Kastar NP-FM500H Battery (2-Pack) for Sony DSLR-A100 A200 A300 A350 A450 A500 A550 A560 A580 A700 A850 A900 Alpha SLT A57 A58 A65 A65V A77 A77V A77 II A77M2 A99 A99V CLM-V55 Cameras

Holds a charge well. High capacity. Seems to be more powerful than original Sony, which are still very good. This brand looks to be the one to get. I wish the Minolta/Sony flash units were designed for these batteries or they somehow ran off them. I'm very pleased with them, but I won't need to by more for a long time if ever. They're running my A65 and A58. These cameras are from 2016 and 2013. It's great to be able to get high quality batteries for them.

A good replacement for OEM battery. No problems in my Sony a77II Camera.

These have a good to them and bad. First off and it only happen with these brand. My regular sony brand do not do these. The bad for all the once I have from this brand they do not show the correct % of how much battery life is left in them. It will start off at 100% and then in a while it drops down to 98% and stay at until the battery runs out. The good part is even when it does not show the % on them I do feel they have more power then the sony brand do. Sonya rated for 1600 something like that and these are rated at 2400. I ordered 2 the first time and with out using them ordered 3 more. Today I had a photo shoot and used kaster first lasted about 1hr and a half of almost none stop. Camera turned off because I couldnt tell what % they are so I took it out and put a sony. Still busy and the Sony lasted about 45min. Felt the Sony didnt give me the time/picture amount I wanted so when it ran out I put in a kaster and finished the shoot with it. Since it slowed down I was didnt have to switch it out. If they last me a while and dont completely die on me I'll keep buying this brand. I dont need the % since I have plenty of back up batteries and switching them out is not a problem since I'll have to switch them out less then i would with the sony name brand.

Better than oiginal

GREAT DEAL

I purchased these batteries as an alternative to Sony batteries. The problem I ran into is that they don't fully charge. One charged up 70% and the other to 75%. I'm returning them.

I got these for an old Sony DSLR that I'm giving to my Nephew. It has a grip for the extra battery so the two pack deal was great.

These Batteries are good for backup/in case of emergency. I wouldn't recommend using them on assignments, they will embarrass you

EXCELENTE PRODUCTO CALIDAD, DURACION Y PRECIO

el precio es adecuado y son muy útiles para tener carga extra en sesiones de fotos de larga duración

BUENO CON MEJOR PRESIO

Me parece que la duración es un poquito menor que las originales, pero por el precio, no hay la menor queja

Horribles baterías no cargan nada
