Review: AWESOME DEAL AT 12.50 FROM ACTUALLY desertcart - AWESOME BATTERY, WELL MADE, FAST CHARGING AND VERY LONG LIFE, I AM SO HAPPY WITH MY BATTERIES, WELL WORTH THE MONEY I PAID, WELL DONE desertcart FOR GIVING US SUCH A GOOD DEAL ON THESE BATTERIES. desertcart YOU MADE MY DAY WITH THIS FLASH SALE. THANK YOU FOR HONOURING THE DEAL. When i spotted these at just £12.50 2 weeks ago i thought it was a scam or a mistake but the seeing they were being sold actually from desertcart and not a 3rd party and with prime i decided to order 20 or in the end all of the last 11 which was listed as available stock, WOW what a deal 11 YES ELEVEN 4 amp batteries for under £140 in grand total i could not believe my luck or eyes, i was given a delivery date of about 30 days but they all came today 2 weeks early and are 100% genuine dewalt boxed batteries, i see desertcart later had put the price up by over £40 to £53 each before removing them completely from sale by desertcart themselves, so i think i managed to get a flash sale or a clearance just in time, however these are not even old stock as the manufacturing date is only a month ago so i am so delighted with this deal, i am currently charging them all up to check them out but the are 100% genuine delwalt retail boxed and direct from desertcart themselves, funny thing is i only wanted 1 battery for a backup tool at the time of sale as i stopped using dewalt in favour of milwaukee some time ago, so i currently only use a dewalt impact as a backup tool only, so this deal might end up costing me a lot a i will now have to invest in some more dewalt tools to take advantage of my new pile of batteries, lucky i kept my old dewalt chargers to charge these bad boys. so far every battery is 100% good and fully charged, just tested my impact driver and its so powerful compared to the old 3 amp battery, and i pounded in some 8 inch torx screws no problems what so ever into sleepers. well i am delighted anyway these are good strong batteries indeed as good as my milwaukee 5 amp batteries, you guys keep your eyes open for other deals as at £12.50 this was fantastic value for money, not sure how many people grabbed these at £12.50 each but i know i got the last 11 as i tried to buy 20 and they would only let me buy 11 thank you desertcart
