check the cells on the battery, remove the cover off the top of the battery and fill up the cells with pure water, see if that solves it, if not then its time for a new battery. hope this helps :-)

Hi Alan Yes you are right the alarm will go off unless the battery is that flat that it doesn't have enough power to sound the alarm. This is the old catch 22 situation. Have a pair of grips and a 10mm spanner ready to minimise noise time. If you have the radio code, you can unlock it with the key, pop the bonnet, and disconnect the Negative lead with the green thumbscrew and pull it off the terminal first to reduce the risk of shorting, also tends not to spark as much as the other way, then when you come to disconnect the Red Positive, theres no way you can short your spanner to the vehicle earth. Ahhh, Silence! then remove the Positive lead and charge your battery, remove the cell plugs to let the hydrogen gas escape, and make sure its well ventilated, otherwise, BANG could happen, unless its a sealed battery, then don't worry. Once its charged reconnect in the opposite order, but be ready with your keyfob, or better still have a mate ready as soon as you hear the alarm, lock then unlock. Then just re-enter the radio code by pressing the respective number buttons. If you don't have the code, you will need it reading, usually about £10 - £20

lead acid (auto) type batteries cannot be left in a discharged state very long without damage ...if they have been discharged awhile then they will recharge but at greatly refuced capacity ... sometimes they can be recovered but usually its perminant damage .. even if the batteries can be saved it would still take several hours to recharge ...so leaving it on a charger overnight will show you if its a lost cause or not ...you can have the batteries "load tested" usuallly at auto parts stores for free .....they should be fully charged first to save time ...lead acid batteries should always be kept in a state of full charge ...never store them in a discharged condition or allow them to selff discharge (a discharged battery will freeze over the winter) ... charging once a month should keep them healthy .. more often in a car since the computer draws current all the time .. if you have a regulated charger then you can leave it connected all the time for storage ...high resistance battery connectios will have the same effect .. so remove and clean the battery terminals to eliminagte that possibility ... you can have your alternator tested at most auto parts stores ..usually free .. if you have maintainable batteries then check the water level . dont over fill .. use distilled water ...if your charging systems are ok then it sounds like you need new batteries ...

Testimonial: "Thnak you. Sounds like I need a new battery after last winter."
I would start by checking for draws. You can do this with a DVOM capable of reading amperage or with a low amp probe. With a volt meter set the meter to the 10 am range. Remove the positive cable from the battery. Hook one lead of the meter to the positive battery post and the other to the positive cable end. You should see less than .050 amps of draw and better yet at least half of that. If you see more you will need to start pulling fuses to see which one makes the draw go away and then focus on that circuit. Btw, always post a Year, make, model, and engine size with any automotive related question. Let me know if you have any questions and I'll do my best to answer them. Thank you for using FixYa.com!
