Christmas is once again approaching, and for those people with kids, that means new toys, and new batteries to power them. While an increasing number of toys use AA batteries, many larger toys need the capacity of a C or D battery. The cost of powering those toys with disposable C or D batteries adds up, and contributes a substantial amount to landfill each year.

Rechargeable C and D batteries solve this problem, providing 3 times the power of disposable batteries, so the toys don’t need the batteries changed as often, and since each battery can be recharged hundreds of times, the landfill is substantially reduced by using rechargeable C and D batteries. Rechargeable C and D batteries are available in High Capacity Powerex C and Powerex D rechargeable batteries, and also as Accupower Low Self Discharge C batteries and Accupower Low Self Discharge D batteries. LSD batteries are great for toys and other devices which are not used regularly. The lower self-discharge rate of these batteries means they are ready to use when you need them, and are perfect for use in large Maglite torches.

To recharge C and D batteries, you need a battery charger capable of charging the C and D size batteries. While other C and D battery chargers do exist, the Maha Powerex MH-C808M C and D battery charger can charge 8 C batteries in 2.5 hours, or 8 D batteries in just 5.5 hours, and is also capable of charging AA and AAA batteries. It can charge any mix of different batteries at the same time, terminating the charge of each separate battery once the battery is full. By constantly monitoring the change in voltage (Delta V) of each battery, the battery charger ensures the battery is fully charged, but not over-charged. The status of the cahrge on each battery is also displayed on a backlit LCD screen, making it eacy for anyone in the family to use.
The MH-C808M includes a Conditioning feature to discharge batteries, which helps keep batteries heathey when they are not being used regularly. When conditioning/discharging with the MH-C808M, we recommended that you put the highest capacity cells toward the left of the charger as the heat from the discharge circuit is on the right. Higher capacity cells will generate more heat, so by keeping the higher capacity cells away from the heat, the charger and batteries will run cooler.
It is easy to see why Maha call the MH-C808M the “Ultimate Pro Charger”.
