    Watson D-LI109 reviews

    D-LI109 Lithium-Ion Battery Pack (7.4V, 1050mAh) is rated 4.9 out of 5 by 29.
    Rated 4 out of 5 by from Nice Battery The Pentax K-r drains batteries quick. I'm impressed by this batteries refusal to die. I'd recommend two of these as a better investment than one new Pentax Li-109 battery.

    Rated 5 out of 5 by from Same performance as the original. For less than half the cost, this battery performs like my original Pentax battery. I'm very confident to have it as my back-up.

    Rated 5 out of 5 by from Buy this battery After having used these batteries, I'm not entirely sure why anyone would spend 3x more on the Pentax brand. This battery is a perfect replacement. It charges just as fast, and from my experience lasts just about as long. I haven't yet found a downside to this battery. (maybe the overall lifespan of the battery is less?) That would be my only guess. I bought two of these as backups for my multi-day backpacking trips and I am quite satisfied. At this price point, and the quality you get, this is a no brainer.

    Rated 5 out of 5 by from As good as the original The Watson lithium-ion battery seems to work just like the Pentax one, and it's considerably cheaper. Duration is similar, and build quality appears good.

    Rated 4 out of 5 by from Good alternative for Pexnax brand batteries I have used this battery for two days only, so my review may not be perfect. I have purchased this battery as my original Pentax battery that came with the K30 was not able to hold up the charge any more and could go from 100 to 0 at no time. So far this battery seems to be good, just like the new and original Pentax. I had shot more than 150 clicks with a single charge on my Pnetax K30 and still around 50% charge remains. I can not comment on how long the battery will sustain this charge or how long it can perform well. Still now I am satisfied and this satisfies my need.
