Meh...batteries are good, but the charger is questionable. It looks like a 2 channel charger meaning charging must be in pairs and it may be timer based. You probably could stick a nearly full battery in there and it'll charge for 10 hours or whatever with a current just low enough to prevent the batteries from self-destructing.
If the description is correct these are the older Eneloops. Newer ones hold the charger longer and are rate for 1500 cycles. That said, one charge a week for 20 years is 1040 cycles.
An 8 pack of newer Eneloops go for under $18 currently at Amazon. Combine that with this $11 smart charger from Sony. For $1 more, for the Eneloops and Sony charger, it's a much better kit. The Sony charger has independent channels so charging in pairs isn't necessary and it is able to determine when each battery is done charging rather than depend on a timer. Ships for free too since it's over $25 if you don't have Prime.
