Good in the heat (where Lithium units are no no)

I have finally had enough recharging cyles on this set of batteries to have thoughts down. Charge leakage is as low as advertised. I been using these batteries for a thermometer/hygrometer sensor in the attic (where lithium batteries are a fire-hazard). Glad to report that the batteries havee been holding up really well under the heat of the attic. The other set of batteries are used in sensor to monitor the garage during the cold snap. was surprised to have found that the cold nights discharged the batteries just a bit faster than the attic (could just be due to these specific batch ) All things considered, they are good products and the advertisements are not exaggerated. Thanks team Walmart.

Love Eneloop!

We've been using Eneloop rechargeable batteries for *years*. They have saved us so much money over disposable batteries! Unlike usual rechargeables, they hold their charge for a long time, which means you can charge them up, put them in the case, and they will be ready to use months later when you need them. It has taken us a while to buy enough Eneloop batteries to replace all the batteries we have in our various remotes and devices. I'm so glad Walmart.com carries them now! They really save me when the kids are using electronics a lot, as they used to burn through a lot of batteries. The Eneloop ones hold up well with high-demand devices (love them for my digital camera), and since they hold their charge when not in use, I can put fresh ones in my camera, take some pictures, then store my camera for months and still have plenty of power left when I pull it out to shoot more pics. The other awesome feature is that the batteries are ready to go fresh from the package! I wish more stores carried them. I take a charger and a couple of little clear 4-battery packs on trips to keep our devices powered up With the C and D adapters available, we only buy 9 volt disposable batteries now. Eneloop batteries are completely worth the investment, you won't be sorry.

Love rechargeable batteries

I usually buy these from Costco when they are on sale. However, it is a package deal with charger and 2 types of batteries. You often only get 4 of the triple a batteries. I needed more triple a batteries, and this was the best price around. I have been using Eneloop rechargeable batteries for years and no complaints.
