AAA LSD NiMh Battery Section

We have been selling GP cells for more than a decade and have distributed thousands for remote sensing and telemtetry applications where qaulity and reliability are the primary concern.

GP AAA Recyko Cells

These cells are the equivalent of 800 mAh, and surpass the performance of the flagship Eneloop cells that are so popular (as evidenced by these tests performed on CandlePower Forums (click image for larger table):

Pricing: We've matched Costco's package pricing for the Eneloop cells, so ours are packaged in 4 packs and cost $10.95 per pack (which works out to $2.74 per cell). Singles are $3.65 each.

See the AA page for more information about Recyko cells.

Best use scenario...

Avalanche Beacons, WHAT! you say. Yes we are aware that most manufacturers recommend alkaline cells only. But guess why they say that? Consider the following information from pistehors.com: "This is because the circuitry which detects how much battery life remains is tuned for this kind of cell. The capacity of Alkalines degrades gracefully whereas Lithium (and rechargeable cells) have a relatively flat discharge curve. One minute your beacon is saying 99% full, the next it is on zero." OK, so now we know that the reason to use alkalines is because you put them in at the start of the winter and throw them out in the spring.

We also know that a beacon, like any radio transmitter, does not transmit as far when the voltage sags. So would you not prefer to know you have the strongest possible signal in the event of burial? Then you can do so by rethinking the way you do things. Consider putting a fresh set of NiMh batteries in your beacon at the start of every trip instead of at the start of each season. For starters NiMh have way better cold weather perfomance characteristics, and as well if you get benighted and avalanche exposure is no longer a concern as you try to egress, you can power your EDC headlamp.

So it is now 2013 and it's time to rethink battery use rules for beacons that were a good idea a decade ago before the march of battery chemistry progressed to where it is today. The one caveat is to test your battery compartment as some circa 2005 models were very sensitive to size. For example the Ortovox M2 could be deactivated by a slap to the bottom of the beacon because the battery would dislodge. Ortovox at the time recommended that users choose batteries that had a prominent negative base dimple. The Recyko cells have a flat negative base and prominent positive nipple, so just check your beacon's negative contact landing pad to see if it can live happily with a flat ended battery, if it is a modern one it should have no problems, we have been using NiMh in our BCA and Ortovox beacons for years and no problems fo far.

The other recommended use is for the Spark SD73 headlamp.
