Sanyo Eneloop Pre-Charged Rechargeables Review



Best Cheap AAA NiMH. The newest generation of Sanyo Eneloop pre-charged rechargeable NiMH batteries wins the top spot for its low rate of self-discharge, long life while in use, and recharge capacity. This AAA version offers 800 milliampere hours and can be recharged up to 1,500 times. Expert tests and consumer reviews concur that this battery delivers a star performance.

Sanyo Eneloop reviews show near-universal agreement that these AAA NiMH batteries (starting at $9.50/4-pack, Amazon) perform well and last a long time. After conducting a test of low-self-discharge rechargeable batteries, a hobbyist writing at reported that the 2,000 mAh Sanyo Eneloop had dropped only 33 mAh in the six weeks since its last recharge. Other batteries had discharged more than 100 mAh in the same timeframe. The reviewer predicted that the Sanyo Eneloop would still have 1,410 mAh remaining after a year of use.

Naturally, most customers posting Sanyo Eneloop reviews haven't had a chance to verify that this battery can be recharged 1,000 times, as the manufacturer claims. However, reviews do attest to consistently great performance in high-drain devices such as cameras, Bluetooth headsets, and other electronics. The pre-charged batteries hold their charge for a long time, according to customer reviews on Amazon; many say the Sanyo Eneloop Pre-Charged Rechargeable is the best battery they've ever used in that respect. Overall Amazon users give it a near-perfect 4.9 out of 5 stars.

Sanyo is a pioneer in low-self-discharge NiMH batteries. The company seems to have created a technology that remains low-cost yet lasts a long time. We can't argue with hands-on test results and entirely positive customer reviews, which is why the Sanyo Eneloop Pre-Charged Rechargeables take our top spot.
