Besides a killer battery, I need to know if it is a gellcell(what I thought it is) or lead acid.... I know it is a deep cycle. Why I need to know this is we may need a heat blanket for it as "other batteries" lose 50% of their power when it get -blue balls outside(Whitehorse!). The Optima website only compares it to other lead acid.....Thanks for any help!!![cheers]

An Optima battery is a gel cell battery that has the plates spiral wound instead of flat plates and the Red top is NOT a deep cycle the Red top is the high amperage starter battery the Yellow top is the deep cycle/RV battery and the Blue top is the marine version

I bought the red last year at Walmart for $139.00 so it will be o.k. up here. I bought it for my Toy with the 8274, but it ended up in the Nissan!! Thanks guys!! So I guess no heat blanket......

on the bottom left in says glass mat to avoid acid spilling....? It sounding like an lead/acid, which means 50%less power in cold weather(-30-40). I need to figure if I NEED A BATTERY BLANKET!!!!

"These are the batteries that we used on the Warn Glacier Expedition in Iceland. They performed beautifully and seemed completely unaffected by the cold. They worked for hours at a time as we winched the Jeep up and down Hvannadalshnjukur mountain and across Vatnajokull glacier. We also encountered very steep grades, but experienced no leakage with these starved electrolyte batteries."

Thier site says otherwise...... I e-mailed them to find the straight goods as I always thought they were gell cell too. They keep flappin bout lead acid though......so what about the cold temp it will see?? would you guys get a heat blanket for it?

they are an absorbed matt lead acid battery meaning they have no free acid floating around like a typical lead acid battery but instead a cloth like material spiral wound with the lead cells holding the acid in place

get the yellow top because once the battary is dead you can re charge it..but the red top you cant do that!!

Bought the red top LAST YEAR, killed it and it recharged fine, and yes it needs a heat blanket for cold climates!!!

he mean's the yellow is a deep cycle made to be completelty drained and recharged ... the red top is made to be a starter batt and to allways stay above 50 % for best life span ....

They are not a gel cell battery. They use a mat instead of gel. Much cheaper and they can use the same electrolyte as a normal battery and the same heavy metal.

Not to stir things up, but I came across this on ultimateyota.

It's worth the read.
