The Search and Rescue uses four plastic battery carriers (or canisters) that carry 3 batteries each, (except for one dummy battery).
The batteries are taken out of the carriers to recharge in a multi- battery capacity charger, such as the Vanson 10 bays or the Maha 808.
Here is a picture of the 10 bay charger,
Here is a picture of three of the canisters (battery carriers) in the BOREALIS these carriers give 951 lumens, more information on the version # 1 of the BOREALIS which use these carriers is in my web site.
One of the others carriers is the "Cadillac" it keeps the batteries all together, lowering resistance and producing 1050 lumens, it charge easily by using the charging rods.
The alligators from the RC Fast or Slow chargers, clip to the charging rods in the Cadillac battery carrier.
The most convenient way to charge, is with the Rolls Royce battery carrier, the RC Fast or the RC slow chargers (pulse and reverse pulse charging will not heat the batteries) will plug into the charging port of the Rolls Royce and will charge the batteries in 1 1/2 hours or 3 hours (with the settings in the RC FAST charger) or in 4 1/2 hours in the RC Slow charger.
Here is a picture of the set up, RC FAST charger and Rolls Royce.
And here is a close up of the charging port in the Rolls Royce battery carrier.
The new Powerex 2700 mah batteries that I am using now, will give the BOREALIS a 50 minutes run time (after a few charges-discharges, up from 45 minutes) and the new batteries seem to have a much lower self discharge rate, of about .50 % per day.
Still, if the light is in the shelf without beign used, I charge it every time I pay the phone bill, the same day I unload the full magazines to rest the spring for a month.
Nimhs batteries don't have a memory, so you can top them at any time, even if you use the light for 15 minutes today, you can quick charge them, so tomorrow you start with a full charge.
Think about it, you can not do that with alkaline batteries!
Since we are talking about the batteries, the manufacturer says that the batteries will last for 1,000 recharges.
At 50 minutes per charge a set of 9 batteries for the BOREALIS will last for 833 hours, before a new pack of $30.00 is needed.
Since this light was conceived to be in direct competition with the Surefire M-6, (500 lumens, 20 minutes run time on six 123's batteries), at $2.00 per 123 battery a cost of $12.00 per 20 minutes and $36.00 per hour.
It is clear that before the M-6 can run for 833 hours, it will have spent $29.988 in batteries!!
