Battery OPTIMA or Energizer

Now I stick to Energizer Max batteries, they claim a 10 year shelf life, and I have some that are 5 years old that are still near 100% state of charge, with no leaks.

I've been running a red top Optima for about four years now and no complaints.

I had an Energizer battery last 13 years in my ranger. Problem was when it came time to change it I couldn't find them anywhere.

Bought my Energizer back in 2013, haven’t let me down once :)

I know some people love to shit on Optima but my yellow top is still kickin at 10 years old. Been run to the ground a couple of times over the years and the slow charger brings it right back.

I run yellowtops in my car and truck and the truck is going on 5 years now and still kicking.

The yellow top is what I have in my car and there is one issue I have with it, the amp hour rating. The yellow top is only 38a/h where the OEM is about 45a/h. This will lead to the inverter using a lot of energy charging the 12v battery and decrease fuel efficiency.

Have two red tops in my 05 GMC. Sneaky suspicion one is bad. They were new when I got the truck six years ago.

Went to start truck after sitting five days and it was dead. Meter showed 12.1 and it charged in an hour which is very fast. Truck would turn over but not run. Checked charge again, primary at 12.4 and secondary at 12.7. Swapped places and truck starts, runs, all accessories work now.

Stay away from optima batteries unless your car specifies an AGM battery because they can be very problematic.

my 2009 had an optima and it only lasted 2 years
