Replacing NiCd rechargeables with NiMH rechargeable batteries in solar lights, the better choice!

Many people have asked “can I use NiMH (Nickel Metal Hydride) batteries in my solar lights that have NiCd (Nickel Cadmium)?”  And the answer is, yes!  Not only can you replace with NiMH, but they are the better choice of battery as they have benefits that their NiCd counterparts don’t.

NiMH battery benefits:

1. Long shelf-life. They can remain unused for anywhere between 3 and 5 years. However, we recommend using your new NiMH rechargeable batteries sooner than that, gotta keep those solar lights shining. 🙂

2. No memory effect (compared to NiCd). NiCd batteries have issues with attaining a “memory” that will reduce the life of that kind of battery. NiMH can be partially charged (say, on cloudy days) and be fully recharged to their maximum capacity on the next full-sun day. There is a little discharge (trickle discharge) during storage, so it is best to put your NiMH batteries into your garden solar lights in the pre-dawn hours before a sunny day. Then they will be ready to go for your nighttime enjoyment.

3. NiMH rechargeables are considered more environmentally friendly than NiCd batteries. Cadmium is classified as a toxic element, so it needs to be disposed of properly. There are many recycling locations (from what we’ve seen, Target and Best Buy have drop-off bins at the front of their stores for battery recycling), but if for some reason they end up in the trash, NiCd are not good for landfills. NiMH batteries can be recycled (it is recommended), but it won’t be “bad” to toss them into the trash, should there be no options of recycling.

4. NiMH rechargeable batteries for solar lights are almost always more expensive than NiCd. But not at Your Solar Link! They offer NiMH batteries at the same price (and sometimes lower) than the NiCd counterpart. But never more! You won’t find a better deal than at Your Solar Link for NiMH rechargeable batteries, anywhere! They are priced to get your solar garden lights up and running with the best option available. The price you see is the price you pay: no hidden fees, shipping charges, sales tax (for our California customers), etc.!

Just remember, don’t mix the chemistries in your solar lights (if they take 2 or more batteries). Use only NiMH or NiCd, not one of each in your 2-or-more-battery lights. Also, typical lifespans of both batteries is about 2 years (of nightly operation/use). So, if you have had your solar lights for about 2 years and are noticing that the output is diminishing at night, it may be time for a replacement. Just be sure to go with NiMH rechargeable batteries. They are indeed the best option.

Solar on!
