A new battery type has appeared:

Advantages:

  • 1000+ (dis)charge deep-cycles.
  • Low self-discharge; 5% / month at 25 deg. celcius
  • Very electrically robust
  • Very mechanically robust - can literally be nailed without explosion danger.
  • -30...60 deg. celcius operating
  • a123systems ANR26650M1 3.3V 2.3Ah can be charged in 15 minutes.
  • a123systems ANR26650M1 3.3V 2.3Ah cells are laserwelded instead of crimping, which lower water losses and therefore extends celllife.
