Pentax is building great cameras and it is worth having a second battery I can count on.  I can't speak for the third party batteries but the Pentax battery works great.

Pentax 645D battery

I bought this as a backup. I?ve charged it and not used it yet because the original battery charge last a long time.

Extra Battery

Lasts Longer

Nothing much to say, as a spare battery it does exactly what you expect and need, offer additional shooting time in the field.  I have done much better with the original party equipment than the 3rd party options and so am very happy with it.

Extended battery life

Great Battery

Lasts longer than the off brand battery. I balked at the price, but this battery functions way better than the cheaper non-branded one. I'm happy with it! Spend the money, get this one.

Spend the Money

It’s a battery, alright!

It stores electricity for use away from connection to the power grid. It fits in my Pentax for this purpose. Eventually all the stored electricity gets used. But then you can fill it up again. A marvel of the modern era.

Literally stores electricity.

The battery that came with my K3-II didn't last very long. I bought a second battery awhile back that was supposed to be OEM Pentax, but was a Chinese POS. I decided to replace both batteries with real Pentax product. Right out of the box they were fully charged. My old batteries were freshly charged, unused, and already half dead. They are now recycled.

Back in Business

I received my Pentax battery in a timely manner.   I have always love the service from Adorama!  I am a customer for life.

Timely Service and Quality Products

Sorry guys, but you sent me the wrong battery, you did however refund my money although I had to pay to ship back the battery.And FYI, your online representative assured me the battery would fit my camera before I placed the order.

Not the greatest.

I know there are less expensive alternatives out there, but stick with OEMs for your batteries. I have had good luck with other brands but nothing has ever lasted as long (in terms of length of service, not charge time) than Pentax batteries. It's worth the price!

ALWAYS Buy OEM Pentax Batteries!

It’s great

I purchased this as a spare to replace a 3rd party (off brand) battery which doesn't hold a charge for long after about 4 months use. The original Pentax battery still holds a charge great so I decided to purchase the Pentax brand since the original is still going strong after a year and a half of use.
I would also say that I'm very pleased for Adorama's customer support that corrected an issue with a coupon that I had wanted applied at the time of this sale they corrected the issue very quickly.
So overall it's Five stars for the battery and Ten stars for Adorama's customer support.

Very happy with the Pentax D-LI90

Never have had a problem with Pentax battery's.  Maintain their charge so there is no anxiety on a shoot.  Long life in my K5-IIs.

Brand Name Will Perform Longer

This battery, being the Pentax brand just like the one that comes with the camera, works just like it was designed to work.  It holds a charge well, and has not been discharging  too quickly. It seems to be just as good as the original!

Works great!  Lasts long!

Price was reasonable. Communications from Adorama were fine. Unfortunately, I planned to take the battery as a spare on a trip to Italy. Battery was back-ordered and finally arrived after I had left on the trip.

Battery was back-ordered and finally arrived after I had left on the trip

Through experience I have found it is better to spend the extra for the original manufactures battery. Sure the off brand ones work and the charge faster but run down faster and after a short ting the get even worse.

As good as the one that came with the camera.

Good price for OEM battery

I don't have any experience with the off brand batteries, so it's hard to compare. The original battery that came with my k3 never held a charge as long as this one. I'm definitely satisfied with my purchase. Thanks Adorama!

Exactly what I wanted!

The knock off version of the battery is a mistake - the original Pentax battery holds a charge way longer and won't fail you!

Get the original

I have owned many differnt Pentax digital cameras over the years and have always purchased the Pentax brand batteries.  They maintain their charge well and last a long time when I am shooting. I always have an extra battery when I am shooting for the day and have yet to find myself without enough power to finish the day.

A battery is a battery, right? No! The cheaper generic ones fail after moderate use, but the Pentax batteries I've used more than five years are still at full strength. This purchase is a backup for my new cameras.

Genuine Pentax is the best

I received this battery about a week ago and it is the genuine pentax part. I charged it once and probably won't have to charge it again for a month. I shoot a few shots a week normally, not photoshoots.  I've had the original battery for almost 2 years and only noticed a slight degradation. Great batteries!

Quality Pentax product

Pentax D-L190

You can buy a cheaper battery that is compatible with the Pentax D-LI90 battery.  In fact, Adorama will sell you such a battery, and it's not a bad battery at all.  But a charge on it will not last as long, and the worst thing you can have when out shooting pictures is to wonder of the current or backup battery has enough charge to last.

With my K5 I typically utilize Pentax's D-BG4 battery grip (also fits the K7) set so that it will automatically draw from the battery in the camer and that in the grip. It also has an insert so you can use 4 AA cells.  If you want to see how fast a good camera can eat up a non-rechargeable gattery, use that, but make sure you have lots of spares on hand. 

My sense is the Pentax D-LI90 is worth every penny, just for pezce of mind alone.   I was willing to wait over a month while this battery was on back order.

worth every penny!

It's a a very well-made battery that I consider a necessity. I have this one and the one that came with my K-5. It's important for me to always have a fresh battery at the ready and this one fulfills that need admirably.

Works well and reliably.

This battery has exceeded my expectations in longevity. My entire trip to Montreal (4 days) of day and night shooting on a single charge - that about 400-500 pictures.

Outstanding!

Bought this as a 2nd battery for my K-5, very happy with it, performs perfectly.

Excellent Battery

This product is great for a those who need a fast refresh rate for the next picture.

Have no worries friend, this is an incredible
performer.
