Replacement kit for SeaLife DC2000

This Kastar kit supplies two SLB-10A lithium-ion batteries and an LTD2 dual charger for the SeaLife DC2000 underwater camera. Each cell delivers 3.7 V and 1400 mAh for a total of 5.18 Wh. The bundle suits divers and snorkellers who need spare power for long sessions. It is not for owners of other SeaLife models or cameras that use a different battery form factor.

Charging limited to USB power sources

The LTD2 charger draws 5 V at 2 to 3 A (15 W maximum) through either Micro-USB or USB-C input. It charges one battery at 4.2 V 800 mA or two simultaneously at the same rate per slot. An LCD shows charge status and capacity for each cell. Users without access to a USB power adapter or power bank cannot operate the charger.

1400 mAh capacity per battery

Each SLB-10A cell provides 1400 mAh at 3.7 V, which determines how many shots or minutes of video are possible per dive. The fixed capacity means heavy shooters must carry both spares or recharge between dives. Buyers who need longer run-time per battery should look for higher-capacity alternatives.

Questions about this item

Should I pick the 2-pack or a single battery for the DC2000?

The pack includes two 1400mAh batteries and a dual charger so you can run one while the other charges, which is the only configuration offered.

What does the 5.18 Wh rating mean for dive time on the DC2000?

At 3.7 V and 1400 mAh each battery delivers 5.18 Wh, giving roughly the same energy as the original SeaLife cell for comparable dive duration.

How fast does the LTD2 charger refill a battery over USB?

The charger draws 5 V 2-3 A and outputs 4.2 V at 800 mA per slot, so one battery takes about two hours and two together about the same.
