What Customers Are Saying

Some people have complained that EBL batteries are made in China in their EBL rechargeable battery reviews.

But what’s the difference? You want a good battery. These are good batteries. It doesn’t matter where they’re made.

Many have commented that EBL has excellent customer service. There have been reports of the unavoidable, occasional bad battery. EBL is quick to send free replacements.

Pros

  • Good power
  • Long life
  • No memory effect

Cons

  • There have been customer reports that their batteries tested at only 8,000mAh.
  • These reports are rare, isolated and unconfirmed. We’re sure that EBL would replace the batteries in question

Best Rechargeable D Batteries Lithium

Our Rating

Highlighted Features Of The Product

  • Lithium Ion – Lightweight, safe and long storage life
  • 5,000mAh – Decent power
  • 1,000 recharges possible – Pretty long life
  • Recharges with mini-USB – No need for a traditional battery charger

Overview

Have you ever seen batteries that have mini-USB charging ports in the side of them? You just plug them up like you would a phone.

Lithium-ion batteries are light, which is great for flashlights and other devices that you have to carry with you.

They don’t have the largest power reserve or lifespan, but that’s the trade-off for the convenience you get.

What Customers Are Saying

People love the convenience of not having to bother with a big, bulky battery charger. The novelty of a battery that can be directly charged with a mini-USB charger has been a big selling point too.

These same people do lament that these batteries don’t hold as much power as NiCads and NiMHs, though.

Pros

  • They’re just cool
  • No need for a regular charger
  • Low risk of leakage
  • Lightweight
  • Long storage life

Cons

  • They hold about half the power of traditional rechargeables
  • They don’t quite have the lifespan of traditional rechargeables either

Best Rechargeable D Batteries 10000mAh

Our Rating

Highlighted Features Of The Product

  • NiMH – Strong and durable
  • 10,000mAh – Plenty of reserve power
  • 1,200 recharges – Years of service
  • Pre-charged – Saves time

Overview

If you’re looking for economy, take a good look at these. AmazonBasics is essentially a no-frills brand. They save money on fancy packaging and advertising, and they pass the savings along to us.

These batteries are comparable to the big-name batteries at twice the price in terms of performance and longevity, but there have been reports of defects. Luckily, they are covered by a warranty.

What Customers Are Saying

Everyone likes to save money. That’s the biggest brag we see about these batteries. They are affordable, but they’re not shoddy.

They’re comparable to more expensive brand names in performance. People like that kind of value.

Pros

  • Economical
  • Great power reserve
  • Can be reused for years

Cons

  • There seems to be an excessive amount of defective batteries sent to customers. The good thing is they are covered by a 12-month warranty, and Amazon is happy to replace bad batteries.

Best USB Rechargeable D Cell Batteries

Our Rating

Highlighted Features Of The Product

  • Lithium ion – Lightweight, leak-resistant and good for long-term storage
  • 5,000mAh – Ideal for low-drain devices
  • 1,000 recharges – Can be used for a couple years, even if recharged daily
  • Mini-USB charger included – Great value
  • Charging Time 4 Hours
  • Output Current ≥2.5A

Overview

Here’s another set of direct-charge batteries. Just plug a mini-USB in them and charge for four hours.

They share the same disadvantages of this type of lithium ion battery, though. They don’t quite measure up to NiCads or NiMHs as far as performance goes.

What Customers Are Saying

Customers like that a charger is included with purchase. That saves money, or at least keeps them from having to use one of their phone chargers for the batteries.

On the flip side of the coin, people have complained that the included charger is of low quality. But what can you really expect at this price?

Pros

  • Light enough for all-day carry in cameras and flashlights
  • No need for a charger
  • Lithium ion batteries are inherently resistant to leakage

Cons

  • The charger that’s included is cheaply made and may not work long

Best 1.5v D Cell Battery

Our Rating

Highlighted Features Of The Product

  • Lithium ion – Necessary for some devices
  • 4,000mAh – Decent amount of reserve
  • 2,000 recharges – Excellent for USB-rechargeable D cells
  • Plug-n-play – No need for a charger
  • USB Rechargeable
  • Charged time: 3-5 hours

Overview

The big difference between these and the previous two USB-rechargeables on our list is the way these ones charge. There is no cord to worry about. You just slide the charger over the top of the battery and plug it into a USB port.

Another difference is the longevity. These last through twice as many charging cycles. Just be aware that these have a slightly lower mAh rating.

What Customers Are Saying

Even those who have owned other USB-rechargeable batteries comment on the design of these. Instead of plugging into the side of the battery, the charger slips over the top. Then the whole thing plugs into a USB charger. People like that simplicity.

As far as dependability goes, there are some who have been using the same set of these batteries for over three years. That’s a testament to their dependability.

Pros

  • Simple charger design – No cord to lose
  • Very long life – Can be charged about 2,000 times
  • Lightweight

Cons

  • 4,000mAh is not much of a power reserve, but they’ll work just fine in low-drain devices

Our Rating

Highlighted Features Of The Product

  • NiMH – Great power reserve and no memory effect
  • 10,000mAh – Strong long-lasting power for high-drain devices
  • 1,200 charges – Years of service
  • 1.2v instead of the usual 1.5v – Slightly less power but longer life between charges
  • Pre-charged – No need to charge before use

Overview

These are best bought in the pack of eight to take advantage of the savings.

Even the best NiMH D cell batteries need to be replaced every so often, even rechargeable ones. If you use your batteries heavily, you can probably save a bunch by stocking up on these.

What Customers Are Saying

People talk about the savings. Those who use their batteries very frequently often have to replace their D cells yearly. That’s pretty much unavoidable. But these batteries are so economical, no one really minds when they have to replace them.

