Li-ion cells have fairly low self-discharge, but in order to prolong the life of the battery, should be stored partially discharged. | Li-ion cells have fairly low self-discharge, but in order to prolong the life of the battery, should be stored partially discharged. | ||
'''Recommended batteries:''' Many CPF members recommend AW (available through some online dealers and directly from AW via [http://www.cpfmarketplace.com/mp/forumdisplay.php?f=13 CPF Marketplace/Dealers] under the latest AW's LiIon Batteries Sales Thread) or Redilast cells (also on CPF) which are of consistently higher quality and have better protection than cheaper cells, but are very expensive ($12 each and up). Both of those brands use Panasonic NCR18650A 3100mAh cells which can also be purchased from other providers (but are still expensive). These are the highest capacity cells available in this size. Trustfire has a line of li-ion batteries with flames on the label that are a decent budget alternative in nominal capacities of 2400 or 3000 mAh though actual capacity will be less, however it is hard to find genuine ones even at DealExtreme which has been a reliable source in the past. eBay is a notoriously bad place to buy lithium ion batteries, with fake brand name batteries and false claims regarding capacity and battery protection. XTAR (using 2600mAh Sanyo cells) and Hi Max (using 2600 mAh Samsung cells) brands are better than Trustfire, but cost a little more ($7 each for XTARs via this [http://budgetlightforum.com/node/2476 BLF thread]).
