Kastar NP-BY1 Battery and Quad Charger

The Kastar NP-BY1 kit includes one 1100mAh 3.7V lithium-ion battery and a compact charger that powers up to four cells simultaneously. It suits owners of compatible Sony, Pentax, Ricoh and Sanyo compact cameras who need spare power for extended shooting sessions.

Replaces OEM D-LI78 and NP-BY1 cells

This pack directly substitutes the original Pentax D-LI78 and Sony NP-BY1 batteries used in models such as the Optio W60, W80 and HDR-AZ1. The jump is worth it when you want a single charger that handles four batteries at once instead of charging them one by one with the stock adapter.

Sustained charging behaviour

The charger accepts 5V 2-3A input via Micro-USB or USB-C and delivers 4.2V at 800mA for one or two batteries, dropping to 500mA each when three or four are loaded. An onboard display shows real-time capacity so you can track progress during long top-up cycles.

Questions about this item

What are the dimensions of the quad charger so I can check if it fits on my desk?

The charger measures 3.5 by 2 by 2.5 inches, making it compact enough for most work surfaces.

How do I swap the charging plates to fit different battery models?

Slide the current plate off the charger rails, align the replacement plate for your battery type, and press it firmly into place until it clicks.

When should I replace the 1100mAh Li-Ion battery?

Replace the pack when run time falls well below the original 4.07 Wh rating or the charger shows a persistent fault indicator for that cell.
