Tenergy 4 Pack 3.7V 750mAh Rechargeable Batteries and Charger - Works

In this review the reviewer examines the Tenergy 4 Pack 3.7V 750mAh Rechargeable Batteries and LCD charger bundle, aimed at Arlo camera owners who want a convenient spare set. The bottom line: this kit is most useful for people who need a certified replacement battery solution that is ready to use out of the box and backed by safety certifications. It stands out because it is officially listed as "works with Arlo" and includes an LCD charger, so users get visible charge status and multiple charged cells in a single purchase.

Key Features

• Complete pack: Four 3.7V 750mAh rechargeable batteries plus an LCD charger provide enough spares to rotate through several cameras without searching for separate chargers.
• Arlo compatibility: The batteries are compatible with a range of Arlo models including VMC3030, VMK3200 and several VMS series cameras, which simplifies replacement for those specific cameras.
• Clear charging feedback: The included LCD charger displays charge status so users can tell when each cell is ready to install and avoid guessing times.
• Safety certifications: Batteries carry multiple safety certifications such as UL 1642, UN 38.3 and IEC 62133, giving assurance for safe handling and air transport compliance.
• Charger approvals: The charger is certified to CE, FCC, CEC and UL 1310 standards, which supports reliable electrical performance and regulatory compliance.
• Warranty support: The bundle includes a 12 months warranty from Tenergy, offering recourse if a cell or charger fails in the first year.

Who It's For

This kit is best for current Arlo camera owners who use the listed models and want a straightforward, certified replacement option that includes a charger. It fits people who prefer to keep a charged spare set on hand for quick swaps and those who value visible charge indication via an LCD display.

It may be less suitable for users of Arlo models not listed in the compatibility section or those who need higher capacity batteries for extended runtime; in those cases a different capacity or model-specific solution should be considered.
