Compatible battery kit for Lawmate and RCA recorders

This set supplies four replacement lithium-ion cells and a dual-bay USB charger for Lawmate PV-1000, PV-700, PV-800 and PV-806 recorders plus RCA Lyra X2400 and Thomson X-2400 players. Each cell delivers 3.7 V and 2300 mAh for 8.51 Wh capacity. The pack suits operators who need ready spares for extended field recording sessions.

Charging limited to two cells at 800 mA each

The LTD2 charger powers two batteries simultaneously at 800 mA per bay from a 5 V 2-3 A source. Micro-USB and Type-C inputs accept common power banks or wall adapters, but the fixed 15 W input ceiling means charge time cannot be reduced further. Users needing to replenish all four cells must run two sequential cycles.

Compact charger with swappable plates and LCD status

The charger body measures 5 by 3 by 3 inches and includes an LCD that shows voltage, current and capacity per bay. Interchangeable plates let the same unit serve other battery models, reducing kit bulk for multi-device crews. A short Micro-USB cable is supplied; Type-C cables must be provided separately.

Questions about this item

Should I choose the four-battery pack or buy single cells?

The pack includes four 2300 mAh 3.7 V Li-Ion cells and one dual-slot charger, so you can cycle spares without waiting for a single battery to recharge.

What does the 8.51 Wh rating mean for actual recording time?

At 3.7 V and 2300 mAh each cell stores 8.51 Wh, giving roughly the same run-time as the original RD2400A-BAT in a PV-1000 or Lyra X2400.

How fast does the USB-C or Micro-USB input actually charge the batteries?

The charger draws 5 V at up to 3 A (15 W) and delivers 4.2 V at 800 mA per slot, so two batteries charge simultaneously at that rate.
