Average Reviews:
(More customer reviews)The button on the positive end of the battery is about 1 mm shorter than a standard alkaline C battery. This shorter post prevents contact with the electrodes in my battery charger (Rayovac Model PS3, 4-cell).
UPDATE: 13 JAN 2011. I purchased a La Crosse BC-9009 for AA and AAA batteries (4 cell), and a MAHA MH-C808M for C and D batteries (8 cell). The MAHA will also do AA and AAA, so buy it if you only want one charger. However, the La Crosse is much smaller making it easier to take on travels. Both will recondition weak rechargeables, which extends cycles for 20 or more additional charges.
Both chargers accomodate Tenergy battery posts with no need to use foil to make contact with the post.
I was concerned about user comments on the MAHA about potential fires, so I only use it during the daytime when I am around. By contrast, I will leave the La Crosse on overnight, if required. The La Crosse unit allows rapid charging if in a hurry, but it is best to use the lowest charging rate (200 mA) to extend battery cycle life.
These chargers in combination with batteries supplied by La Crosse, or Sanyo Eneloop batteries purchased separately produce a use life almost as good as alkaline batteries. Overall costs are much lower than alkaline batteries.
Sanyo states that Eneloop batteries maintain around 85% of their charge when stored at room temperature for a year. I think other rechargeables are not even close.
You can add metal foil to make good contact for Tenergy batteries in the RayoVac charger. However, I recommend La Crosse or MAHA over any unit sold in local stores. La Crosse or MAHA will charge more effectively and batteries will last longer.
