Brazil Posted October 3, 2010 Share Posted October 3, 2010 Hi guys, My optimus yellow top battery was dead after returning from a 5 weeks trip. I tested if the car´s altenator was charging before buying a new very expensive optimus red top battery. I´ve had it in the car for about 1 week and today when I went to start the car it was dead I got it going by jump starting it in reverse. There was a storm last night and there was a lot of rain do you think the rain is pouring in from the vents on my bonnet and messing up my eletrics? has anybody has had this problem before? Many Thanks Quote Link to comment Share on other sites More sharing options...
j_jza80 Posted October 3, 2010 Share Posted October 3, 2010 Check the battery terminals. Could also be an earth problem. Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2010 Share Posted October 3, 2010 I've read and heard a lot of horror stories about optima batteries. I have a red one and I'm not sure if it has given up the ghost too (under warranty though). If they are left to die, it can be hard to bring them back to life again.

Morpheus Posted October 3, 2010 Share Posted October 3, 2010 Hi guys, My Optima yellow top battery was dead after returning from a 5 weeks trip.

Many Thanks Yeah, sounds like a short to ground. High humidity and obviously water will leak the power somewhere eventually. I had my Optima red top in the Supra and it would run low after a few days of short trips to work and especially if left standing for a week. The alarm will drain it too, of course. From being almost unable to crank the engine, it charged right up after a 10 mile drive and the charger said it was full within a few seconds of connecting it. Perhaps these batteries are best for regular long journeys, despite the deep cycling claims? I'd say that your alarm is the culprit. Have you got a microwave proximity sensor? My Sigma S30 has one and I reckon it must drain it a fair amount. Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 3, 2010 Share Posted October 3, 2010 I can leave my Toyota supplied battery for a month and the car turns over and starts no problem. Quote Link to comment Share on other sites More sharing options...
Scott Posted October 3, 2010 Share Posted October 3, 2010 I can leave my Toyota supplied battery for a month and the car turns over and starts no problem. I couldn't do it with any battery I have had. Alarm with microwave drains it in a week... maybe just over. Red top doesn't last any longer surprisingly.

Guest blueangel Posted October 3, 2010 Share Posted October 3, 2010 my yellow top is drained too its been barely used for ages now but i need the sealed battery as its in the boot now, it also wont take a charge so im guessing its proper dead lol Quote Link to comment Share on other sites More sharing options...

Thanks for that, what's your address and are you out for a few hours? Don't worry, I'll bring my own battery and leads! Quote Link to comment Share on other sites More sharing options...
Brazil Posted October 3, 2010 Author Share Posted October 3, 2010 after i bumped started it and went for a 30mins drive it has been ok... i think the huminity is the big couse of it though my yellow top was dead to the world. Quote Link to comment Share on other sites More sharing options...

Scott Posted October 4, 2010 Share Posted October 4, 2010 Yes Hmm, it would appear I have a current draw from somewhere then. I have had a stock battery, a calcium battery and now a red-top Optima. All very similar lifespans when left in my garage for a week or 2. Quote Link to comment Share on other sites More sharing options...

All very similar lifespans when left in my garage for a week or 2. My old Toyota battery used to last a week and then be totally flat, no dash lights anything. I checked the alternator etc then fitted a new battery supplied by Toyota, the last time my car was left without being run was for approx 3 weeks and it fired up no problem.

Matt H Posted October 4, 2010 Share Posted October 4, 2010 After market alarms are a nightmare for eating the juice. This can often be the problem if left for a long period. Cheaper alarms tend to be the culprits. Quote Link to comment Share on other sites More sharing options...
Terminator Posted October 4, 2010 Share Posted October 4, 2010 Personally I think there is a lot of hype around certain fashionable automotive batteries, especial if they get deep cycled, the materials use in them are just not to to the job. I have a 28AH battery, that is probably 1/10 to 1/20 of the capacity of popular full size batteries used in the MKIV. It sits with an alarm on for up to three weeks without use and then will give powerful multiple starts if required. My car had not been started for two weeks before going to Pod yesterday I had problems starting the car and must have pulled on the starter for seven or eight separate attempts to start. Not once did the battery feel like it was beginning to weaken. At this time of year when demands on the battery increase, it is always a good idea to leave the battery on a float charger, then you can be sure not to deep cycle it.

I only went for red-top for one reason... it's red and fits in my battery cage lol. Heard lots of horror stories about the optima batteries but went with it anyway. I think I'll just paint a stock one next time Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 5, 2010 Share Posted October 5, 2010 i have the same problem, i have no alarm and a toyota battery. leave it just over a week and i have to jump start it. it constantly pisses me off. There is obviously something wrong, have you done any checks such as is the alternator actually charging it enough. How old is your battery ? They don't last forever and if you can't find anything wrong with the car i'd splash out £40 and go get a new o/e one from Toyota Quote Link to comment Share on other sites More sharing options...
Brazil Posted October 7, 2010 Author Share Posted October 7, 2010 Hi gusy, I've checked the altenator and it's working, the problem actually fixed it self for a day but now it's craping out again. I am suspecting that it maybe be a loose wire, my neon lights have latetly started to work 'though it's not something that I would use'. I am going to try to follow the wires and investigate that. Any other suggestions guys, would connecting my diognosis link might help find the problem? Quote Link to comment Share on other sites More sharing options...
Dnk Posted October 8, 2010 Share Posted October 8, 2010 I'd be disconnecting the neons and see how it goes. Quote Link to comment Share on other sites More sharing options...
