There are some batteries that allow for deep cycling, which from my understanding means you can run through a sequence of charging and discharging to return the battery to original state.

Then there's the option of going with a light weight battery for weight saving because race car. However, those tend to have a smaller capacity (less material, different material? I don't know) and require frequent driving to keep the battery running.

In the end I went with a Kirkland battery from costco. From what I read, the supplier for the Kirkland brand is actually a really well known battery manufacturer that also produces the AGM Exide batteries. Don't quote me on that. Brand name or not, the warranty was too good to pass up on. For $105+tax vs oem honda $170+tax, the costco battery has a free replacement for the first 3 years, then each year after the initial 3 years has a reduced % of refund.

Edit: lesson learned - start up car occasionally to keep battery alive or use a trickle charger.


Starting a car occasionally during storage does not help. As each time you start the car it drains the battery then leaving idling for a period won't allow enough charge therefore it's best that the battery is connected to a trickle charger as this will keep the battery in a healthy condition.
