is better buy a universal shoulder strap together, it will certainly help your hands and arms.

  3. Alex Hill (verified owner) –

    Fantastic service, with same day delivery! Easy to navigate website, highly competitive price. Difficult to see how you could do better.

  4. Adrian Duckett (verified owner) –

    Waiting for rain to stop so I can use it.

    Needed another battery for my growing Stihl tools collection and Radmore tucker delivered it very quickly and the price was the lowest by a fair bit.

    Again excellent price and first class delivery service.

  10. Richard Chantler (verified owner) –

    Ordered new stihl battery, delivered quickly and was at a good price. No English instructions that I could find! Not an issue as far as I’m concerned. Charged and in use.

  11. Tony (verified owner) –

    Just when I needed it..perfect

  12. Beresford Paul –

    Very good piece of kit. Good price and excellent delivery service. Battery holds up well. Easy lasted 200m2 + of very long grass cutting with some left over. Very pleased.

  13. Mel Stokes (verified owner) –

    The Stihl AK20 battery I purchased was at a very good price and the overall service I received was excellent. Many thanks.

  14. Craig Brown (verified owner) –

    Used this on the RMA235 lawnmower, did all 3 of my lawns (small-medium sized) and still had 50% battery left. Also used it on HSA50 hedge trimmer and got loads done and used way less than 50%. Plenty of power for your average gardener.

  15. michael frederick clubb (verified owner) –

    best price i could find and good delivery time

  16. John Turner (verified owner) –

    I now have 4 Stihl batteries and I never run out of power. When one is working the others are waiting or on charge. The price was right and the delivery excellent.

  17. Mandy Orchard (verified owner) –

    Excellent service & a great product. Needed the more powerful battery for our leaf shredder/blower. Good price and fast dispatch.

  18. Chris (verified owner) –

    Great battery at a good price. The difference in performance from the AK10 is significant. The AK10 is only suitable for the lightest weight Stihl products (hedge trimmer etc).

  19. Gabe (verified owner) –

    A supplier that is dependable and easy to work with. Great website and simple to navigate. Excellent value, great and reliable delivery. Thanks

  20. Zaz (verified owner) –

    Good prices, promptly dispatched. Very happy.

  21. Ian M (verified owner) –

    Great battery with plenty of endurance compared to the AK10 version despite being somewhat heavier. I probably will not go down the AK30 route as this is sufficient for my needs. Recommended.

  22. Gail Levine (verified owner) –

    Amazing service, great price, next day delivery, I ordered on Friday received my Stihl battery the next day. Would definitely recommend.

  23. David T (verified owner) –

    I bought this as a second battery for my leaf blower – which is excellent – as the battery lasts about 40 minutes. This enables me to use the the blower continuously. I am very pleased that the battery maintains its power until it is exhausted.