Many have said that when they checked their new RayHom batteries on their chargers, they weren’t fully pre-charged. The average seems to be about 80 percent. That’s not really a big deal, though.

Pros

  • Economical, especially for people who use their batteries all the time
  • Lots of reserve power
  • 1-year warranty

Cons

  • They’re advertised as being fully charged when you buy them, but they are usually short by about 20 percent

Our Rating

Highlighted Features Of The Product

  • NiMH – Best for high-drain devices
  • 10,000mAh – The standard for high-performance rechargeables
  • 1,200 recharges – Should last for years of daily use
  • Deep cycle – Made for fast drain

Overview

Don’t be confused by the term “deep cycle.” In this context, it simply means that the battery was designed with chemistry that lets them store a bit more power.

They’re rated at 10,000mAh, but they actually should be around 11,000mAh. It’s a little more reserve power, but that can come in useful when you need it.

What Customers Are Saying

Many rechargeable D battery reviews mention incompatibility with devices that hog power, like boom boxes and bright flashlights.

These ones got glowing reviews from professionals who rely on batteries to do their job. Even a police officer said that these batteries lasted longer than standard alkaline ones in his big MagLite flashlight. Those lights are bright and suck up a lot of power.

Pros

  • Long-lasting power
  • Affordable

Cons

  • Although Odec does honor the warranty, there have been numerous reports of batteries refusing to take a charge after just a few recharging cycles.

Our Rating

Highlighted Features Of The Product

  • NiMH – No memory effect and plenty of power for all devices
  • 10,000mAh – Plenty of juice
  • 1,200 charges – Lasts for years
  • Pack of 4 rechargeable batteries
  • Voltage: 1.2V
  • Good replace standard C size batteries

Overview

Several buyers have tested these batteries after charging them for the first time, and they say that they are truly 10,000mAh. This is worth mentioning because many batteries vary somewhat in their actual power reserve capabilities.

The reviews for these batteries are consistently good. We were hard pressed to find any complaints about defective or weak cells.

What Customers Are Saying

Most people had the best results when they charged them for a full 24 hours before their first use. That’s what experienced people do, and it seems to help them hold more power and last through more charging cycles.

Pros

  • Guaranteed 10,000mAh
  • Totally decent life span – Great life span if you charge them for a full day before their first use.

Cons

  • This seller is relatively new on the scene, and we don’t how how responsive they are when it comes to warranty claims

Our Rating

Highlighted Features Of The Product

  • NiMH – No memory effect and the best power
  • 2,500 mAh – The typical reserve of a AA battery for reduced price
  • Up to 1,000 recharges – Decent life
  • Voltage: 1.2 V

Overview

Understand this right away: These are basically AA batteries in a D-cell body.

But why would such a trusted battery manufacturer be so deceptive? It’s not a deception. It’s an ingenious solution that’s meant to save their customers money.

These batteries are meant for low-drain devices that require D cells, like LED flashlights and anything else that could get by with cheaper AAs if such a small battery would fit in them.

What Customers Are Saying

Many are surprised by the low power reserve when compared to other D cells. They don’t understand what this battery actually is and what it is meant for.

Those who do understand are pretty happy with their purchase. These batteries are great for low-drain devices, and those who use them in that application say they would make the same decision again.

Pros

  • Good price compared to regular rechargeable D cells
  • Made by a trusted manufacturer

Cons

  • Terrible performance and short life in high-drain devices

Factors To Consider When Buying The Best D-size Rechargeable Batteries

Here are the three most important factors to think about when shopping for small, powerful rechargeable D batteries.

Reserve Power

This is the amount of electrical energy they can store. It’s measured in milliamp-hours or mAh for short. Most D cells have a rating of 10,000mAh. That’s a good rating for any device. But there are D batteries as low as 5,000mAh. They’re best for low-drain devices. They can be used in anything, but high-drain devices will run their charge out more quickly.

Type

The two main types are nickle-cadmium, or NiCad, and nickle-metal hydride, or NiMH. NiCads are cheaper; NiMHs perform better. Understand memory effect. It’s a battery’s tendency to lose its ability to take a full charge if it is not completely drained between each recharge. NiMH batteries don’t have a memory effect, but NiCads do. If you do get NiCads, be sure to allow them to run almost completely dead before recharging.

NiMH batteries typically have a higher reserve capacity than NiCads. They also have a longer lifespan and are more resistant to leaking. NiMH batteries are the hands-down winner. That’s why they’re the only ones we recommend. Only get NiCads if you want the absolute cheapest.

Lithium-ion batteries have no memory effect either. Their main advantage is safety. They cannot leak, but even if they do, their chemistry is pretty much non-toxic.

Lifespan

This refers to the number of times a battery can be recharged before it will no longer accept a charge. Most rechargeable D cells can be recharged 1,000 times or more. Some have a chemistry that only allows a few hundred recharges, but offer a higher mAh rating.
Pay close attention to the lifespan if you want your batteries to last for a long time. If your main consideration is upfront cost, you may want to accept a shorter lifespan in exhange for a lower price.

Conclusion

If you’re looking to go super cheap, we’d recommend AmazonBasics D cells. But if you’re willing to spend a little more for an extra layer of dependability, get the EDLs. But what about those cool USB-chargeable Fluvals? Go for them if you don’t have a charger and don’t want to buy one.

If you don’t want one of our picks, just make sure you get NiMHs or lithium-ions. Check out the mAh rating and lifespan before you buy.

Keep what you learned here in mind when you make your decision. Now you know how to do it. Go get yourself a pack of the best rechargeable D cell batteries
