OEM Battery Replacement
My car failed to crank this morning, dash lighted up and headlights flashed as i turned key, did a quick google search on my fone and found out it was my battery, then called CAA for a boost.
I thought the recent cold weather had something to do with it, When i got home had a look at the battery and found the "eye" to be black - or could be green - the battery seems rather old.
From the top i couldnt really see any indication of date, only visible date is recharge by date 3-09? Not sure what that means, how can i tell how old the battery is? Seems like the original battery.
im thinking of replacing the battery anyway and would just like some help on which ones to get? Also should all the specs be identical? Or can i go higher without affecting the electronics but also robust in winter?
I just want a battery that will be solid during winter. From e46wiki:
"49DL" and "94R" are standardized battery sizes that will have specific height, width, and length dimensions. So i guess i need a 94R?
What are some good cost effective replacement brands?
How is the exide brand from part source?
Also is there an accurate way of reading battery voltage thru diagnostics? I dont have a multimeter? What should the readings be?
