need new battery

Hi All,
I currently have a fenix cl25r lanter which came with an ARB-L2-2300 battery. I want to get a higher capacity one. Are there any around that i can use that will still let me charge the battery inside the lantern?

Thanks.
Pete

Yes, lots of choices. I gave the protected Fenix battery to my son-in-law for his lantern as a spare and I just use unprotected 3400mAh green flat top Panasonic NCR18650B in it because I had a few of them. A 3500mAh NCR18650GA battery fits fine along with any protected batteries. Springs on both ends means the battery does not have to have a button top. Lots of choices. Since the built in charger charges up to 4.20v, I wouldn't use any of the 4.35v batteries.........but mostly what you will come across are likely to be the 4.20v Panasonic based cells.
