Kastar NP-F990 Battery 2-Pack and LTD2 USB Charger - High Capacity

In this review the Kastar NP-F990 Battery 2-Pack with the LTD2 USB dual charger is evaluated for users who need long runtime for older Sony camcorders. The bottom line: it is a practical replacement set offering a large 11600mAh lithium-ion capacity per cell and flexible charging options, so videographers who shoot long events or travel will appreciate the runtime and convenience. The kit pairs two batteries with a compact USB charger that supports both Micro-USB and Type-C input and an intelligent LED readout for clear charge status.

Key Features

• High capacity battery: 11600mAh at 7.2V provides extended runtime so users can record longer sessions between swaps.
• Dual charging: The LTD2 charger can charge two batteries simultaneously, reducing downtime when preparing for shoots.
• USB powered convenience: Charger accepts Micro-USB and Type-C input at 5V 2-3A, making it easy to top up from common power banks or adapters.
• Interchangeable plates: The charger allows plate changes to support different battery models, adding flexibility for mixed gear setups.
• Charging indicator: Intelligent LED display shows charging status and battery capacity so you can monitor charge progress at a glance.

Who It's For

This kit is aimed at owners of legacy Sony camcorders that accept NP-F series packs, especially those who shoot long-form content such as weddings, events, or documentary segments and need reliable, high-capacity replacements. The large 11600mAh cells cut the number of battery swaps and the USB charger makes it simple to recharge in the field.

It is less suitable for users who require original-brand warranty support or those with cameras that use different battery chemistries or voltages. If you need OEM batteries with manufacturer certification, you should look elsewhere.

Pros & Cons

Pros

• Very high capacity extends run times compared with many stock packs.
• Charger can top two batteries at once, saving time between shoots.
• USB input and included Micro-USB cable enable flexible charging from adapters and power banks.

Cons

• Not an OEM Sony battery, so users seeking brand-original packs may prefer manufacturer units.
• The charger output is modest at 800mA per bay, so charging two depleted batteries can take several hours.
