About 18 months ago I posted a thread about rechargeable batteries. On the advice of the majority of posters therein, I bought a number of Sanyon Eneloop batteries and a good charger for them.

They have worked wonderfully and I love them.

Moving on to present day, I find myself using TONS of 'D' cell batteries in trail cameras - I maintain a couple of cameras on our land and 3-4 on my dad's land. This is getting expensive.

So, the point of this thread: who makes a good 'D'd rechargeable?

I noticed an adapter to convert an AA to 'D' use here: http://us.sanyo.com/Battery-Products/eneloop-D-Spacer-Kit and was wondering if that was a good option, or if I would be better served by a specific 'D' cell.

The Maha Immedion batteries are pretty decent - They're low self-discharge like Eneloops.

Maha also makes a standard-discharge version with a little higher capacity (11,000 mAH).

Using AA to D adapters works OK for low-drain devices, but a device that quickly drains 20,000 mAH alkaline D-cells ain't gonna last long with 2,100 mAH AA cells in it instead.
