A bit like how a 3000mAh IMR 18650 can give better runtimes than a 3500mAh one under certain conditions. These are small, dry-cell, rechargeable batteries that are used in cell phones, power tools, laptops, video cameras, etc. Find low everyday prices and buy online for delivery or in-store pick-up. I wonder if the fans were probably taxing the batteries a bit harder. DURACELL Rechargeable AA 2500mAh Battery. Shop for 18650 battery 3.7v 3000mah lithium-ion rechargeable batteries at Best Buy. The discharge test was controlled at a fairly lowish amp draw. Smartoools 1.5v Li-Ion AA (haven’t tested yet).Xtar 1.5v Li-Ion AA ~ 1926mAh (03hrs 51 min) Kratax 1.5V Rechargeable Lithium AA Batteries, 12 Pack AA Li-ion Batteries with 2H Smart Fast Charge, 3500mWh High-Capacity, 1600 Cycles, Long-Lasting, Constant Output for Household Office Devices.I got these results (first charge each to full), MC3000 set to –0.50A discharge current: The XTAR 1.5V AA 3300mWh Battery is a high-performance rechargeable battery designed to provide reliable power for various devices. On second try with the MC3000, I connected to the PC so I can check the discharge graph, before it displays the “Connection Break” error. So far, I’ve been able to source these 4 models: Vapcell P1418A, Smartoools 1.5v Li-Ion AA (these 2 are reviewed in the video), Xtar 1.5v Li-Ion AA (would like to request the reviewer above to check out this battery too), and also a less-well-performing DoublePow (I ordered 4pcs, and 1 of them came malfunctioning… so this is not a good brand)…Īt first, I tried using SkyRC MC3000 to do a discharge test (after fully charging each of them), but unfortunately, the MC3000 will report “Connection Break” error when the battery is completely depleted (drops to 0.0v), so it looks like ordinary charge/discharger don’t seem to work (I also tried another analyzing charger, and they don’t like the “drop to 0.0v” - capacity test will disappear when that happens. What is more interesting is the Smartoools battery - it’s about middle-of-the-pack in terms of tested capacity, but it outlasted all the others (which have higher tested discharge capacity) in the “fan” runtime test, except for the Vapcell (which outlasted all others). What I find interesting is the “fan” test in the above video - apparently, the discharged capacity test may not completely equate to the “fan” runtime - the Vapcell has the most tested capacity (just a bit more capacity when compared to some of the better models in the test, but the “fan” runtime is significantly a LOT longer). I’ve also been itching to find out how these 1.5v Li-Ion AA rechargeable batteries perform. The2500mAh of the AA size battery is identical, and the Duracell AAA battery isn’t far behind, at 900mAh compared with 930mAh for the Eneloop Pro.
