Description
This is a pair of rechargeable D cells from Energizer, sold under the Recharge Power Plus name. The retail pack prints a capacity of 2500mAh and states that the cells are pre-charged, so they can go into a device straight away rather than needing a first session on a charger. The chemistry is NiMH, which puts each cell at 1.2V rather than the 1.5V of a single-use alkaline D. That lower nominal figure is normal for rechargeable cells and is worth knowing before you compare the two on paper.
D is the largest of the common cylindrical sizes, and it tends to live in the things that either run for a long time or pull hard: torches and camping lanterns, portable and site radios, larger children's toys, and floor standing clocks and chimes. Those are the jobs where single-use cells get replaced often enough to become a running cost, which is the argument for rechargeables in the first place. If a device already takes alkaline D cells, these are the same physical size and drop into the same compartment.
You will need a charger that handles NiMH D cells, as one is not included here, and a charger built only for AA and AAA will not physically take this size. Each pack holds two cells, and the minimum order is six packs sold in multiples of six, which works out at twelve cells in total. Buying in a set suits rechargeables: a charged pair on the shelf means the torch is never out of action while the other pair is charging. We stock Energizer cells in AA, AAA, C, D, 9V and lithium coin sizes, along with an Energizer charger supplied with AA cells.

Frequently Asked
Do these arrive ready to use?
The pack states that the cells are pre-charged, so you can fit them on the day they arrive. If they have sat unused for a while, give them a top-up charge first.
Can I use these in place of ordinary alkaline D batteries?
They are the same physical size and sit in the same compartment. Each cell gives 1.2V rather than the 1.5V of an alkaline, so check that your device is happy with that.
Is a charger included?
No, this pack holds the two cells only. You will need a charger rated for NiMH cells in the D size, as AA and AAA only chargers will not take them.
What does 2500mAh actually tell me?
It is the capacity printed on the pack, meaning roughly how much charge the cell holds. At the same current draw, a higher figure means longer between charges.
How many cells do I receive?
Two cells make up one pack, and the minimum order is six packs in multiples of six, so the smallest order is twelve cells.
How many times can they be recharged?
The manufacturer does not print a cycle count on this pack, so we do not quote one. Charge them on a NiMH charger and follow its instructions.
