The CH4040 dual bay, simultaneous smart charger is a standalone unit which provides the capability to carry out charging on any two “N-Series” Inspired Energy batteries at the same time. The CH4040 works with every smart, standard Li Ion and NiMH battery in the Inspired Energy “N-Series” portfolio irrespective of size, shape, voltage, or capacity. So you can recharge a 12V NiMH battery and a 3.6V Li Ion battery if you wish. With its multi-voltage power supply, the CH4040 works throughout the world. Variants are available for use in North America (CH4040A) Europe (CH4040E), the UK (CH4040U).

CH4040 REACH, RoHS2, CE & Customs Declarations are available to download from our Shipping Page.

Standard product approvals are listed above. Additional agency testing of these products can be arranged to meet specific testing needs. However, as the manufacture & design authority rests with Inspired Energy, all testing must be undertaken directly between us and the agency. Please contact us for details and pricing

Recharge Times:

Different battery packs will require differing recharge times. The times given are for a full charge from 0% to 100% state of charge. They are valid for all variants and custom hybrids of each battery model. (For example the Ni2020AG has the same recharge time as the Ni2020HD.)

P-Series batteries use a high-current, 7-pin D-sub connector. They are more rugged than the N-Series batteries - some of them are IP65-rated - they also are optimized for using cells with low internal impedance which excel in low temperature and high discharge current applications. They require the use of a "PH" series charger.
N-Series batteries use a 5-blade standard battery connector. They are optimized for using high capacity cells for maximum runtime. They require the use of a "CH" series charger.
