What Batteries should You Use for Your Smart Digital Locks?

Digital locks, like any other electronic devices, need batteries to function well. Here's a question we receive on a daily basis: What kind of batteries should I be using for my igloohome digital lock?

Tips on changing batteries for your digital locks

1. Always use alkaline batteries.
   

2. Change batteries every 8 - 10 months. Not recommended to mix the old with new batteries.

3. Diligently check for battery leakage every 6 months.

4. Avoid lithium, carbon-zinc and rechargeable batteries altogether.
   *Smart Padlock is the only exception that uses lithium batteries.

All igloohome digital door locks come with a pack of batteries, however, these are used for testing purposes after the installation is complete. We always recommend for you to change them out once the testing is done.

Recommended Batteries

For optimum results, we only recommend alkaline batteries. These types of batteries work best with our locks and can typically last up to 12 months depending on the frequency of your usage.

The brands to get are Energizer, Duracell and Panasonic. As a rule of thumb, batteries should be changed every 8 - 10 months to to prevent battery liquid leaks. We do not advise for you to leave batteries in the lock for more than a year as the battery cell expands towards the end of its lifecycle due to chemical changes. This could lead to higher risks of battery liquid leaks in that period.

Avoid lithium and carbon-zinc batteries as these run out of power much faster than alkaline ones. Neither should you use rechargeable batteries as the power is lessened with each recharge.

Take a look at this chart for our recommended battery list:

	Product Name	Battery Type	Battery Brand(s)	Photos
IGP	Smart Padlock 1	CR2 Lithium	Energizer / Duracell / Panasonic
IGK	Keybox 3	AAA Alkaline	Energizer / Duracell / Panasonic
IGM	Mortise 2	AA Alkaline	Energizer / Duracell / Panasonic
	Mortise 2+	AA Alkaline	Energizer / Duracell / Panasonic

IGB	Deadbolt 2S	AA Alkaline	Energizer / Duracell / Panasonic

Other important things to note:

• Please do not use Lithium(only allowed for IGP), heavy duty, rechargable batteries.

• For IGM, IGB, you are recommended to change to another new set of batteries after you have tested the functionality of the lock with those batteries included in the box.

• The CR2 lithium batteries used in the Smart Padlock works between -20 to 60 degrees celsius.

• The LR03 AAA alkaline batteries used in the other locks work between -20 to 54 degrees celsius.

How if the lock's battery power is completely out?

In this case, use a 9V battery to jumpstart the lock.

1. Touch and hold the battery contacts against the 9V jumpstart pin on the lock and you will hear a series of beeps and the keypad will light up if the batteries are fully drained.

2. While holding the 9V battery to the jumpstart, key in your PIN code on the keypad followed by the ‘Unlock’ icon

Note: Please ensure the terminals of the 9V battery are in proper contact with the contact points on the lock.
