Kastar NP-FM500H 2400mAh battery

This kit supplies a lithium-ion replacement battery rated at 7.4 V and 2400 mAh alongside a dual-slot USB charger. It targets photographers using compatible Sony Alpha and SLT bodies who need a spare power source and a convenient way to recharge without a dedicated AC adapter. The bundle suits travel and field work where USB power is readily available.

Dual USB charging with LCD status display

The LTD2 charger accepts 5 V input via Micro-USB or USB Type-C and can charge two NP-FM500H cells simultaneously at 800 mA each or a single cell at 800 mA. An integrated LCD panel shows real-time charging progress and remaining capacity for each slot. Maximum input power is 15 W, keeping heat and fan noise absent during normal operation.

Sustained charging cycles and capacity retention

Under continuous use the charger maintains its 8.4 V output across both channels without throttling, allowing back-to-back cycles for extended shoots. The 7.76 Wh battery delivers consistent voltage until depletion, supporting long sessions on compatible models such as the Alpha 77 II, Alpha 99 and A700 series. No active cooling is required, so silent operation persists throughout heavy workloads.

Questions about this item

How do I install the NP-FM500H battery into the LTD2 charger and what step do people often miss?

Insert the battery so its contacts align with the charger pins, then connect the charger to a 5V 2-3A USB source via Micro-USB or Type-C; the step often missed is ensuring the power source actually delivers 2-3A, otherwise the 800mA per-slot output cannot be maintained.

What maintenance or replacement will the Kastar NP-FM500H 2400mAh Li-Ion battery need later?

The 7.4V 2400mAh lithium-ion cell gradually loses capacity over charge cycles; plan to replace the battery when run-time drops below your needs, and keep the charger's LCD contacts clean for accurate status reading.

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

The charger's total 15W input ceiling limits dual-slot charging to 800mA per battery, so extended sessions are constrained by that 8.4V 800mA x2 output rather than the 7.76Wh cell capacity.
