Lightweight battery kit or battery relocated to boot?

[Rock_Evo]

Hello, I am new to the forum and new to owning an evo in general. I have recently bought a 2001 evo 7 it has been running fine. I was out in it last week and then I came home, 20 minutes later I went to go back out but the car seemed to die all of a sudden as soon as I turned the key and it didn't even try to start! The lights were dim and flickering as if the battery was very low. I jump started the car and left it running, as soon as I turned the lights on the engine cut out and wouldn't start again. I think maybe there is a loose ground cable as I've never known a battery to die so quickly! while looking for a loose connection I noticed the car has had a new alternator fitted so previous owner could maybe have been trying to fix the same problem? Has anyone had this problem? Also the battery that is in the car is not full size but is smaller and is just clamped down to the stock tray to make room for the top pipe, it looks scruffy! I want to tidy it up but not sure wether to get a mini battery and tray kit or to relocate a full size battery to the boot. Are the mini batteries adequate for daily driving and our uk winters? if so does anyone know of any kits available in UK? Any help will appreciated, thanks.

Hi, you need to do basic checks first,
1. Test battery with volt meter, expect 12.6 volt with engine off, then up to 14.6 volts when running.
If you don’t get up to 14.6 plus volts you need to check the alternator.
2. To do this you will need an amp meter to check the alternator is charging ok.

the Evo is not the same as ordinary cars of this age, it controls charging via the ECU, when you ask the engine for high power the ecu will turn off the alternator, so let’s hope it’s a simple fix.

I should recommend you sort out the problem before you start relocating it

good luck
