Just thought I'd add a review since I've noticed that many websites having incorrect recommendations about which batteries will fit in the Highlander since they do not differentiate between the hybrid and non-hybrid versions. (Hybrid = Size Group 51R)
So, the 5 star rating is purely for the fit---I will update this review if the battery does not perform comparably or better than the battery it's replacing--- it's an exact fit for the battery indentation at its base (where battery temp gage can monitor it accurately + keep it from sliding) as well as for the battery cover to slide down over top of it in a 2006 Toyota Highlander Hybrid.
And for anyone else purchasing for this vehicle, here was my reasoning for choosing this particular battery:
So, I was initially hesitant to buy this battery since it had a lower CCA (450) / CA (575) / RC (66) than its previous battery, which was an Autocraft Gold 51R-2 (standard lead-acid flood) battery with CCA 500, CA 625, RC 85 min. However, since the Highlander hybrid's engine is started by the traction battery and not the 12V battery (and therefore not utilizing peak CA draw), it's my presumption that having a deep cycle battery will hold up better in the long run since the '06 HH has a tendency to suck batteries dry in relatively short periods of time (which generates hybrid system fault codes if the 12V runs too low to run the controllers)---and since AGM batteries can accept a charge faster than a standard battery and have a slower self-discharge rate, it might tolerate the constant charging/discharging better over time.
(Side note: the Autocraft battery was already above OEM requirements, so dropping to a lower CA battery should not be a problem in this instance.)
In short: despite a lower peak & average cranking amps, I'm thinking that the YellowTop's more favorable charge/discharge properties (and longer lifespan) may make this a better choice for my vehicle.
***UPDATE, 3 YRS OUT***
Lasted almost exactly 3 years; not holding a charge like it should now, but still useable until the replacement arrives with an occasional booster charge. I think what finally did it in was when the battery had a total discharge when I was gone for around 3.5 months in the winter - didn't seem to hold a charge properly afterward (using an AGM smart charger), though it worked for several weeks. I think the lifespan was acceptable given that it was always outside in the Sacramento-heat / triple-digit summers. I plan to purchase this again.
