Watson D-LI90 Reviews

Good Generic Pentax Battery

By Douglas
Rated 5 out of 5
Date: 2021-05-14

I bought a pair of these for my Pentax K-1ii and they seem to work just fine. They don't seem to last as long as the Pentax brand battery, but they are MUCH cheaper (the 2 cost less than 1 Pentax battery). This way, I'll always have a backup battery.

good for the price

Good as a back up battery but they do not last as long as the OEM battery.

It works but does not hold a charge as long as the Pentax brand and other brands I have used.

Inexpensive battery that works

I have been using this battery for a year and 2000+ shots and have not noticed any fall down. It does not appear to last quite as long as the OEM battery but at less than half the price, a slightly reduced shutter count /charge is worth it. I will buy a couple more for backup.

Great Value!

All the performance of the original Pentax battery at a great price! I bought two of these to replace batteries that became lost.

Solid back-up battery for Pentax K-1

By Sean

I have bought two of these Watson batteries for my Pentax K-1. One about two years ago and the other nearly a year ago. They have worked so far in rather tough situations (hot, cold, wet). I do not believe I get the same shutter count per charge. However, for the price they are good to have on hand as backup; for the price of the OEM battery, one could by two of these.

Good Option

I have used Watson lithium rechargeable batteries for years in Nikon, Fujifilm and Pentax cameras. No problems with battery life, recharging or performance.

Works fine in K3ii

Watson power cells have always worked in my Pentax cameras. I get satisfactory life & results using these in rotation.
