Complete guide: EnGen Spare Battery Pack – Set of 2 Batteries
A set of two replacement batteries for the Cheyenne Engen external power unit, designed for artists who work wirelessly and can't afford forced breaks in the middle of a session. The idea is simple: while you work on one battery, the other charges, so you switch from one to the other with no downtime. It's an 'insurance' purchase — it doesn't change how you work, but it guarantees you can work continuously all day.
How to use
- Fully charge both batteries before your first work day, using the Engen system charger (not included in this set — it typically comes with the base unit or is purchased separately).
- Insert one battery into the dedicated compartment of the Engen unit and push it until it locks firmly — the connection must be secure before you turn on the machine.
- Put the second battery on charge, so it's ready when the first one runs out.
- Connect the Engen unit to your compatible machine and check operation at your usual settings before starting on a client.
- When the battery in the unit is nearing discharge, remove it and replace it with the charged one — the swap is quick and tool-free.
- Immediately put the discharged battery on charge, so the rotation continues throughout the workday.
- At the end of the day, store the batteries partially charged, in a cool, dry place at room temperature.
Tips from us
- Alternate the two batteries systematically (don't always use the same one) so the wear from charge cycles is evenly distributed and both age at the same rate.
- Avoid full discharge to zero — rechargeable batteries retain capacity longer if you charge them before they're completely drained.
- Discreetly mark the batteries ('1' and '2') so you always know which one is freshly charged and which is next for the charger.
- Don't leave batteries in the car or in the sun, near heat sources, or in extreme cold — extreme temperatures are the main factor in cell degradation.
- Stick to the recommended batteries for the Engen system; generic ones may not deliver the expected performance and could affect the unit's operation.
- Before each session, visually check the battery: if you notice a swollen casing, cracks, or damaged contacts, take it out of use.
Frequently asked questions
Which tattoo machines do these batteries work with?▾
The batteries do not connect directly to the machine — they power the external Engen unit, which in turn powers the machine. So the right question is whether your machine works with the Engen system: the system is designed to turn compatible machines (pen and rotary) into wireless setups. If you already use an Engen unit, this set is the correct replacement battery; if not, first check the compatibility of the Engen unit with your machine.
Does the set include a charger?▾
No — the set contains only the two replacement batteries. The charger typically comes with the initial Engen unit package or is purchased separately. If you're new to the Engen system, get the base unit first, then expand with additional batteries.
How long does a battery last in a tattoo session?▾
Battery life depends on the voltage you work at, the type of machine, and how continuously you tattoo — long lines at high power drain faster than intermittent shading. Under standard conditions, one battery is sized to support a full session. That's exactly why this set is meant for alternating: one in use, one charging, so you never rely on a single battery life estimate.
How do I maintain and sanitize the batteries in the studio?▾
Treat the power unit like any non-sterilizable equipment in the work area: use a disposable barrier over the unit during the session, changed for each client, plus wipe surfaces with disinfectant between sessions — no immersion in liquids and no disinfectant on the contacts. For actual battery maintenance: avoid full discharge, keep them away from extreme temperatures, and store them partially charged when not used for longer periods.
After how long should the batteries be replaced?▾
Like any rechargeable batteries, capacity gradually decreases after hundreds of charge cycles — there's no fixed expiration date. Practical signs it's time to replace: noticeably shorter battery life than at the start, or a battery that drains quickly on its own in storage. Proper maintenance (no full discharges, no excessive heat) significantly delays this moment.
Can I use cheaper generic batteries in the Engen unit?▾
It's not recommended. Generic batteries may not provide the stable discharge the machine needs for consistent performance and could affect the unit's operation. With equipment you use on skin, stable power isn't a detail — use the recommended batteries for the system, and this set exists exactly for that.
