I put my battery on last night to charge up. I always leave it overnight and turn off the socket before work in the morning to use later in the day (so I would never usually just pick the battery up)
This morning I forgot and just went to get the battery and was a bit concerned that it's red hot. Is this normal?!
I've had them about 4 years and have never noticed it before but like I say usually just flick the switch off and get it later so possibly giving a chance to cool?
But worried!
 
The Liberty battery does get "warm" when charged. The charger likewise. Obviously,there is "hot" and "hot"! I always recommend not to leave on more than overnight, say 12 hours and to ensure the battery is run low before re charge. The overheating,may be an indication that one of the cells is starting to fail. Check if you start to get less clipping time when using? Also, maybe,just charge and run flat a couple of times and see how it goes. I would also advise, that when charging anything, you always charge the item, (be it mobile phone or clipper) somewhere safe. Where is for some reason the battery does catch fire, it will not spread. This has no reflection on the Liberty battery, just any battery being charged, will heat up and you never know. The guys who use lithium ion batteries for radio controlled planes use fireproof bags to charge them in...for a reason. Good luck.
 
Thankyou for replying!
I don't normally leave them that long and won't again just in case.
I only needed them this time for a tidy up pre- comp but will definitely make sure I charge them somewhere safe (a tiled floor?) and will also run the battery flat at the next opportunity.
Thanks again
 
Ah, it seems TheEngineer speaks with authority. Good!

We also have a set Lister Liberty clippers, and from new, the battery would trip out but only at the point of charging. Sometimes the reset button would click in when pressed, and sometimes not. I 'phoned Lister, got one of their technical bods and he said that they'd had problems with the batteries and that he'd send me out a small part (can't remember what now!) for me to replace. I did, and it worked a treat, until now and the same problem has returned, the reset button doesn't click in. I must stress that the clippers are fine in use, the problem only occurs when an attempt is made to charge the battery.

We have a friend who has an identical set of clippers with the identical problem! Are small batteries prone to such disorders and would it make more sense for me to buy a £28 adapter and run the clippers off a car battery?

I'd be grateful for your advice.

That's interesting.
My US version trips out when charging in hot weather - like anything over 85F (sorry what's that in C?) which means I have to have them indoors where the a/c's on the charge the battery in the summer
I've had them a few years now and I think the battery isn't holding charge properly now anyway
Anyone know how long they last?
 
Thanks JDee, and it's a point which I've wondered about.

I've now just taken the offending battery, and stuck it in the fridge. I'll wait for an hour or two, and see if it has any effect! :D

I'll report back.

Interesting comments about lister liberty batteries. I have had mine for 3 years and the battery isn't holding a charge. When I phoned the supplier they told me lister didn't guarantee any of their batteries!!! I've now bought a mains lead as replacement batteries are anything between £119 and £150 - seems rather expensive for something which has no guarantee. The clippers are great when they work but the battery replacement cost seems excessive even for the benefits they give.
 
I run mine from a car battery, the lead is inexpensive and I have no problems doing several horses in one go, when I bought them many years ago it seemed the best option as they get a fair bit of use.
 
Mine are now 11 years old and two years ago my OH replaced the battery pack by buying the individual cells and soldered them together. A lot cheaper than buying a new battery pack and think cost under £50 for everything.
 
The Lister battery does seem to either last for ever,or last for never!!! Lister were looking at a new Lithium Ion battery, but as of yet, I have not heard it has gone on sale. The reset switch can cause problems if the wires inside have worked loose, try undoing the two small cross headed screws that hold the battery pack on and inspect the wire connections on the back of the three pin din socket. If you need a replacement socket, I suggest Maplins, rather than buying from Lister. They are a standard audio type din plug, so available cheaper. The other thing to check,which I have seen many times is the Din plug. Both on the charger lead and also the one that connects the clipper. The wires pull back through the strain relief and twist,this causes the wires to short out. So that is always a worthwhile check. Obviously faults in the battery can also cause problems. A 12 volt battery lead kit is available, so you can run from a leisure battery and I have seen several very clever people make their own battery packs using something like this

As a genuine Lister battery alone is near on a hundred pounds. A little tech skill can save some cash. I would say, check all your wires on connections first. Then if reset keeps tripping, if you can, try your clipper on a known good battery. At least this will tell you if problem is clipper or battery. Failing that, send it to Lister, c/w your charger and clipper, so they can test it.
 
Thanks for all the helpful posts - and to the OP for starting this thread!!!
I had the battery on charge on Thursday - didn't trip it but the clippers only ran for about 20 minutes then started to fade
A new battery pack is around $134 here, seems a lot.
I don't really want to go back to having a mains lead trailing around - I'll show my husband some of the replies as anything too techie goes right through my head!!
