Need to replace both batteries in Benz E320 2003

Inspect Battery Performance: An old battery can cause variety of electrical problems, including one that won't turn over.

Hence, the most important thing to do is to check the charge and age of the current Mercedes-Benz batteries. Usually, a good battery can last over a decade. However, even the best batteries should be replaced every 6-7 years to avoid any hassle.

Low charge is a major headache for many car owners. If you hear just a few clicks before it stops, then you can easily resolve the issue by just trickle charging your battery with a 12-volt battery charge.

need new batteries - how old are the batteries in there now?

If you don't know how to change the oil, let a garage do it, there are no instructions in the owners manual for changing the oil, (drain the oil from the oil pan, remove the oil filter and replace with a new one, depending on your climate, use 5w-30w or 10w-40w and don't buy the cheapest oil filter, you have a Benz.

Just call a couple parts stores and get prices, the cheapest battery is rarely the best deal and they can dispose of the old one for you. They will know what size you need. Also if you have a warranty need in the future they are open seven days a week.

if your car left hand drive please forward front passenger seat if your car right hand drive need to forward driver seat, then fully fold backrest to forward then you can see under the seat carpet have been cut by 3 side you have to fold that carpet to front, after that you can see the battery in it in this particular model very hard to replace battery and also risky some time need to remove seat, in your car have two batteries both sitting in under the seat and also, need to be check both batteries, you may need to get experience technicians hand to do that, some impotent control units and fuse boxes has fixed close to battery, when you going to replace the battery if get some thing wrong you may have to be loose lots of money if you do it by experience technician it's only jest one our job I would like to advise you to get it in to Mercedes dealer to do it after replace battery it's need to be check charging rate and normalize many electronic component and erase all fault codes this is the best way it's up to you. is this information helped you? please leave a comment.

If you can get under the car and use jumper cables at the starter you can put power to the system to get car open. There are better ways but this is the cheapest way without other help. That and its free.

It's not that unusual for a battery to fail that soon, and the "no lights, no nothing" says that it's the battery again. Your best bet at this point is to pull the battery and take it to the point of purchase for testing. They should either replace it under warranty or charge it for you. After you replace the battery you should have the charging/electrical system checked for possible shorts or power drains.

thats a good price, a mercedes battery alone is over $ 100.00 that a good one. saers and autozone are usauly the cheapest, and you dont need a part # all you need is year, make and model of car to get any battery, good luck.

The cheapest battery isent the best to get as the one which sells a lot is good and the ALTERNATOR must charge at 13.5 amps and battery 12volts.
Turn on head lights and start engine if lights brighten up then its charging But if the lights dont go bright then the alternator isent up to standard so get it reconed So check charging before buying a battery. Let me know how you go with it Ron
