| 1211801 | 2011-06-27 01:34:00 | I'd like to mention the best thing you can do to make your rechargeables last is use a decent charger, don't use a timer based one or a cheap constant current type. you never know how charged your batteries actually are. A modern smart charger with a delta V cut-off is the best way. I just recently purchased some low discharge eneloop batteries myself, seems despite the lower mAH ratings they last much better than regular NiMH batteries in almost every case. The exception being applications where you take a freshly charged set of batteries and immediately use them until flat. Otherwise the regular ones self discharge very quickly to lower capacities. |

If you use lots of D size batteries, these are definitely worth a try! Usually offered to commercial or industrial users we can offer you these batteries at a fraction of the cost of the consumer packed Duracell Plus equivalent. " Just the same performance not "infinitely better". |

Its best to get one with independent charging circuits so each battery is charged to capacity. Also high speed chargers damage batteries as they increase the temperature which shortens battery life. |
