Synergy Digital Camera Batteries Compatible with Casio NP-90 - Pack

In this review the Synergy Digital replacement battery pack is evaluated for photographers who need reliable spare power for older Casio Exilim cameras. The bottom line: this set of four li-ion batteries (3.7V, 1950 mAh) is aimed at hobbyists and prosumers who need multiple full-capacity spares without paying dealer prices. The reviewer found the cells to be physically compatible, offer solid run time comparable to original packs, and include a reassuring three year warranty, which is the single biggest reason to consider this pack for extended field use.

Key Features

• High capacity: Each battery is 1950 mAh, providing comparable run time to many original NP-90 packs for longer shooting sessions between charges.
• Broad compatibility: The pack works with Casio NP-90, NP-90DBA and NP90 cameras and several third-party replacements, reducing worry about fit or electronics mismatch.
• Japanese cells: Made with high quality Japanese cells, the batteries feel consistent and stable during repeated use.
• Compact, lightweight: At roughly 1.34 x 2.06 x 0.45 in and 1.3 oz each, the batteries are easy to carry as spares without significant bulk.
• Three year warranty: The included warranty gives peace of mind for longer ownership and protects against early defects.

Who It's For

Photographers still using Casio Exilim models such as the EX-FH100, EX-H10, EX-H15 or EX-H20G will get the most value from this pack, especially if they shoot events, travel, or long outings where swapping batteries matters. The set of four is practical for someone who wants multiple charged spares without having to wait to recharge between shoots.

Those who demand official manufacturer-branded batteries or need batteries for cameras outside the listed compatibility should look elsewhere. Also, users who require proprietary fast charging or in-camera battery health reporting might prefer original-brand packs.
