Without further ado, here they are the best, along with their critical features, pros and cons and what people say about them.
EBL is a trusted and established name in the rechargeable battery industry. Their D cells hold plenty of juice and store well for years when fully charged.
Since these are NiMHs, you won’t have to worry about fully discharging them before recharging.
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.
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.
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.
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.
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.
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.
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?
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
Here are the three most important factors to think about when shopping for small, powerful rechargeable D batteries.
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.
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
