Battery Size & Heat Shield

The battery in my 2009 Versa S MT-6 built in Oct/2008 started getting weak so I measured the size of the battery and then researched what battery I should get. The first surprise was that CVT model took a different battery than the model with MT or regular AT. The second surprise was that the length of the original battery was about 8.25 inches and the replacement batteries were about 9.5 inches while width and height were good. I was concerned about the length because the battery heat shield was not stretchable for the longer battery. The end result is the new battery is longer and fits fine in the battery container with the original side clamp. The original heat shield will not wrap around the new longer battery so I installed it with the open side away from the engine.

I was wondering what other members did or did they have a Nissan battery installed? One advantage of the longer battery is the higher capacity.

Installed without the plastic shroud... If they consider that a heat shield, it's a pretty poor excuse for one anyway.

Don't recall the exact model but I got a Super Start Extreme. It had the highest CCA at 600, and fit the space (-ish) a little wide, same as yours, but fit alright.

You are right about the puny heat shield.

Plastic is actually a good heat shield, good heat capacity properties. Especially considering your main source of heat is a radiant source, the water bridge/distributor.

HDPE and PP, the 2 types of plastic that shield might be made of (I could figure it out, but its not worth my time), are terrible heat shields. Some plastics work, but that shield, or cover, is not very good. Doesn't hurt anything to keep it, but you won't hurt the battery in the least by ditching it.

I think we can agree to disagree.
