You can confirm this by looking on the bottom of the OEM battery; it has the manufacturer’s name on it.

As for the using a trickle charger, one word: Don’t. Trickle chargers actually speed up the death of healthy batteries, what you want is a battery maintainer, which (unlike a trickle charger) lowers the charge rate and then turns completely off when the battery is fully charged. Maintainers can significantly lengthen battery life as they keep them in optimal condition while the car is not being used.

The dealer put a new Interstate in last year. I was wondering about maintenance. I was going to buy a trickle for winter storage....thanks for the maintainer tip...I will buy one instead!
