The search coil, remote control and headphones are all powered by identical lithium polymer batteries. These miniatures, high-capacity batteries can be recharged quickly.
The power adaptor supplied, enables all three elements to be charged simultaneously when used with the USB/3 mini-B cable, also supplied.
Our retailers will offer numerous optional charging accessories, including a charger that plugs into a car cigarette lighter. There is also a miniature field charger powered by just a single 1.5 volt AA battery, which enables the detector to be partially charged (40 to 60%) in just 25 to 40 minutes—very practical!
DEUS constantly informs you of the batteries' charge level:
The remote control alternately displays the coil symbol which indicates the coil's charge level and the battery symbol which indicates its own charge level.
If you decide to detect only with the headphones without the remote control, you will also need to know the coil's charge level. When the coil symbol is displayed, the headphones indicate the coil's charge level on its screen, whereas when the coil symbol is not displayed the headphones indicate their own charge level.
- Coil: 90 minutes
- Remote control and headphones: 120 minutes
- LiPo batteries (Lithium polymer) do not suffer from the ‘memory effect' so you can recharge them at any time without first having to wait for them to fully discharge.
- The pictograms on the headphones and the remote control indicate when charging is underway symbol.
- The LED on the coil is on continually when charging is underway, when charging is complete, the LED reverts to flashing intermittently
The LiPo batteries are designed to bear hundreds of charges and to last several years in your detector, thus resulting in significant savings in terms of purchase of batteries. After 400 charging cycles the battery still has 80% of its capacity, which then gradually begins to decrease over subsequent cycles. As an indication, the batteries should last for around 3 to 5 years when used on a weekly basis.
Attention: long-term storage of discharged batteries may reduce their overall durability. Do not store your device for long periods with discharged batteries! If the detector has to be placed in storage, first charge the batteries to half of their capacity (40 to 70%), which corresponds to approximately two bars on the charging icon. Ideally you should then discharge/recharge them at least once a month.
The three DEUS batteries are identical. The batteries for the wireless headphones and the remote control are easy to replace as they are connected to the circuit with a mini-connector and double-sided adhesive tape. The search coil battery is sealed for obvious reasons of safety and impermeability. It must be returned to our service department or to your local XP distributor for replacement. The batteries, like the rest of the detector, have a two-year guarantee for parts and labor!
The XP emergency charger can only recharge one element at a time. You are advised to keep this reserve recharging system mainly for recharging the coil, which has a shorter battery life than the remote control or the headphones.
In only 30 minutes, and using just a single 1.5 volt standard alkaline AA battery, the backup charger will charge the equivalent of 3 hours of coil operation, or 6 hours of remote control/headphones operation.
If you are in a hurry, you can recharge the detector for only 15 minutes, which will give you an additional 1 to 2 hours of detecting time.The 1.5 volt AA battery can only be used once, as it becomes depleted very quickly in the first 30 minutes of charging, before slowly completing the charging over a further 1 to 2 hours. Ultimately it will only recharge your coil (or remote control) partially, by about 60%, which is normally enough to complete a full day of detecting.
The coil's charging contacts are flush with the upper side of the coil, they have no rough edges and can be cleaned simply by wiping them with your finger. The charging clamp connects easily, due to the raised guides on the coil cover; these are robust enough to accept the clamp even when dirty. Even without the coil cover (and its guides) you can connect the clamp by manually aligning the charging contacts.
The charging contacts are then shielded internally by a protection circuit. In simple terms, the current can go in but cannot come out again. So there is no risk of short circuit when in contact with water or metal. Nevertheless, you should never tamper with the power supply or try to charge the detector with anything other than the XP charger, as this is very dangerous and could lead to fire or explosion.
Despite the battery's small size, the power of the coil is at least as great as the Gold Maxx Power, for instance. It is difficult to explain in just a few lines as it involved a great deal of research. We optimized the efficiency of various elements such as the coils and the amplification stages. There was also the choice of a high-capacity lithium battery and leading-edge electronic components that were more expensive and precise than those usually found in metal detectors. These highly efficient circuits waste far less power: It would be similar to comparing the normal household incandescent light bulbs which are very inefficient, losing 80% of their energy as heat, to those of LED lighting, which uses all of their energy for light rather than heat!
- Wireless headphones: 27 Hours
- Remote control: 27 Hours
- Search Coil: 15 Hours on average (model from June 2010, 9 Hours before June 2010)
The search coil's battery life may vary depending on the modes used. The table below shows battery life according to frequency and power selected.
Frequency 18kHz power at 1 = 20H
Frequency 18kHz power at 2 = 14H
Frequency 18kHz power at 3 = 11H
Frequency 12kHz power at 1 = 19H
Frequency 12kHz power at 2 = 13H
Frequency 12kHz power at 3 = 11H
Frequency 8kHz power at 1 = 19H
Frequency 8kHz power at 2 = 13H
Frequency 8kHz power at 3 = 11H
Frequency 4kHz (fixed power) = 11H
DEUS is regulated in such a way that avoids any deterioration in performance even when the battery level is lower!
