This of course is theory but it would not be unreasonable to expect about a week from the support battery and at least 3 months from the 'van battery.Ī solar panel of reasonable size should be able to keep everything happy, even if the caravan battery is removed. Assuming a fully charged 110Ah caravan battery then the unit should be happy for something over 20 weeks. If the device draws 30mA then a 7Ah battery fully charged should, in theory, support it for something over 200 hours or at least a week. Fortunately I had a spare (they are easily obtained from such as Maplin or CPC) which when fitted restored normal service. In my case the thing stopped working and when I found out where it was I discovered the 7Ah battery was cooking and its case distended. There is also a 12V 7Ah gel lead-acid battery (as used in large burglar alarm systems amongst other things) that provides the main supply and this is in effect in parallel with the caravan battery albeit protected by a diode to stop reverse current flow. Lithium cells have a typical life of five years and a shelf life of at least double that. The 'back-up' battery so called is a lithium cell that retains the config. Perhaps I can offer a bit of help as (a) I am an electronics engineer recently early retired, and (b) I had a battery fault with my Tracker and I know where it is! Only the tracker alarm can activate the tracker unit by the key fob all others hal locate, sure-track and the non integrated Phantom are armed by the helpdesk If they are integrated then all it is is a sensing wire coming from the alarm output to the tracker unit, but most tracking units have an internal movement sensor and are armed separately from the alarm and activated by calling a help desk.Īgain i would like to display the info from tracker that comes with the Baileys tracker info pack: The above is incorrect as Tracking units are stand alone units and are hidden somewhere in the van,some have a 12v supply, but its not to charge and when this is lost it reverts to its internal battery which has a 3 year life.Its the alarm that has a separate 12v rechargeable battery. A tracker has 2 batteries, one is 12 volts and is kept charged by the caravans leisure battery, this battery powers the alarm which is part of the tracker system and also the tracker itself, there is also a 6 volt non chargeable battery which will power the tracker in the event of the leisure battery going flat followed by the trackers own 12 volt battery, the 6 volt battery will last for years so long as the leisure battery is kept charged, if the leisure battery go's flat and the tracker 12 volt battery does the same as a consequence of this the 6 volt battery will go flat probably within a week, if the leisure battery is charged before the tracker 12 volt battery is flat it will then recharge and the 6 volt will not have been discharged at all, a tracker current draw is 2 milliamps so on its own a tracker would take ages to flatten the leisure battery, both the 12 & 6 volt tracker batteries can be replaced although its highly unlikely the 12 volt will need changing as putting th caravan on EHU will soon restore it to fully charged.Ĭlick to expand.
