I’m on the 1900 eneloops and swear by them. They say they do more recharges than the higher mah batteries.

My problem before these batteries was I used a battery charger that charges in 2’s such as:

Now this “did me reet” for a couple of years, but as the batteries are always paired with another battery for charging they only charge to the least depleted battery. Ie imaging having 4 batteries at 25%/25%/25%/50%
Forgive me if the science isn’t spot on, but this is the feeling I had after a few years of using the charger. Charging one of the 25’s with the 50 will get 100% and 75%. If we repeat the process of using the batteries then we get 3 batteries with 25 and one with 0.
On recharge we get 100% and 75% however I think the point is probably more subtle than that, as I’m sure the simple charger can never be as precise as getting the batteries to 100. But getting to the point, you will always have a battery or two which is letting the side down.
I now use a charger which charges the AA’s separately, sorry for labouring the point if you already use a charger such as this, but after having my first rechargeable which would last maybe a year, to the rechargeables that I use now which have lasted about 6-7, I now swear blind by the charger. There are others on the market!

There are other intelligent chargers on Amazon, but I have no idea of their quality and cannot vouch for something I haven’t tried.
