This is the 4th generation of Eneloop rechargeable batteries (BK-3MCEE) with up to 2100 charge cycles. They loose only 10% of their capacity after 1 year and and they still hold up to 70% after 5 years.
What is "Low-Self-Discharge" technology?
There are a number of people who would have you believe that this is "new technology" & somehow better than all that has gone before. Well here are the facts.....
This technology has been around since 2007 - we have been selling them for that long.
The term low self discharge means that the battery will not run down after being charged anything like as fast as a conventional NiMH or NiCd rechargeable battery would. After being charged, these batteries will typically retain 80% of that charge after 12 months, and 90% after 5 years, this makes them ideal for applications where they receive occasional light use, basically after being left for a couple of months you can just pick up where you left off.
Sounds good? Well as in all things that seem great there is always a catch - this is what the other guys selling this type of battery don't tell you - due to a combination of them not understanding the product & not wanting to lose a sale.
There are principally 3 down-sides:
1) The batteries have a lower capacity than standard NiMH types - typically around 10 - 20% lower. If your batteries get used very frequently, these are not the best choice, you will get better perfomence from the standard 2600mAh types such as the ones we sell.
2) The batteries cannot be fast charged in the same way that conventional NiMH types can. We recommend that these packs be charged at no more than 1,000mA
3) The packs cannot provide the same current output as standard types, so this makes them unsuitable for motor applications, or other high current uses.
Hope that this explanation helps, feel free to ask us any questions & we will get back to you as quickly as we can.
Measured at 400mA (0.2C)
Max Discharge Current:
Limit 3,000mA with Futaba/JST connector
Max Charge Current:
At full charge
This battery pack is supplied as standard with a Futaba style connector on flexible wire.
We can supply this with other connectors such as JST on request, or even with multiple
combinations of connector.
