Jellybean Posted August 3, 2015 Share Posted August 3, 2015 Out of curiosity how long does your battery last with the alarm on ? Mine dies after about 10-12 days , halfords battery, 2-3 years old Quote Link to comment Share on other sites More sharing options...
downimpact Posted August 3, 2015 Share Posted August 3, 2015 disconnect when not in use then, no point letting it go flat shortens the overall battery life keep recharging. Quote Link to comment Share on other sites More sharing options...

Mine dies after about 10-12 days , halfords battery, 2-3 years old Mine doesn't even last that, usually about 5-7 days but mines on a trickle charger so doesn't matter Quote Link to comment Share on other sites More sharing options...

Admiral Donuts Posted August 3, 2015 Share Posted August 3, 2015 I usually let mine run for a bit if I'm not using it but I bet my neighbours think I'm mad lol Quote Link to comment Share on other sites More sharing options...
Jellybean Posted August 3, 2015 Author Share Posted August 3, 2015 It's more so because I was on holidays. , pita to come back to a flat battery Taught it might be the brand of battery as all my family's cars worked fine Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted August 4, 2015 Share Posted August 4, 2015 Mine usually lasts about 5 weeks before it goes flat. The longest I have left it was 6 weeks and it kicked over. Unfortunately I did leave it for 7 weeks and it was flat. It has since decided even after a slow charge that it won't retain a charge. So I need a new battery. I'm thinking about a Optima yellow top, purely because they are robust and can handle repeated total discharges. Quote Link to comment Share on other sites More sharing options...
David P Posted August 4, 2015 Share Posted August 4, 2015 I have a solar panel in the rear window of mine which keeps the battery topped up. http://www.ebay.co.uk/itm/Powerful-12V-Portable-Solar-Panel-Battery-Charger-4-5W-For-Car-Boat-UK-New-/111564288803?hash=item19f9bff323 Quote Link to comment Share on other sites More sharing options...
mellonman Posted August 4, 2015 Share Posted August 4, 2015 depends on what amp battery you have as well, but I would say a 3year old battery lasting 10-12 days with an alarm is not too bad , but alarm depending as I have a proximity alarm which goes off everytime someone goes near it draining mine even more .

fastcar Posted August 4, 2015 Share Posted August 4, 2015 Mine last about 3 weeks with the alarm on! I thought it's was just my car playing up and had a drain somewhere! Quote Link to comment Share on other sites More sharing options...
inazone Posted August 4, 2015 Share Posted August 4, 2015 I have an optima Red Top, my car lasts a couple of weeks without the alarm on in my garage. Have to keep a trickle charger attached. Quote Link to comment Share on other sites More sharing options...
Thomas.B Posted August 4, 2015 Share Posted August 4, 2015 I'm probably gonna remove my whole alarm as its so sensitive and goes off all the f-ing time even when I've lowered the sensitivity setting to the lowest. I never have the battery connected anyway so the alarm really doesnt do anything lol Quote Link to comment Share on other sites More sharing options...
trebor69 Posted August 4, 2015 Share Posted August 4, 2015 LOL longevity.....mine's a Bosch and has been on the car since I got it (3 years), longest I've left it is three weeks and it still turned over and fired up no problem. If you use your car regular then your battery will last longer/be stronger than if left for longer periods. Quote Link to comment Share on other sites More sharing options...
mwilkinson Posted August 4, 2015 Share Posted August 4, 2015 A battery, even with alarm should do at least 4 weeks. I can only assume a few of you have power drains somewhere. If your alarm installs are anything like the two I have inherited I would look at these first. I had my brother reinstall the Clifford alarms on both my cars as they were so badly done. Luckily for me he's an Auto Electrician Quote Link to comment Share on other sites More sharing options...

mwilkinson Posted August 4, 2015 Share Posted August 4, 2015 Can you ask your brother if its worth checking the drain on the battery with the alarm on , and what is acceptable Yes you should do that. That's what he did on mine. I'll ask him now about a reasonable figure for the drain and get back to you. Quote Link to comment Share on other sites More sharing options...
paulj1 Posted August 4, 2015 Share Posted August 4, 2015 Mines just done 8 weeks still started first time it's got Halfords battery on it and it's about 3 years old alarms a laze line 996v2 Quote Link to comment Share on other sites More sharing options...
Jellybean Posted August 4, 2015 Author Share Posted August 4, 2015 Yes you should do that. That's what he did on mine. I'll ask him now about a reasonable figure for the drain and get back to you. Looks like its 50MA http://www.mkivsupra.net/vbb/showthread.php?237136-People-with-Alarms-specifically-the-Clifford-650/page2 Mine is a 650MkII, but the current draw shouldn't be much (if any) different to the original 650. When the alarm is activated and the sensors have come on, the total drain on the battery (including whatever the head unit, internal clock etc takes) is 53 - 63mA. The variation will be down to the flashing alarm LED and probably also the way some the four sensors work. When the alarm is in 'valet' mode the drain is 43mA steady. When the alarm is off and starting is immobilised (sensors are not activated), the drain is 37mA - 43mA (varies due to flashing LED).

He has just come back with 50Ma or 0.05 on most multimeters. Quote Link to comment Share on other sites More sharing options...
