If you're looking for an internal battery (EN-EL4A):

Jupio: my favorite, because it lasts the longest (~90 min)

Kastar: two batteries and a charger costing less than one Jupio, each usually lasts about ~45min for my Chronos 2.1

Alternatively you could use an external battery. I've tried a few, and so far my favorites are from FXLION or REYTRIC. These work with the Chronos 4K12 and Q12 models as well.

I've run my 1.4 for about an hour plugged into an inverter powered by a car jumper pack, with more battery life to spare.  Cheap, and it works.  I regularly run my 1.4 for 6-10 hours at a time plugged into an inverter in my car.

Is it effective if used for a long time?

Is it still effective after a large amount of time has passed? I want to buy it for my parents to use so I need a durable and good one. Any advice would be appreciated!
