2015 XC60 RD (<39K miles)
Looking back at my older post (Dash Cam and Low Battery Charge) I had the original battery replaced 10/17 (~3.5 years) due to slow crank and dealer diagnosed as bad cell in battery. I did not note down the original battery part #, but the replacement was Volvo 30772221.
Lately I've been seeing battery low messages with the replacement battery. Sometimes it was after operating the power tailgate (e.g. 3-4 cycles) with engine off, but since the car doesn't get enough sustained use (mostly short drives 4-10 miles once or twice a week) I decided to check further. I used a hydrometer to check the individual cells before and after charging (Battery Tender Plus). Battery fluid levels seemed fine, but one cell was one ball low (and remained low even after charging).
Given that the battery is nearing 4 years old (it also has a sticker dated 10/17), should I just start looking for a replacement? Lowest cost for Volvo battery nearby NY/NJ is $225 at a dealer (using the web scheduler for cost), which I imagine will perform a battery reset.
Or go aftermarket (maybe AGM)?
Or can the bad cell issue be reversed with a better charger/conditioner? <= (need one anyway for something else)
On the RDAR update, can that be applied yourself or it has to be done by a dealer? I do use Sirius, and I don't know/need to research if dealer previously applied RDAR update.
