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

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.
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.
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.
These are good for 9V applications, but you must remember when you put them in as they self discharge. But definitely worth a buy!!
