KastarFast Dual LCD Charger + 2X Battery for Pentax Ei-D-Li1 EI-D-BC1 Pentax EI-2000, Trimble 29518 46607 52030 54344 38403 5700 5800 R6 R7 R8 GNSS TR-R8 GPS, HP C8873A HP PhotoSmart 912 C912C912XI

Battery works like a trimble r8 battery. Roughly 4hours of run time while surveying.Charger comes with a 12V DC plug in. Great for charging on the go.I recommend this product for both proce and performance

Works great!!! Needed something to keep my devices charged while in the field. My only regret was waiting so long to finally buy one! At this price EVERYONE should have one of these! No longer have to haul my equipment in and out very morning/evening just to plug in. Life saver!

Batteries are too thick to fit in a MT1000. They will stick when inserted and won't be able to be retrieved if they go in past the locking clips. Batteries should effectively "fall out" once the clips are released. If not, they will be held in too tightly to easily remove. CAVEAT EMPTOR.

My work owns a Trimble R2 GNSS receiver, and the charger for it recently died. The replacement charger from Trimble was listed multiple places for over $500, so I did some research and found this. For about a tenth of the price I got a better charger and two more batteries. The batteries and charger feel and look the same quality as the expensive Trimble products. Would highly recommend.

I did not want to pay OEM prices of $120 each for these common battery packs. We have 3 Spectra Precision SP80s, 2 batteries each would have been over $700, for less than half the cost of an OEM battery you get 2 batteries and a charger. The chargers that come with the SP80's are proprietary to their batteries, these are the only aftermarket batteries that will fit in that charger, albeit a little tight but works. These batteries are roughly a 1/16" thicker than the OEM batteries. All the aftermarket batteries I have used have no problem fitting in the battery compartment of the SP80. I have another set of, different manufacture, batteries and they have the same life span as the OEM ones, I've had those for over a year and still going strong.

Don’t waste money on TrimbleThese are awesome and the charger works every time

Excellent shipper - product is as described

Purchased this battery attempted to charge multiple times it never charged and never worked
