[QUOTE="chrisc, post: 770678, member: 746"] There is a problem with trickle chargers since they continuously apply current to the battery and this is not condusive for long life Paradox alarm panels can frequently resurrect (fairly) flat battery by applying a high voltage for 60 seconds, removing the charge for 8 seconds, measuring the drop and reapplying power. Over a 24 hour period, this will successfully restore a battery which has gone down to 10 volts You get "intelligent" battery chargers which operate in the same way, using a microprocessor to measure the battery condition and adjust the charge rate and time. When the battery gets to about 13.5 volts, the charge rate reduces substantially Well worth a buy to keep batteries running I have met the blonde lady at Milnerton and always take a meter and a 20 watt lamp to check the batteries since some are useless, and they are indistinguishable from good ones. She knows that some of the batteries are duds but puts them on sale just in case [/QUOTE]
