The Tenergy 10000mAh NiMH D rechargeable batteries are excellent, we use them for our Jeff Rowland Criterion preamplifier.

I was shocked to find out that the D-size rechargeable batteries sold by Energizer are really just AA cells in a bigger casing. What a rip-off. 2500 mAh just won’t cut it for the types of applications that D-sized cells are used in.
We have a baby swing that requires 4 D batteries. This swing makes our lives infinitely easier. It allows our daughter to fall asleep on a whim, which is amazing. I was buying alkaline D cells every 3 weeks to keep this thing powered, and it was getting expensive. I already had a charger that can handle D-sized cells, so I started looking for rechargeable Ds, and learned the awful truth about Energizers. With 2500 mAh cells, I’d be recharging batteries every 2-3 days!!! Not to mention that NiMh batteries have a much lower voltage than alkalines, so the swing (which doesn’t have a voltage regulator) would be running much slower the whole time while pulling max output from the batteries.
The solution was a combination of 2 things: these Tenergy 10,000 mAh D-sized cells, and a secondary battery holder for the swing to add 2 more batteries. The battery holder was very easy to put on, just cut one of the power wires on the swing and connect each end to the wires on the battery holder. I attached it to the swing using Velcro tape. Now the swing uses 6 D batteries. So instead of 6 volts alkaline (4x 1.5v), it now has 7.2 volts NiMh (6x 1.2v). Why the extra 1.2v, you ask? Easy, now I can run the swing at level 5 and get the same speed I used to get at level 6 (max). This prevents the batteries from getting warm and helps them last even longer. Still not as long as alkalines used to last, but long enough that charging the batteries isn’t a chore. I’d say we get about 2 weeks out of a charge, vs the 3 weeks we used to get from alkalines.
We bought a total of 12 Tenergy 10,000 mAh D-sized cells, one set for the swing and one set to keep charged as backups. A set of 6 takes about 10 hours to charge. We need the spare set because when these batteries lose their charge, they die very suddenly. It’s not a gradual slow-down like it was with Alkalines, where I’d have a couple days’ warning to let me know to buy fresh batteries. These things go from full speed to completely dead in less than 10 minutes.
Now my 5-month old daughter can swing away and sleep without the incessant cost of alkaline D batteries! I have a feeling she’ll be using it for many months to come.

I use batteries for a lot of things and rechargeable NiMH batteries excel in almost every application (much better than NiCads which can develop a “memory” that reduces their charge capacity.) In a head-to-head performance test between the Tenergy standard NiMH D cells and Ray-O-Vac “Hybrid” NiMH D cells, the Tenergy out-perform by a wide margin. They run wireless outdoor speakers for hours longer than a set of Ray-O-Vac “Hybrid” D cells. My friends installed 4 Ray-O-Vac “D” Hybrids in one speaker and 4 Tenergy standard D cells in a duplicate speaker and ran them equally over time and recharge cycles. A Tenergy charger is used to recharge them. The Tenergy batteries have performed so well that I bought them another set of Tenergy D-size NiMH to replace the Ray-O-Vacs. (Not that it’s necessarily an indicator of capacity or quality, the Tenergy NiMH batteries are noticeably heavier than other brands of NiMH rechargeables of the same size.)
I was happy with the Ray-O-Vac NiMH AA and AAA “Hybrids” compared to rechargeable Duracell, Energizer and Sears brand AA and AAA batteries because they provided almost twice the running time in a pair of Uniden walkie-talkies that I keep on 24/7/365 to keep in touch with my 93-year-old mother for whom I’m the sole caregiver.
I experienced even better performance with the Ray-O-Vac AA and AAA “4.0” NiMH batteries. I’ve been using 4 sets of three “4.0” batteries in the walkie-talkies, alternating them each day. Been using the same batteries for almost two years now.
However, I am now changing over to Tenergy brand for all my applications based on the outstanding performance of the D-size “standard” Tenergy batteries. I have started using the “premium” AA size in normal applications such as solar outdoor pathlights, for example, which discharge/charge regularly. I am installing the LSD (Low Storage Discharge) Tenergy AA batteries in my emergency LED lanterns so they will be ready in a power failure without having to worry about frequently checking them and recharging them. When I have exhausted my supply of Ray-O-Vac “4.0” NiMH AAAs, I will replace them with Tenergy also.
Until some company comes up with something better, I’m going Tenergy all the way!

Dejaron de servir en un mes, el cargador muestra bad battery y no cargan ya

These are useful batteries. Most uses for “D” cells are high-drain applications, and these Tenergy cells deliver more power in once charge than disposable alkaline cells do in their lifetime. If you’re splurging on batteries, be sure to get a good charger to go with them. These really need a charger that monitors each cell separately when you’re charging a set, as Tenergy’s TN-190 (which will charge four of them at a time) does.
The battery chemistry used in NIMH cells mean that they produce a lower voltage (around 1.3V) rather than the 1.5V alkaline cells do. This is not normally a problem, since most devices will operate fine at that voltage level. However, some device battery meters will report that NIMH batteries are not fully charged even when they are. It’s not a problem, but it is something to keep in mind.
