  1. Every year at work they change the batteries for the back-up system in the Servers at work. out of 20 or so I'll get 4 or 5 that are still good. I check the voltage, and see if they will take a charge using my CETK Charger (which has a 'reconditioning' function) if they take and hold a charge then I load test them (usually with a 20W bulb) then re-check the voltages. i then put them on a 12V tyre pump and see if they will blow up a tyre (car tyre) With my 'current' batch (did you see what I did there?) I got them down to ten number with a range of 12.8 to 13Volts, 4 passed easilly blowing up a tyre. the other 6 despite showing a good voltage just crashed when I did the bulb test (showed as 0.01V with the 20W bulb across the terminals) I havnt encountered this before - advice and explanations would be very welcome. They are quite small, not quite as big as a motorbike, golf cart, or a jump starter battery, but using 4 toghether you can use it as a jump starter. Also very handy in the camper as the lesiure battery, individually with the 12V tyre pump (wheel barrows, mowers) and jumpstarting mowers. below is one Ive bodged-up with copper pipe 'horns' for the jump leads, a 50A Anderson connector, and cigarette lighter socket. (I'll admit I'm a bit 'tight' - and if I took my time into account - it would have been way cheaper to buy a jump start pack) Thank you
  2. Hello Boys and Girls out there in Land~Rover land. I have,what I think at this time of yaer,a common problem. Battery won't start my Defender!! During very cold weather I am yet again experiencing trouble starting my Defender after a cold night or a day or so without use. The engine turns over but will not start,then it just dies out,leaving me to get my wifes tiny Mazda MX5 to jump start it,which it does instantly. Under the front passenger seat there is the usual battery,plus two leads for an extra battery,possibly used in its previous life as a Police vehicle,which it was when first registered back in 1992. My question/s is/are ... what is needed if I was to decide to use two batteries thus giving 24 volts for use of extra toys in the future or perhaps a caravan etc? do I have to fit an extra alternator? is it the norm' to have a switch for using/switching over to either battery? does having two batteries mean that it is only possible if you have a 24v set up? and also am I talking a load of rubbish and the problem can be solved by purchasing a brand new battery because that's what everyone does as it's common knowledge that if it won't start,the battery is a gonna? Any help you can give on this matter would be very appreciated as I really have no experience of,or information about batteries. Thanks in advance for any ideas you can share, Kev English
  3. I'm installing some 24-volt gear in my 12-volt 90TD5. It potentially needs a standing current of about 1Amp, but can intermittently peak to about 16A. So far the only option I've been able to come up with is to stick in a second battery in what amounts to a split-charge system but with a couple of DPCO relays which then hook the 2 batteries in series when the radios are in use. Does anyone have a better suggestion? A 12V to 24V sine-wave inverter would be an option, but it would have to be one which generates very low levels of interference/RF-noise. --Tanuki.
