Replace battery on Celestron NexStar 4SE Star Pointer ?

I left the switch turn ON on my Celestron NexStar 4SE Star Pointer and the batteries died. It wasn’t obvious where the battery was. I read the manual and found that it took: 3-volt lithium battery (#CR2032)

Afer reading a few reviews, I ordered the Strip of 5 Genuine Sony CR2032. I read a lot of reviews about getting what you pay for with the cheaper ones.

After reading some forums I found where the battery compartment is. Here is a picture showing where it is:

I carefully pried the cover off with my fingernails. Under the cover was the battery:

I replaced the battery and put the cover back on.

Bike Lights

For the past nine months, I have been riding my bike to work. It’s a little over 7 miles each way. During the summertime, there is plenty of light in the morning and evening. In October of 2013, when it started getting darker earlier, I had to upgrade my bike lights. I ended up with a Lumina 700 for my headlight and a Serfas Thunderbolt for my taillight. I’ve been very happy with both. I’ve had other bikers, people in cars and people on the road ask me about both of them. They’ve been impressed about how bright they are. Here are some more details.

Lumina 700

NightRider Lumina 700
What I like about the Lumina 700:

  • It has three levels of brightness. It’s plenty bright to light up the dark road on my route where there are no street lights.
  • It has a flash mode with I use for daylight riding. It’s super bright and cars can see me
  • It’s rechargeable via USB. I usually charge at night, but when I forget it’s easy to plugin at work.
  • It’s light weight

You can read all the specs at the Lumina 700 product page. It’s a great light and I highly recommend it. You can buy the Lumina 700 on Amazon for $97. That about $20 cheaper then when I bought it.

Serfas Thunderbolt USB Taillight

What I like about the Serfas Thunderbolt:

  • It’s the brightest taillight I’ve ever seen. I’ve had several people comment on that.
  • It’s rechargeable via USB. I usually charge at night, but when I forget it’s easy to plugin at work.
  • It mounts on the seat post and is very easy to put on or remove.

You can read all the specs at the THUNDERBOLT (USB) TAIL LIGHT. You can buy the Serfas Thunderbolt on Amazon for $36 – $45 depending on the color.
