I have a couple LED lanterns for emergency power outages that take D cell batteries and I'm thinking about investing in rechargeables and a high-quality charger. Before doing so I have a couple questions:
Chargers I'm looking at include the Maha POWEREX MH-C808M Charger (currently around $100 on Amazon) and the EBL 906 Smart Charger (currently around $30 on Amazon).
Batteries I'm considering are the Powerex 10,000mAh Low Self-Discharge NiMH Batteries, (MHRDP2) which are $26 for 2 and the EBL 10,000mAh batteries at half the price, $26 for 4.
Now I can understand why the Maha charger is more expensive than the EBL, most obvious is the size, however, what makes the Powerex batteries twice as expensive as the EBL? Do they have a slower internal discharge rate?
Secondly, I have a question about battery maintenance and storage. In my house, I have a home automation hub and the ability to turn on and off devices on a scheduled event. My line of thinking is this, can I leave the batteries in the charger after being fully charged and control when the batteries get charged at the outlet? I was thinking after the batteries are fully charged, cycling on the charger for a couple hours every two weeks to keep the batteries as fully charged as possible. Both chargers are supposed to be "smart chargers" so I wouldn't think overcharging them would be a possibility. The only thing I can think of is would keeping the batteries in an unpowered charger cause the batteries to discharge faster by completing a circuit through the charger between charging times?
Any thoughts?
