Cost effective rechargable 9v – BTY 280mAh Ni-MH 9V Rechargeable Battery Reviews

Pros:
These are quite good 9V nimh rechargeable batteries. They hold their charge quite well after fully charging and open cell voltage is 9.2VCD. They have average self discharge times.
Cons:
One of my batteries came with a bit of oxidation on the terminals, so I had to sand it a bit to get them clean.
Other:
For standard Nimh 9V rechargeables, these are very decent and cost effective. The only thing is I wish they were low self discharge for the same price, as most 9V applications use low power levels and stay in the device for long periods.
Bottomline:
These are good for 9V applications, but you must remember when you put them in as they self discharge. But definitely worth a buy!!
