I’m a newbie with a 2004 E4. Sorry, I haven’t found via Search feature answer to my question.
What’s the best maintenance free batteries that’s commonly available at a local store for an E4? Not interested in LiON. My GEM has an upgraded charger. I don’t know brand or anything as I haven’t dug into yet. Just got the car locally.
if your looking for the best lead battery , get a set of 31 gel batteries . Agel battery will significantly out perform any other type of lead battery available . Thats why
Gem put them in your car to begin with . What upgraded charger do you have ? can it handle a gel battery ?
