elxjar (3-Pack) BR-CCF2TH 6V 5000mAh Lithium Replacement Battery for Fanuc oi Mate Model-D, Panasonic Controls, GE Fanuc A06 Series, BR-CCF2TE CNC Coaster (Cutler Hammer), Brown Connector

Work well. Keeps the backups backed up.

Batteries came in a box, one was in a sealed package and was clearly new, the other two were loose in the box, installed batteries in my Hardinge VMC and one of the batteries was dead, couldn't have been a new battery. Disappointed, caused the machine's drive to fault out and had to re-zero two axis, lost hours of machine time that shouldn't have happened if battery was new.

Perfect fit, no issues. Change while the machine is on.

I needed these for my Fanuc control, the local battery supplier said they needed a week to bring in. I purchased the 3-pack of batteries, inserted 2 into the drive units (yes while powered up). The following morning I had a battery error, lost home position and parameters. I took the batteries to the local supplier and they said 2 were weak, below nominal voltage, and 1 was dead. I'll use the 2 weak ones to get by for a few days until the local supplier can get me new ones, then I'm sending them back.

FYIThe latest batch from Amazon were not Panasonic BR-C cells. They were 26500 Cells ie 26mm dia x 50mm long The outside is 2mm longer (even with + terminal bump) than the BR-C sell and have to be forced to fit in Fanuc drives. Date on the BR-CCF2TF pack was marked 2024-05-27, so 6 months old when purchased. If the cell quality and life is good I might be able to live with this. The new ones measure 6.4v while this older one measures 7.0v 3.0 vs 3.6 (Li-MnO2 vs Li-SOCl2) battery chemistries?Time will tell if this works ok other than the fit.

Great product, I would order this again

Have purchased these multiple times, however just purchased a pair in April and one of them failed within a week. Returned for replacement and both replacement batteries died this past weekend after just 2 months. These should be lasting a year no problem, now I get to waste time re-zeroing my machine a second time in 2 months.

Short life and some were failed out of the box. Total trash. had sudden failures in machines causing us to have to reset home positions.
