I got some from Batteryworx in Onehunga. They repack power tool batteries. The batteries have no brand on them but the guy reckoned they are as good as you can get (reckoned there was no point in using anything else as the labour cost of re packing is 90% of the cost). They last as long as the NCR ones I got, and we're only $6 each. They are flat top, but I just siliconed a copper washer on one.
