Actually, the Camry Hybrid and the Prius 12V batteries are not the same.
The Camry Hybrid 12V battery is larger, higher capacity, and more
expensive. The batteries are both AGM (Absorbed glass mat) deep cycle
batteries, just as the original Panasonic batteries are.
The aftermarket battery for the second generation Prius is the Optima
model DS46B24R (D51), part number 8171-767. $170 from
<
http://www.elearnaid.com/opdsopbadifi.html>. While it will work in a
Camry, it's much lower capacity than the original battery (38AH versus
57AH). That capacity matters in a hybrid where accessories run off the
12V deep cycle AGM battery when the gasoline engine isn't running.
You really want to use the D35 (8040-218) or D75/25 (8042-218) battery
in the Camry Hybrid which are 48AH. Still less than the 57AH for the
OEM, but not as far off as the Prius battery. The D75/25 has the
terminals in the proper position, the D35 has them reversed but you can
just install the battery backwards. The problem is that neither of these
batteries have the vent hole for the vent tube, only the 8171-767 (D51)
has the vent hose connection.
The bottom line is that for the Camry Hybrid you're left with three
choices: 1) the original Panasonic battery (a custom battery sold only
by Toyota) 2) a much lower capacity Prius battery, or 3) a slightly
lower capacity Optima battery that is not properly vented. #3 is why
elearnaid states "If you are looking for a battery for a Camry hybrid.
Click here for what we recommend. Fits well and includes Toyota vent
tube connection hole." Then they refer you to the Prius battery.
