Charging Time on the Garmin Portable Kits

Garmin makes two sizes of portable bundles. The small kit comes with a 7Ah battery, where the large kit comes with a 12Ah battery. A list of what portable bundle and which battery the kit contains is below. With the current charger, the 7Ah battery takes about 8 hours to charge, and the 12Ah battery takes about 14 hours. Charging varies with temperature, taking a long time to charge at colder temperatures. The battery not fully drained will take less time to recharge.
The lead-acid batteries charged more often and not depleted all the way will help maintain the battery's life. Do not use or attempt to use rechargeable batteries intended for cordless power tools with Garmin products.
