Frequently Asked Questions
Q: Which TACTACAM cameras does this Defend battery work with?
A: This Defend battery works with TACTACAM Reveal X, Reveal X Pro, Reveal XB, Reveal SK, Solo, and Solo X cellular trail and security cameras. It replaces the original TACTACAM battery pack directly.
Q: How long does the Defend battery last in a TACTACAM camera?
A: With a full charge, the Defend battery powers a TACTACAM camera for several weeks to months, depending on how often the camera triggers, signal strength, and temperature. In typical cellular upload mode with daily activity, you can expect weeks of runtime before recharging.
Q: Is this an original TACTACAM battery?
A: No. This is a Defend-brand replacement battery built for TACTACAM cameras. It matches the fit and power needs of the original TACTACAM battery. It is not made by or linked to TACTACAM.
Q: Can I use this battery in cold weather?
A: Yes. The Defend battery works in a wide range of outdoor temperatures. For best results in extreme cold (below -4F/-20C), keep a spare battery indoors and swap as needed. Cold weather shortens all lithium-ion battery runtime.
Q: How many times can I recharge this battery?
A: The Defend battery lasts 500+ full charge cycles while keeping at least 80% of its original capacity. With normal use, it will serve you for 2 years or more before you notice any drop in runtime.
Q: What is the difference between Defend EM10 and EM9?
A: The EM10 has a higher capacity and runs longer per charge. It is the best choice for cameras in remote or high-traffic locations where you cannot swap batteries often. The EM9 has a standard capacity and costs less. It is ideal for cameras you can access and recharge more frequently. Both models fit the same TACTACAM cameras.
Q: Which TACTACAM cameras does this battery NOT work with?
A: This battery does not work with older TACTACAM models that use AA batteries, such as the original TACTACAM Reveal (non-X) that runs on 12 AA cells. Always check your camera manual to confirm it uses a rechargeable lithium-ion battery pack.

🔋 Lithium-Ion Battery Conditioning
For optimal electrochemical performance, new lithium-ion batteries should undergo 2–3 complete charge and discharge cycles before reaching full capacity.
This stabilization phase allows the internal cell chemistry to achieve balanced ion distribution, ensuring maximum runtime, stable voltage output, and extended cycle life.
After this initial conditioning period, no further full discharge cycles are required.
