Can I safely recharge Energizer NiMH 2500 and 2650 rechargeables in Duracell 15 minute fast charger without damaging them or shortening their life greatly?

Answer 1

Go to Energizer's website. It says that even energizer batteries recharged in an energizer 15 minute charger will only get about 150 charges, whereas batteries charged in an overnight charger will get around 500 charges. Duracell's website saysabout same. I just bought an energizer 15 minute charger that has a fan to keep the batteries cool and even with that they get very warm. One of the AA and one AAA battery actually leaked acid during their first charge.

Battery manufacturers always suggest telling you to use their batteries with their chargers. This is to put more money in their pockets, plus its the way they test their products. I have been using many diffterent NiMH batteries over the years, and several different chargers, so I would say yes you can use an energizer battery in a duracell charger. However based on the information found on Energizer's and Duracell's websites I would saydon't use a quick charger, you will shorten the lfe of the battery by 1/3 to 1/4. Your money is MUCH better spent on a slow overnight charger and an extra set of batteries to keep in it so you always have a set ready to go.
