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

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

BUENO CON MEJOR PRESIO

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