51 battery replacement

Have replaced OEM type 51 battery 3 times in 10 years in our ’08 CRV. #4 starting to go bad. Read about upgrading to a larger capacity battery. After reading different threads in this forum, bought a Duracell 35/85 AGM @ local Sam’s Club. Type 35 battery is slightly smaller than the type 24R...

Normal parasitic drain is fairly low on 2007s, so rather than upsize the battery, I would suggest a 51R with the higher 500 CCA rating. You pay a bit more for them compared to the older 410 CCA 51Rs, but you also get more reserve charge.
