Battery replacement on 997S

Looks like my battery is done. OEM replacement is lead acid. Canadian Tire has AGM at 1/3 less.

Also, any special precautions to be aware of? Appreciate any suggestions. Thanks.

Watch for the size of the battery, both for the hold down brackets, and the length of the cables.

I picked up one from Canadian tire.

Ultra agm size L4/94R is an exact fit.

You can go a size down if your battery tray has the extra tie down holes.

Just check to make sure it comes with the vent tube & black plastic tube end.

I noticed some batteries on the shelf were missing those extra items.

Thanks for the info guys. Called dealer and he doesn't recommend AGM for this model year. He says the charging system may not be compatible with AGM!

i have ran an agm in my 944 and 914 for the last 4 years and had no problem with the charging system. when the battery dies in my 997 i will put one in. it is still a 12 volt battery just different technology.
