Review: Puts Energizer To Shame - 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.
Review: Rechargeable batteries - I definitely recommend these rechargeable batteries. I use the for my outdoor ring lights and the last a long time.

## Questions & Answers

**Q: Is there any type of warranty on these?  I need alot of these, and at $7 each, I'm concerned about some of them not working.**
A: the warranty on these batteries is less than 6 months.  i purchased 40 of them 2 years ago, and 6 went bad after 2 charges.  it was more than 6 months after i purchased them, since i only use them in the fall, so the warranty was useless.  i had to eat the loss.  6 out of 40 is, to me, not an acceptable loss.

**Q: We bought a pack of 8 100000amh ni-hm batteries a year ago and i took them out of my partable latern to recharge them,  why wont they recharge?**
A: Many chargers require voltage in the battery to recognize that there is a battery in the charger.
So, it sounds like your batteries completely drained, and you have a 'dumb' charger.
This can happen with any rechargeable if it goes completely dead, if your charger requires 'seeing' voltage before it will charge.

**Q: do tenergy D 10,000 batteries come already charged?**
A: I am going to say no David. I can tell you I also bought a Tenergy Advanced Universal Charger TN190-4 Channel AA/AAA/C/D/9V Ni-MH Charger with LCD Display and USB Power Outlet and it takes about 8 hours to charge 4 at the same time. That is a conservative estimate. You may be able to do it in 7, but no less I am sure of that.

**Q: Will an Energizer brand charger work with these?**
A: Any good brand charger should charge 1-1/2 volt AAA, AA, C and D cell rechargeable batteries.  The charger should have automatic cutoff, to prevent overcharging that could result in a fire.  As with all electronic devices, care should be taken to prevent exposure to water sources during use.

### ⭐⭐⭐⭐ Best for electronics you use all the time
*by F***D on November 8, 2018*

I use these batteries for a boombox that takes 8 D cells. If the cells sit for a long time, they will self-discharge. Cells that have sat for a long time like this have a habit of being marked as "bad" by the Tenergy charger. Being old, wily, and cheap, I didn't want to buy replacements for the batteries that have failed in this manner. I connected the bad batteries to a benchtop power supply, set the voltage for 1.4V, and limit the current to 200mA. Make sure you connect the polarity the right way around! I let the batteries charge like this until the current started decreasing to less than 200mA. I've had to recondition three batteries this way. After they charge to 1.4V, I ran them in a discharge/recharge cycle in the Tenergy charger, and they perform just like new. The charger doesn't complain about them being bad anymore. So, my recommendation to potential buyers is to only use these batteries in products you use all the time. Don't park them charged in a flashlight you only use every six months, or they'll self-discharge, your flashlight will be dead, and you may have the same problems I had.
