## Description

Mighty Max Battery ML5-12 - 12V 5AH Chamberlain 41A6357-1 Garage Door Opener Battery

Review: Fits perfectly, use duct tape! - This battery is exactly the same size, etc., as the one that came with my garage door opener. It was super easy to put in and now that I’ve had it in use for a month -seamless performance. The hardest part about installing it was actually getting the old battery out since there is nothing to grip and it’s a tight space. After experimenting trying all kinds of skinny tongs and skinny stuff from the garage to try and wiggle it out. I hit a pun a little stroke of MacGyver genius – took a long piece of duct tape and used a table knife to stick it to the top and bottom of the battery then it pulled out very easily. So my new battery already has a piece of tape stuck on it so next time it won’t be so hard to change. 😃
Review: Its a solid battery that does what its supposed to do - Its a battery. fits perfectly into the garage door opener, and worked from the first time replacing it.

## Questions & Answers

**Q: Will this power a cyberdyne systems series t-800 model 101?**
A: No. This might power the Cyberdyne Systems Model T-101, but definitely not the T-1000 or better. You would need a kyber crystal battery.

**Q: Does this battery replacev12v4.5ah battery for chamberlain**
A: I think it should. It is a 12V battery. But 5 amps not 4.5. You have to make sure the size is the same and that the electrodes are in the same position. Best to ask Chamberlain.

**Q: can I use this in my alarm system?**
A: Hi Gina.  Since I do not know anything about your alarm system, I can't say.  But, look at your current battery and if it is a 12 volt battery and is rated any where near 5 amp-hours (AH) or less, it should work.  The only other considerations would be the dimensions of the battery and connection to the battery terminals.

**Q: I have chamberlain model # rd850kevg would this be the correct battery unit?**
A: The Chamberlain owners manual will list the model of your battery or open the unit to get the existing battery model then search for its  relacement
