Replacement battery and dual USB charger

This kit includes one lithium-ion SLB-10A cell and an LTD2 charger designed for the SeaLife DC2000 underwater camera. The battery delivers 3.7 V and 1400 mAh for 5.18 Wh of capacity. The charger accepts Micro-USB or USB-C input at 5 V and up to 15 W. It is aimed at divers and underwater photographers who need a spare power source and flexible charging.

Sustained charging behaviour with dual-bay operation

The charger powers two batteries simultaneously at 800 mA each, maintaining that rate across both bays. When only one cell is inserted, the single output also runs at 800 mA. The intelligent LCD panel reports real-time capacity and charging status throughout the cycle. This steady output avoids the current taper seen in many single-bay travel chargers.

Thermal and power characteristics in normal use

The 5 V input draws a maximum of 15 W, keeping heat generation low during typical charging sessions. No active cooling is fitted, so the unit relies on passive dissipation through its compact housing. Operation remains silent, with no fan or audible coil noise. The small footprint and light weight make it easy to pack alongside dive gear.

Questions about this item

Does the charger get hot or noisy when running all day?

The LTD2 charger has no fan and only a small LED display, so it stays quiet and only warms slightly during continuous use.

What cable or power adapter must I already own to power the charger?

You need any 5 V USB source that can deliver 2–3 A, such as a standard phone charger, plus the included Micro-USB cable or your own USB-C cable.

Will the SLB-10A battery work in my older SeaLife DC2000 housing without firmware issues?

The battery matches the original 3.7 V 1400 mAh specification, so it fits and communicates normally with the DC2000.
