I have a bunch of 7day shop rechargeble batteries that I have been using for quite a while and they have been fine.
Ahh. but do you have a battery analyser which can measure their actual capacities? My Maha C9000 showed 7dayshop 2800mAh rechargeables to be horrendously overrated and extremely inconsistent. Some of the cells retained less than 1500mAh immediately after a full charge, whilst the best ones only reached 2100mAh.I have a bunch of 7day shop rechargeble batteries that I have been using for quite a while and they have been fine.
I had 3 Sandisk 8GB SDHC Cards fail on me four years ago. I will never use Sandisk again. I changed brands and have never had an issue since.If you want ultimate reliability then Samdisk's reputation is second to none
