A typical battery will last for a good couple of years, before you notice a significant reduction in quality. So, what do I mean by a reduction in quality?
I mean that the time between charges will start to decrease. At first you could get a few hundred shots between charges, but when this figure decreases to between fifty and one hundred, you know you need a new battery. (These figures are only a rough guide and vary between cameras. Also, cameras with the LCD screen consume more power than those without. As a rule of thumb, when the time between charges drops to about one third of the original value, replace the battery).
Unlike in a sex toy, having a poor battery will not affect the usage. It will simply be a case of getting fewer pictures per charge, and not a continuous 'weaker' vibration throughout. The quality of pictures is not affected, neither is the memory (as this is usually dependent on the size of the memory card instead).
When it comes to replacing a battery, steer well clear of second hand ones, even if they do seem to be half of the price. Second hand batteries will also have a short charge capacity. It is just like someone buying your old battery and expecting it to work like brand new.
In general terms, the more you spend on a battery, the longer it will last. This Nikon battery cost me fifty quid, and is worth every penny.
It has got Li-ion technology and can hold 1400mAh of power (sounds good, doesn't it. Unfortunately I don't have a clue what it means though). On the package it says you get up to 1600 shots per charge, but I only get about three hundred (ish). I do however use the LCD screen quite a bit, and don't use a mains adaptor when connecting it to the computer to transfer images etc.
The battery is charged the same way as my old battery was. You can either use the standard MH-18 quick charger or the MH-19 multi charger. With these charges, the battery takes three and six hours respectively to charge fully.
So far I have had this replacement battery for four months, and I have not noticed a decline in charge capacity.
Overall, this is a camera battery and I have said all that is possible to say about it in this review. Yep it works and costs fifty quid. Summed up nicely in half a dozen words. So then, why did I take a couple of hundred to sum it up?
