Kastar LB-060 Kit for Rekam Cameras

This four-battery pack with an LTD2 dual charger serves owners of Rekam BIZZARO HDC-2531, HDC-2532 and PREZIO HDC-3531, HDC-3533, HDC-3535 camcorders. Each 3.7V lithium-ion cell stores 1700mAh for extended recording sessions. The charger accepts both Micro-USB and Type-C power inputs, so you can top up from common USB sources without a proprietary wall wart.

Thermals, Noise and Power Draw

The charger draws up to 15W from a 5V 2-3A USB supply and delivers 4.2V at 800mA per slot, charging two batteries simultaneously. No fan is present, so operation is silent. The LCD panel shows real-time capacity and charging status for each cell, letting you monitor progress without guesswork. Heat remains low during normal top-ups thanks to the modest charge current.

Behaviour Under Sustained Load

During back-to-back charging cycles the unit maintains steady 800mA output per channel without throttling, so the fourth battery reaches the same 6.29 Wh capacity as the first. The intelligent controller balances current between the two slots, preventing one cell from starving the other. Users who need more than four ready cells or faster than 800mA per battery will require additional chargers.

Questions about this item

How do I install the batteries into the LTD2 charger and which orientation mistake should I avoid?

Insert each LB-060 pack with the gold contacts facing the charger pins; the LCD shows a battery icon only when polarity is correct.

What part will need replacement first during long-term use of this kit?

The four 1700mAh Li-Ion cells degrade before the LTD2 charger; expect to buy fresh LB-060 packs when run-time drops noticeably.

What limit appears first when the charger runs continuously at its 15W input rating?

The 800mA per-slot output caps current, so two batteries charge at 800mA each even though the 5V 2-3A supply could deliver more.
