Nokta Makro Simplex Battery & Charging
The Nokta Makro Simplex battery is a built-in rechargeable lithium pack that charges over USB - there are no disposable cells to buy. Owners generally report trouble-free life over years of use. Here is how charging works, what to expect from runtime, and how to handle the rare charging problem.
The battery and how it charges
The Simplex uses an internal rechargeable lithium battery that you top up through a USB cable - the same USB connection used for firmware updates. One owner summed up the appeal of the whole package: the Simplex "has more features, waterproof, iron audio, a flashlight, rechargeable battery, far more rugged" than cheaper rivals at a similar price. Because it is sealed and waterproof, there is no battery door to flood.
Real-world battery life
In practice, owners find the battery lasts a full day of hunting and holds up over the long term. On a forum thread about Nokta battery concerns, one user said they had "only used my Simplex for a year and a half but the battery was never a problem," and another reported five years with "no battery issues." One caveat worth knowing: some users note the rechargeable lithium cell runs at a lower voltage than a typical alkaline, which is normal for this type of pack and does not indicate a fault.
Charging problems and fixes
- Not charging: try a different USB cable and a known-good power source first - the cable is the most common culprit.
- Short runtime after years of use: lithium packs lose capacity over time; if a long-used unit no longer lasts a session, the battery may be aging.
- Charging in the cold: very low temperatures slow lithium charging; charge indoors at room temperature.
Keep a spare USB charging cable in your kit so a bad lead never ends a hunt. For the full add-on picture, see Simplex accessories, and keep firmware current via Simplex firmware updates.
