Insert this 15.6Ah lithium battery into a compatible Brass Monkey Fridge/Freezer and power it independently from a vehicle. Lightweight, yet powerful, it simply snaps into a dedicated internal battery cradle.
Taking a fridge on a picnic, fishing on a riverbank, keeping a fridge in easy reach on a work site or running a fridge for extended periods where vehicle power is not available, is a great reason to add a dedicated lithium battery to a compatible Brass Monkey Fridge/Freezer. The battery fits into a dedicated battery cradle installed in the fridge and then it is ready for independent operation.

Picking the right battery size
There are 3 battery sizes available, 5.2AH, 7.8AH and 15.6AH. To get an idea of which battery size is the most suitable choice for any fridge:
Example calculation:
1. Fridge amps = 5 amps,
2.Working on site for 8 hours independent use,
3. Fridge in covered area and opened for meal and drink breaks - say running 30%/hour.
Battery size in AH = 5 Amps x (8 hours x 30%) = 5 Amps x 2.4 hours = 12AH.
Closest size up is the 15.6AH battery
Note: This is a very rough means of estimating a suitable battery size. Fridge running time will vary depending on daily ambient temperature, the fridge set temperature, where the fridge is located, and the volume of food stored versus air space (a full fridge has less air to lose when opened). Weather and use conditions will vary on any given day, so estimate the battery size using the heaviest likely use, to find the most suitable battery size. If in doubt, buy a bigger battery and/or consider a supplemental charging system (below).
