Four 2400mAh Li-Ion batteries with dual USB charger

This kit includes four NP-FM500H lithium-ion cells and an LTD2 charger that powers two batteries at once. Each cell delivers 7.4 volts and 2400 milliampere-hours for compatible Sony Alpha and DSLR bodies. The package suits photographers who want spare power for long shooting days. Micro-USB and Type-C inputs let you recharge from common USB sources.

Intelligent LCD shows capacity while drawing 15

The charger accepts 5 volts at 2 to 3 amperes and supplies 8.4 volts at 800 milliamperes per slot. An LCD panel reports real-time charge level for each battery during the cycle. Operation stays quiet and cool because the unit has no moving parts. The 7.76 watt-hour rating per cell keeps the kit light for travel bags.

Sustained charging tops both cells without throttle

Under continuous use the dual slots maintain their 800 milliampere output until both batteries reach full capacity. The intelligent controller balances current so neither slot slows down as voltage rises. Photographers who need more than four cells or a faster charge rate will need additional chargers or higher-current power adapters.

Questions about this item

How do I install the NP-FM500H batteries and the LTD2 charger, and what step do people often get wrong?

Insert each 7.4 V 2400 mAh battery into the dual-slot charger, connect the Micro-USB or Type-C cable to a 5 V 2-3 A source, and ensure both batteries click fully into the interchangeable plates so the LCD shows charging status for each cell.

What maintenance or replacement will the NP-FM500H batteries need later?

Lithium-ion cells degrade with cycles; expect reduced run-time after several hundred charges, so plan to replace the four-pack when capacity drops below usable levels for your Sony Alpha models.

What limit appears first during sustained charging of two NP-FM500H batteries on the LTD2 charger?

The charger outputs 8.4 V at 800 mA per slot when both bays are occupied, so total charge current is capped at 800 mA per battery, extending full-charge time compared to single-bay charging.
