S55D23R Fitment Note: The DEKA 9A35/85 shares the Group 35 / JIS D23R footprint and sealed AGM construction as the OEM Panasonic N-S55D23R/JH, making it a compatible replacement for Toyota RAV4 Hybrid (2012-2018) and Toyota Camry Hybrid 12V auxiliary battery applications as well as standard Group 35 automotive vehicles. Some hybrid vehicles may briefly display a battery recalibration notice after installation as the charge-control system adjusts to the new unit.

Panasonic S55D23R Cross-Reference

Panasonic Part Number	Description
N-55D23R	Base JIS flooded MF battery, 55Ah. Direct like-for-like in the D23R case. Standard OEM equivalent.
N-65D23R	Upgraded flooded MF, higher capacity. Same D23R footprint, common upgrade path for standard vehicles.
N-S55D23R (CAOS Blue)	Premium AGM equivalent for standard charge-control vehicles. Closest Panasonic match to the DEKA 9A35/85 in non-hybrid applications.
N-S55D23R/JH (Hybrid OEM)	Hybrid VRLA variant. Toyota RAV4 Hybrid OEM (28800-28102) and Camry Hybrid OEM (28800-28100). Same D23R case and sealed AGM chemistry as the DEKA 9A35/85, compatible replacement with 50Ah capacity vs 45Ah OEM.

Toyota OEM Part Numbers: 28800-28102 (RAV4 Hybrid 2012-2018), 28800-28100 (Camry Hybrid). If you are replacing the 12V auxiliary battery in one of these vehicles, the DEKA 9A35/85 fits the D23R tray and matches the sealed AGM chemistry of the OEM Panasonic unit.
