Battery FAQ (S720, D720, D800)

Minimum first charge time (important)

If the scanner is new or has been sitting, fully charge it before first use. Many “won’t power on / dies quickly” first-day issues are caused by an incomplete initial charge.

• S720: ~6 hours
• D720: 6 hours
• D800: 8 hours

Battery type and options

• S720: Rechargeable NiMH AA batteries (replaceable). Not lithium.
• D720: Rechargeable Lithium-ion polymer battery pack (replaceable).
• D800: Rechargeable Lithium-ion polymer battery pack (replaceable).

Can I use one-time (disposable) batteries?

• S720: Uses AA form factor batteries, but it is specified for rechargeable NiMH. For best performance (and to match published battery life), use the recommended rechargeable NiMH set.
• D720 / D800: No. These use proprietary rechargeable battery packs, not disposable cells.

Average battery lifespan (typical use)

Batteries are rated for ~500 charge–discharge cycles. As a practical planning estimate:

• ~1 full charge per day: about 16–17 months
• ~2 full charges per day: about 8–9 months

Note: This is the battery lifespan (capacity typically declines gradually). These models use replaceable batteries, so reduced runtime usually means “swap the battery,” not “replace the scanner.”
