Review on Panasonic Generation Pre Charged Rechargeable Eneloop by Sergio Wingate

You've got to love how rechargeable battery technology has evolved over the years. And in my opinion, Eneloop is at the top. I have over 250 batteries (AAA, AA, C, D), most of them Eneloop. Some of these I use during the holidays (candles and displays) and others I use in my studio for gear (wireless mics, flashes, and other items). summer in a box When I take them out, only Eneloop is running at full capacity. Let's see how it works: Conventional (non-rechargeable) batteries • aa, aaa - $0.50 • Cell C - $1.00 • Cell D - $1.25 Rechargeable batteries • aa, aaa - $2.50 ( Eneloop) • Cell C - $3.50 (non Eneloop) • Cell D - $5.00 (non Eneloop) Note: To my knowledge, Eneloop does not sell C or D cell batteries • Prices may vary and they may cheaper or more expensive batteries may be available; However, this is the price I pay. Since Eneloop doesn't sell C or D batteries, the discussion will only be about Eneloop from now on. New 4th generation. Eneloop batteries can be charged 2100 times. This means that they will be just as effective on the 2100th charge as they were on the first charge and will start to fade from that point on. To put this in perspective, if you charge your batteries once a month, they will last almost 15 years. How much does it cost to charge an AA battery? That's a good question... I have a device called: Kill-A-Watt. , which measures how much electricity is used by most electrical products. So I decided to plug in my charger, add an AA battery and see what happens. It takes 0.02 kilowatt hours to recharge an AA Eneloop battery. Where I live now, we pay about $0.10 per kilowatt hour. I have about 100 AA batteries that I charge about once a month. That's less than $0.30 per year to charge 100 batteries per month. I confess that it really surprised me. FYI: If you want to measure the power output of your electrical devices, I use this: https://www.amazon.com/gp/product/B000RGF29Q/ref=ox_sc_act_title_1?smid=ATVPDKIKX0DER&psc=1ChargerOne of the main accessories you need is a charger. Some cheap chargers will overcharge batteries and shorten their lifespan. Used by PowereEx: https://www.amazon.com/Powerex-MH-C9000-WizardOne-Charger-Analyzer-Batteries/dp/B003DIGKOG/ref=sr_1_4?ie=UTF8&qid=1533502678&sr=8-4&keywords=powerex It's not only allows 4 AA, AAA batteries to be charged simultaneously, but also allows you to precisely control the power at which they are charged. This is crucial for the long life of your batteries. Do I need rechargeable batteries? Well I guess it depends on how much you use. I am aware that my battery consumption is above average. I have 3 chargers worth $60 each and batteries worth over $750. As well as Eneloop rechargeable batteries (aa, aaa), I have the Tenergy brand for C and D sizes. With an initial investment of nearly $1,000, I've paid back my investment in 18 months and am now giving less than $1 a year off on batteries. To say it's stunning would be an understatement. Another point worth mentioning. When you charge your own batteries, you don't have to make a last-minute trip to the store to get new batteries. Please…
