Kastar 4-Pack Battery and LTD2 USB Charger Replacement for Sony A350

In this review the Kastar 4-Pack Battery and LTD2 USB Charger replacement is evaluated for photographers who still use Sony Alpha DSLR models that accept the NP-FM500H cell. The bottom line is simple: this kit is for shooters who need multiple high-capacity spares and a flexible USB charger to keep shooting without scrambling for mains power. The review focuses on battery life, charging convenience and compatibility with older Sony DSLR bodies, and highlights that the pack includes a Micro-USB cable and dual charging options for field use.

Key Features

• High capacity batteries: Each lithium-ion pack is 2400mAh at 7.4V, offering extended shooting time compared with lower-capacity replacements.
• Dual battery charging: The LTD2 charger can charge two batteries at once, so spares are ready faster between shoots.
• Switchable charging plate: The charger plate can be changed to accept different compatible battery plates, improving versatility for multiple camera models.
• USB power input: The charger accepts Micro-USB and Type-C input and includes a Micro-USB cable, making it easy to charge from a power bank or laptop when AC power is not available.
• Intelligent LED display: LEDs show charging status and relative battery capacity so you know when a pack is ready to use.
• Compact and portable: The charger is lightweight and simple to carry in a camera bag, useful for travel and location work.

Who It's For

This kit is aimed at owners of older Sony Alpha DSLR bodies that use the NP-FM500H battery, such as the DSLR-A350 and nearby models, who need multiple spares for extended shoots or travel. Hobbyists, event shooters and enthusiasts who prefer carrying several ready batteries rather than pausing to recharge will appreciate the 4-pack approach and dual charging capability.

Photographers who require manufacturer-authorized accessories, fast proprietary charging with AC-only adapters, or the absolute fastest recovery from dead packs should look elsewhere; this kit favors convenience, capacity and USB flexibility over OEM branding or specialized high-speed charging systems.
