Nu-Tool codless drill won't hold its charge
I bought a cordles drill from Makro the other week. Brand name: "Nu-Tool". Admittedly it was cheap (£20, including two hefty batteries). But I've had other cheap Nu-Tool tools which have been fine. With this item, neither of the batteries seems to hold its charge. I've put both on charge for about 15 hours, and the drill will only run for about ten minutes before it grinds to a halt. Same applies to both batteries. Anyone else had the same experience with Nu-Tool cordless drills? This one is 24Volt and the output current of the charger is 2.5 amps. Thanks Frank |

Thanks Frank You have already stated the problem .... it was cheap. Buy cheap - buy twice. Lately NuTool stuff has become crap. |

Sounds like the drill I have, which I bought at Makro about 6 months ago. Runs like a good 'un, so I suspect you may have a charger problem with yours. Take it back - Makro's are very good about exchanges I've found. PoP --- If you need to contact me please submit your comments via the web form at http://www.anyoldtripe.co.uk. I'll probably still ignore you but at least I'll get the message..... :) |

I'm not convinced it's the problem in this case (as other posters have suggested it's possibly the charger) Do the batteries get warm at any time under charge (they may not if it's an 'overnight' charger)? I bought a 'cheap' cordless (24V) drill recently (to suppliment my DeWalt) but I made sure it had two batteries AND an auto charger. The batteries take a bout 90 mins to charge and the charge-from-flat-to-cuttoff time is a good indicator to how things are going. All the best .. T i m |

NiMH cells don't really like fast discharge, so are not the best choice in all cases. |

How many cycles, before a cell/most cells fail? Some power tools approach this sort of drain. |

NiMh cells are junk IMHO. |

Philosopher strung together this: NiMh cells go flat all by themselves in a few weeks. NiMh cells are junk IMHO. I had a fully charged NiMh cell left on the side hold its charge for 6 months. -- SJW A.C.S. Ltd. |

How many cycles, before a cell/most cells fail? [T] Em, not sure .. I was racing several sets all season (once a month, all year) at that pace and didn't have a cell fail? In fact in my 30 years or RC car racing (sponsered driver for some of that) I've never had a cell fail? I have seen others have cells fail, I've marshalled a car that just turned into a heap of glowing red wires in a matter of seconds but I've still got packs Nicad and NiMH that are a good few years old and are still going strong? The 'top boys' generally only run each pack once / day but at 50 quid a pack and possibly 8 rounds plus finals / race day *I* had to recharge all the time? Mind you, the 'pits' have changed quite a bit over the years .. looks more like a lab at NASA these days with all the digital delta peak / fan cooled charging stations and comm turning lathes .. ! (some folk actuallt strip the motor, skim the com, rebuild / lube the motor, solder in a new pair of brushes ..and solder the motor back into the model (connectors waste power) after EVERY 5 min heat! Some power tools approach this sort of drain. Ooo err .. The only other things I know that can kill a battery in no time flat are some digital cameras? All the best .. T i m |

Worked really well until one of the cells vented under full load. This resulted in one of the most impressive sinkings I have ever seen! Picture this tiny craft speeding along at 20mph - a loud BANG! - and craft transitions from that forward speed, to an instant vertical descent! Bit like a Harrier VIFFing in reverse! The release of gas from the cell burst the hull / deck joint almost the full length of the boat, starting at the bow - opening it up like a crocodile's mouth - spoilt the hydrodynamics a bit! -- Cheers, John. /================================================== ===============\ | Internode Ltd - http://www.internode.co.uk | |-----------------------------------------------------------------| | John Rumm - john(at)internode(dot)co(dot)uk | \================================================= ================/ |

I think the venting arangement on these cells is much better theese days! As I said, I have seen other folk get into trouble with cells and I've melted a pack in the old days before auto chargers. A mate had a cell explode in his 12th Electricar (back in the Ally pally days). The 'built in' packs would br run, be charged, run, be charged and as we had low club numbers at the beginning not enough racers to make more than one heat! (to give the cars a break inbetween races). All the best .. T i m |
