What battery does the SkyWand use?
A rechargeable 3.7 V 3000 mAh Li-ion pack, and only that pack, per the manual. Every kit includes two.
What do the charger lights mean?
Red means the pack is charging; green means it is fully charged. A full charge takes approximately 4 hours.
Do I need to charge before first use?
Yes, the manual states the Li-ion battery must be fully charged before the first use. Wait for the charger's green light before loading the pack.
How do I charge the battery packs?
Seat the pack so its anode contacts the charger's anode and its cathode contacts the charger's cathode, then plug the charger into wall power. Red means charging, green means full, about 4 hours.
Can the battery charge inside the wand?
No, there is no in-lamp charging documented. Remove the pack and charge it in the included charger; that is also what makes the two-pack swap workflow possible.
Can I use a third-party charger?
No. The manual's caution is to use only the charger packed with the lamp, other manufacturers' parts can affect performance and will void the warranty.
Can the charger recharge other devices' cells?
No, the manual specifically says not to use this charger to recharge any other products. It is dedicated to the SkyWand's 3.7 V 3000 mAh Li-ion packs.
Are spare batteries available?
Yes, we supply original 3.7 V 3000 mAh Li-ion packs as accessories; request pricing through our quote page.
Stick to original packs, other manufacturers' batteries can affect performance and void the warranty.
How many charge cycles do the packs last?
300–500 charge/discharge cycles or more, provided the pack is not overcharged or heavily discharged, per the manual.
Does UV output drop as the battery drains?
No. The lamp maintains constant UV output, the power will not fade, even on a low battery, so every cure gets the same dose.
What happens when the battery runs out?
Output stays at full strength until the pack is empty, then the light simply stops rather than fading gradually. Swap in the charged spare and put the empty one on the charger.
Is deep discharging the packs bad?
Yes, the manual warns not to subject the batteries to repeated deep discharges that run them down completely on a regular basis, as this greatly shortens battery life.
Swapping to the spare pack promptly and recharging keeps you inside the 300–500-plus cycle life expectancy.
Should I worry about overcharging?
The manual's stated cycle life of 300–500 cycles or more assumes the pack is not overcharged or heavily discharged. The charger shows green at full charge, taking the pack off once it is green is the simple way to avoid overcharge.
Which way does the battery go in the charger?
Anode to the charger's anode, cathode to the charger's cathode, the manual illustrates the contacts. Once seated, plug the charger into wall power and look for the red light.
Which way does the battery go in the lamp?
Anode (+) forward toward the head, cathode (-) at the tail, per Step 1 in the manual. A reversed pack is the first thing to check if the lamp will not switch on.
Do the packs contain lead or mercury?
No, the manual notes the Li-ion packs have no toxic lead or mercury.
They still must be recycled per local disposal laws rather than binned, and never disposed of in fire.
How do I dispose of worn-out packs?
Recycle them according to your local disposal laws. Never dispose of Li-ion packs in fire, the manual warns they will explode.
Can I fly with the SkyWand kit?
The manual does not cover transport rules, so check your carrier's and local regulations for lithium-ion batteries before flying, the kit carries two 3.7 V 3000 mAh Li-ion packs.
How should I store batteries long term?
The manual does not give a storage charge level; what it warns against is deep discharge and overcharge, so do not store packs dead flat or leave them on the charger indefinitely. Keep them with the kit in the carry case.
Do temperature extremes affect the packs?
The documentation does not publish temperature limits for the packs. As a general rule keep the kit in its case away from extremes, and ask us if your storage or work environment is unusual.
When should I replace a battery pack?
When runtime drops noticeably, packs are rated for 300–500 charge cycles or more with good charging habits. Replacement original packs are available from us.
Can it run corded from wall power?
No, the SkyWand is battery-only, with no documented corded mode. The charger charges packs outside the lamp; the two-pack rotation is how you get continuous uptime.
What's the charger's input power?
The manual simply says to attach the charger plug to the main power source and does not publish input ratings. If you need electrical details for your facility, contact us and we'll get them from Uvitron.
Can I top off a partly drained pack?
Nothing in the manual prohibits partial-charge top-offs, its warning is against the opposite habit, repeated full run-downs. Topping off keeps you clear of deep discharges.
How do I know the pack is fully charged?
The charger's indicator light turns green when the battery is fully charged; expect roughly 4 hours from empty.
How do I know charging has started?
The charger's indicator light shows red when a pack is on charge. If you do not see red, re-seat the pack and check the anode/cathode orientation and the wall connection.
Can the charger hold two packs at once?
The manual's charging illustrations show two packs seated in the charger side by side, each with its own indicator.
In day-to-day use you will usually have one pack in the wand and one on charge.
How many cures do I get per charge?
That depends on your exposure time, a pack delivers roughly 2 hours of total on-time. Short spot cures of a few seconds each add up to a large number of cures per charge.
Why has my runtime gotten shorter?
Packs age with use, 300–500 charge cycles is the documented life expectancy, and repeated deep discharges accelerate the decline. A fresh original pack restores full runtime.
Can I use batteries from another brand?
No, use only the specified 3.7 V 3000 mAh Li-ion pack supplied as an original accessory. The manual warns other manufacturers' parts can affect performance and will void the warranty.
Does the wand show battery level?
No charge gauge on the lamp is documented, the only documented indicators are the red and green lights on the charger. Keeping the spare pack charged is the practical safeguard.
How do I swap packs mid-shift?
Switch the lamp off, unscrew the tail cap, swap in the charged pack anode-forward, and re-fit the cap. Put the drained pack straight on the charger so it is green before you need it again.
Is overnight charging OK?
A full charge takes about 4 hours, and the documented cycle life assumes packs are not overcharged. The conservative habit is to charge during the workday and take packs off once the light turns green.
Does the kit include a charger cord?
Yes, the charger ships ready to plug into wall power, and the kit photos in the manual and brochure show the charger with its power cord in the case.
Can I run two packs in the lamp at once?
No, the lamp takes a single pack (power supply: one rechargeable Li-ion battery). The second pack's job is to be charged and waiting.
Will new packs arrive charged?
Treat them as needing a charge, the manual requires the battery to be fully charged before its first use. Give each new pack a full charge to the green light before loading it.
Why does constant output matter?
Because the dose is the same at full charge and low charge, you never have to re-validate exposure times as the battery drains, every cure gets the same intensity.
Where do I get a replacement charger?
From us, it must be the original Uvitron charger, since the manual voids the warranty on other manufacturers' replacement parts. Request one through the quote page.
What chemistry are the batteries?
Rechargeable lithium-ion (Li-ion), 3.7 V 3000 mAh, with no toxic lead or mercury per the manual.
Does the battery add much weight?
The published weight of 130 g already includes the battery, so the wand stays light in the hand fully loaded.
Do unused packs self-drain in storage?
Self-discharge is not specified in the documentation. The safe habit is to charge a pack before a job rather than assuming it held its level, and never to store packs completely run down.
What's the safest way to handle Li-ion packs?
Use only the included charger, avoid repeated deep discharges and overcharging, recycle worn packs per local law, and never dispose of them in fire, the manual warns they will explode.
