Honda Odyssey 2002 battery needs to be replaced again!!!?
 

Can someone please tell me why a battery needs to be replaced on a Honda Odyssey Van 2002, this is what Honda mechanics told me today, it has already been replaced once, I always thought the battery lasts forever.

battery's last forever are you kidding me?battery = source to ignite engine etc..battery's dont regenerate especially on a 2002 honda!a battery is just like a remote control battery after consumed needs to be replaced. chemistry basics :Por if you did not start your car in along time you need to replace it or use those kits to start your car again :P

Three to five years would be average. I have a 2003 Element with the original battery....so it could depend on the type of battery that is being installed. I have had batteries go bad in a relative short time for no reason. Could be something else like a weak alternator or something draining your battery.

A battery has a life expectancy of from 2 - 5 years. If you get anything longer than that count yourself luck. You don't give any information about where you live. In the heat like that here in Las Vegas, a 1 - 2 year life expectancy is about average. If you live in Minot, North Dakota the cold can have just as damaging an affect as the heat in Vegas. Also, you mention nothing about accessories. If you have a lot of accessories or add on electrical items and have not checked your alternator or replaced it with a bigger capacity you could be destroying your battery because it is constantly being drawn down. But there is no such thing as a lifetime battery - the automotive industry wouldn't develop on even if it was scientifically possible.

upgrade the regulator in the alternator or next time get a marine battery that has a longer life span.

Whatever you do, don't buy a Redtop brand battery they are total junk. My friend and I both bought that overpriced Redtop battery and they lasted only 1 year each. A 2002 needing a 3 battery, that's certainly possible considering your vehicle is about 6 years old. Most batteries last 3 years on average, so don't feel bad about dropping another $80-100 on a battery. A recent article in Autoweek was talking about how modern cars drain batteries even when not running and can't recharge properly for those driving short trips. Newer cars have some many electronic devices that continue to run in hibernation mode and therefore can kill your battery fast if you are someone who doesn't drive your car every other day at least.
